00:00:01,566 --> 00:00:04,203
This is Alan Pope with the eighth screencast in the

2
00:00:04,303 --> 00:00:05,940
Ubuntu Month of Screencasts.

3
00:00:06,040 --> 00:00:08,407
All of the screencasts in this month can be downloaded for free

4
00:00:08,507 --> 00:00:12,626
at our website which is screencasts.ubuntu.com.

5
00:00:13,911 --> 00:00:18,225
In this screencast we are going to look at the contents of the Places and System menus

6
00:00:18,349 --> 00:00:22,051
Not everything, but most of the things in those menus.

7
00:00:24,459 --> 00:00:29,408
The places menu, you can see, consists of a bunch of bookmarks, at the top.

8
00:00:29,523 --> 00:00:32,347
First of all there is a link to your Home directory

9
00:00:32,447 --> 00:00:35,141
and here you can see all of the files that are in your home directory.

10
00:00:35,256 --> 00:00:39,130
and you can add to those bookmarks that appear on the left hand side

11
00:00:39,230 --> 00:00:41,772
and under the Places menu up here.

12
00:00:41,887 --> 00:00:45,594
You can modify that list, you can do that quite easily

13
00:00:45,880 --> 00:00:50,199
by just dragging a folder into the bookmark list.

14
00:00:50,333 --> 00:00:52,397
and straight away you've now got a new bookmark

15
00:00:52,497 --> 00:00:56,352
and when you double-click that bookmark it takes you to that folder

16
00:00:57,289 --> 00:01:01,550
You can see under the Places menu it's now created a bookmarks folder

17
00:01:01,650 --> 00:01:04,856
because we've got more than a certain number of bookmarks

18
00:01:04,956 --> 00:01:07,111
it's created a kind of sub folder.

19
00:01:07,263 --> 00:01:10,474
And if we navigate to one of those sub folders

20
00:01:10,799 --> 00:01:14,506
we get taken straight to the window.

21
00:01:16,054 --> 00:01:18,514
Going back to our home folder, we can also manage

22
00:01:18,614 --> 00:01:20,960
our bookmarks from the bookmarks menu.

23
00:01:21,175 --> 00:01:23,846
We can here there's my bookmark listed at the bottom.

24
00:01:23,946 --> 00:01:26,888
We can remove them from there as well.

25
00:01:32,602 --> 00:01:35,297
Also under the Places menu

26
00:01:35,545 --> 00:01:38,048
there is a link that just says Computer

27
00:01:38,258 --> 00:01:42,061
and from here we can see Filesystem.

28
00:01:42,161 --> 00:01:46,915
Which is the top level of the hierarchy of files and folders on the disk

29
00:01:47,030 --> 00:01:49,471
and this is the top level here many files and folders

30
00:01:49,571 --> 00:01:52,934
that we general don't touch and don't use.

31
00:01:53,106 --> 00:01:55,204
In fact we don't have rights to touch and use

32
00:01:55,304 --> 00:01:57,367
other than the home directory.

33
00:01:57,635 --> 00:02:00,936
There's also access to removable devices, like CD-ROMs

34
00:02:01,036 --> 00:02:05,814
and memory sticks and other mountable devices.

35
00:02:06,311 --> 00:02:08,737
Beneath that there is a CD/DVD Creator,

36
00:02:08,837 --> 00:02:11,948
this is a simple CD burning application.

37
00:02:12,311 --> 00:02:15,712
You can go to somewhere on your file system,

38
00:02:15,865 --> 00:02:18,636
grab some files and just drag them into that window.

39
00:02:18,827 --> 00:02:22,148
And then you get the option to write those files to disk.

40
00:02:22,362 --> 00:02:25,916
So you just put a blank CD or DVD in, hit Write to Disk 

41
00:02:26,088 --> 00:02:30,999
and it will write at whatever speed you specify in the pop-up dialog.

42
00:02:32,929 --> 00:02:36,484
Also under the Places menu is the Network option.

43
00:02:37,325 --> 00:02:42,197
Now within this we can navigate to other hosts on the network.

44
00:02:42,389 --> 00:02:47,682
Specifically we might use this for browsing shares on a Windows network.

45
00:02:47,796 --> 00:02:52,421
I don't have any Windows machines on my network, so I can't actually show you that right now.

46
00:02:52,536 --> 00:02:56,429
But if you look at one of our other screencasts on Samba file sharing,

47
00:02:56,529 --> 00:02:58,536
you will see how that is used.

48
00:02:58,650 --> 00:03:00,848
We can also connect to servers,

49
00:03:01,001 --> 00:03:03,389
specifying a Server name

50
00:03:03,924 --> 00:03:05,740
and Share name

51
00:03:05,893 --> 00:03:10,154
and other credentials, such as your username and so on.

52
00:03:10,345 --> 00:03:13,436
Now we can connect to Windows shares, SSH servers,

53
00:03:13,536 --> 00:03:18,619
FTP servers and various other protocols can be used.

54
00:03:18,772 --> 00:03:21,367
And this is useful for creating a shortcut on the desktop

55
00:03:21,467 --> 00:03:25,040
or on the Places menu to connect to a remote server.

56
00:03:25,537 --> 00:03:30,410
We can also use the search option under the Places menu, to search for files.

57
00:03:30,562 --> 00:03:32,335
So for example if I just type bots,

58
00:03:32,435 --> 00:03:35,187
it finds a whole load of music that I've downloaded.

59
00:03:35,378 --> 00:03:37,705
If I type lugradio, it finds some podcasts.

60
00:03:37,805 --> 00:03:42,487
And these are all files that it's found within my Home directory.

61
00:03:43,461 --> 00:03:46,743
There are various options, which you can join together

62
00:03:46,843 --> 00:03:50,775
So I could say, find only files that are of a certain size

63
00:03:50,875 --> 00:03:54,716
and were created within a certain period and so on and so on.

64
00:03:54,850 --> 00:03:58,252
So you can join together criteria to find your files.

65
00:03:58,481 --> 00:04:02,107
And finally on the Places menu there's a recently used list.

66
00:04:02,207 --> 00:04:06,774
So here I can just click on something from the recently used list, in this case it's a video

67
00:04:06,889 --> 00:04:11,227
and it open up the video player, Totem and plays the video.

68
00:04:12,010 --> 00:04:14,490
So it keeps a list of the recently accessed files,

69
00:04:14,590 --> 00:04:17,624
which you can clear out by using clear recent documents

70
00:04:17,724 --> 00:04:19,768
So if this is a shared user ID,

71
00:04:19,868 --> 00:04:23,437
then I might want to do that, to clear out that list.

72
00:04:23,762 --> 00:04:25,955
Or if you just like being tidy, you can clear it out.

73
00:04:26,055 --> 00:04:28,248
You can see the option is grayed out,

74
00:04:28,348 --> 00:04:31,138
once you've cleared that list out.

75
00:04:31,960 --> 00:04:34,349
So that's a brief run down of the Places menu.

76
00:04:34,501 --> 00:04:37,559
On the System menu we've got access to the on-line help.

77
00:04:37,674 --> 00:04:42,389
I say on-line, it's inside the distribution, it's part of the distribution,

78
00:04:42,489 --> 00:04:44,992
so it doesn't have to connect to the Internet for that. 

79
00:04:45,126 --> 00:04:47,840
We also have the Preferences and Administration menu.

80
00:04:47,940 --> 00:04:50,190
Let's have a look at Preferences for now.

81
00:04:50,343 --> 00:04:53,916
First item on the Preferences is to do with the assistive technology

82
00:04:54,146 --> 00:04:56,664
So this is where we can set accessibility options

83
00:04:56,764 --> 00:05:00,829
for perhaps people who have difficulty using a keyboard

84
00:05:00,929 --> 00:05:03,566
or maybe have poor eyesight.

85
00:05:03,681 --> 00:05:06,639
And there are numerous options in here for specifying

86
00:05:06,739 --> 00:05:10,541
which applications we're going to use to assist us

87
00:05:10,732 --> 00:05:14,263
and also settings for keyboard accessibility

88
00:05:14,363 --> 00:05:18,529
like sticky keys and other useful options.

89
00:05:19,733 --> 00:05:21,926
Now there is also an option here for accessible login

90
00:05:22,026 --> 00:05:24,066
and it mentions this GDM Setup

91
00:05:24,166 --> 00:05:26,536
we'll come back to this GDM Setup later,

92
00:05:26,636 --> 00:05:29,536
but GDM Setup configures the logon screen.

93
00:05:29,708 --> 00:05:32,861
GDM is one of the programs that provides the logon screen

94
00:05:32,961 --> 00:05:34,275
and GDM Setup is this one

95
00:05:34,375 --> 00:05:37,714
And you can see there are further accessibility options here

96
00:05:37,814 --> 00:05:42,109
to make the logon screen accessible.

97
00:05:44,785 --> 00:05:48,870
Also under preferences there's Keyboard Accessibility,

98
00:05:48,970 --> 00:05:51,817
which takes us directly to a dialog we have just seen.

99
00:05:52,008 --> 00:05:55,772
So here we can enable the keyboard accessibility features, at the top

100
00:05:55,944 --> 00:05:59,460
and that allows us to switch on Sticky Keys

101
00:05:59,560 --> 00:06:02,575
So for example it will enable us to toggle

102
00:06:02,675 --> 00:06:06,474
certain keys to hold them down, without actually having to physically hold them down,

103
00:06:06,593 --> 00:06:12,206
which is difficult for people with certain disabilities

104
00:06:12,627 --> 00:06:15,527
Also under the Preferences is the About Me screen.

105
00:06:15,627 --> 00:06:17,514
In here you can change your password,

106
00:06:17,614 --> 00:06:19,138
fill in some details about yourself,

107
00:06:19,238 --> 00:06:21,035
which could be used by other applications

108
00:06:21,168 --> 00:06:24,417
and also select an image, an avatar or a face.

109
00:06:24,589 --> 00:06:26,844
I'll just pick this fish.

110
00:06:27,016 --> 00:06:30,126
Now this image will appear when your screen is locked

111
00:06:30,226 --> 00:06:32,729
If you move the mouse while the screensaver's kicked in

112
00:06:32,901 --> 00:06:35,591
you'll get a dialog asking for your password

113
00:06:35,730 --> 00:06:39,341
and that's where you'll see that image and a few other places as well.

114
00:06:39,456 --> 00:06:42,934
And there's plenty of other fields for you to fill in as well.

115
00:06:44,309 --> 00:06:47,152
Another option is Appearances, under the Preferences menu

116
00:06:47,252 --> 00:06:50,405
and this is setting your own appearance for

117
00:06:50,505 --> 00:06:52,866
just the user account you're currently logged in to.

118
00:06:52,966 --> 00:06:56,654
So each person can have their own preferences, their own settings.

119
00:06:56,773 --> 00:06:59,329
And here there is a theme, which controls the look and feel

120
00:06:59,463 --> 00:07:03,552
of the titles and all of the other elements on the screen.

121
00:07:03,705 --> 00:07:07,202
and there's some high contrast and large font versions there.

122
00:07:07,374 --> 00:07:09,949
And if I just choose one of these themes

123
00:07:10,049 --> 00:07:13,179
you'll see that pretty much instantly, things start to change.

124
00:07:13,279 --> 00:07:15,897
The window title changes the icons change

125
00:07:16,088 --> 00:07:19,164
all manner of elements on the screen change

126
00:07:19,264 --> 00:07:21,706
and if a choose a different one, it all changes back again.

127
00:07:21,859 --> 00:07:25,184
You can install additional themes and customize the themes.

128
00:07:25,432 --> 00:07:27,931
You can also change the background color,

129
00:07:28,031 --> 00:07:30,630
So you can make it a solid color or a gradient.

130
00:07:30,730 --> 00:07:34,108
or if you've got a picture, you can add it in with the Add button.

131
00:07:34,261 --> 00:07:39,191
Or you could just choose one of the already supplied images, like this.

132
00:07:39,573 --> 00:07:44,408
You could choose which fonts are used throughout the Ubuntu Applications.

133
00:07:44,580 --> 00:07:47,006
And you could choose the size in dots per inch

134
00:07:47,106 --> 00:07:51,168
the default here is 75 dots per inch and if I change that to 95,

135
00:07:51,287 --> 00:07:55,505
you'll see that the fonts jump to a much larger,

136
00:07:55,605 --> 00:07:57,688
possibly more readable size.

137
00:07:57,860 --> 00:08:01,754
There's also more options in here for LCD panels

138
00:08:01,854 --> 00:08:06,115
for optimizing the output on an LCD panel.

139
00:08:10,644 --> 00:08:12,880
Also at the top is Interface

140
00:08:12,980 --> 00:08:17,237
and under the Interface tab of the Appearance preferences dialog

141
00:08:17,524 --> 00:08:22,435
you can see, we can change some of the options for the way menus are presented.

142
00:08:22,683 --> 00:08:25,874
So for example, if I switch off icons in the menus,

143
00:08:25,974 --> 00:08:30,499
then the Applications menu here at the top of the screen loses all the icons.

144
00:08:30,633 --> 00:08:33,652
And this may make the menu appear quicker.

145
00:08:33,919 --> 00:08:36,308
Which is useful on a low spec machine.

146
00:08:36,518 --> 00:08:40,737
Also down here we can change the appearance of the toolbar within applications.

147
00:08:40,915 --> 00:08:44,367
So I've got the text editor open behind here

148
00:08:44,525 --> 00:08:49,914
and as I change these options, you can see the menu changes within the text editor.

149
00:08:51,691 --> 00:08:56,105
Finally, there is a desktop effects option.

150
00:08:56,353 --> 00:09:02,308
This enables some of the funky 3D and other enhanced features of the desktop.

151
00:09:02,449 --> 00:09:06,099
We will talk about that in another screencast.

152
00:09:08,354 --> 00:09:11,139
Also under Preferences, there is an option to set your default printer.

153
00:09:11,239 --> 00:09:15,099
So if there are numerous printers available to you, configured on this machine

154
00:09:15,252 --> 00:09:17,144
You can set whichever your default printer is.

155
00:09:17,297 --> 00:09:20,545
And you set up your printers in the Administration menu.

156
00:09:20,717 --> 00:09:24,654
We have talked in a previous screencast about how to setup printers.

157
00:09:24,826 --> 00:09:28,839
and we'll talk more about that in a subsequent screencast

158
00:09:29,125 --> 00:09:31,839
Another option down her is Preferred Applications.

159
00:09:32,030 --> 00:09:35,542
This is useful if you have a preference for an application,

160
00:09:35,642 --> 00:09:38,144
which is not one of the default ones supplied by Ubuntu.

161
00:09:38,259 --> 00:09:41,374
So for example if you want a different browser or a different email client

162
00:09:41,489 --> 00:09:42,769
or different media player,

163
00:09:42,869 --> 00:09:46,223
you can choose them in here, so that they open by default,

164
00:09:46,323 --> 00:09:51,235
instead of the applications that Ubuntu deliver.

165
00:09:56,165 --> 00:09:58,778
We also have configurable keyboard shortcuts

166
00:09:58,878 --> 00:10:02,447
many keyboards these days have a lot of extra buttons on them

167
00:10:02,547 --> 00:10:05,050
and you can configure some of those extra buttons to do things like 

168
00:10:05,150 --> 00:10:10,607
turn the volume up and down, play media, eject a CD and so on.

169
00:10:12,427 --> 00:10:14,390
There are also some standard keys on a keyboard,

170
00:10:14,490 --> 00:10:17,834
which we might want to configure various actions

171
00:10:18,045 --> 00:10:22,268
for example we've got here show the run dialog

172
00:10:22,368 --> 00:10:24,748
and show the panel menu are Alt + F2 and Alt + F1.

173
00:10:24,867 --> 00:10:28,937
If I hit Alt + F1 now, the Application menu appears

174
00:10:29,242 --> 00:10:32,682
So that's configurable, I have it configured to Alt + F1

175
00:10:33,103 --> 00:10:35,568
In addition, if I press the Print Screen button

176
00:10:35,816 --> 00:10:38,358
it takes a screenshot of the desktop.

177
00:10:39,084 --> 00:10:42,829
And if I choose Alt + Print, it takes a screenshot of the window.

178
00:10:43,001 --> 00:10:46,188
So I'll get a screenshot of just this window we're looking at now.

179
00:10:46,288 --> 00:10:47,984
There we go.

180
00:10:48,084 --> 00:10:50,186
So it's just that window.

181
00:10:50,377 --> 00:10:54,428
And you can configure these just by clicking on them.

182
00:10:55,670 --> 00:10:59,320
We also have an option here for removable drives and media

183
00:10:59,817 --> 00:11:03,812
and this tells Ubuntu what to do when it discovers removable media.

184
00:11:03,926 --> 00:11:06,102
So what happens when you insert a removable CD,

185
00:11:06,202 --> 00:11:09,386
what happens when you insert a USB key

186
00:11:09,486 --> 00:11:12,888
or an MP3 player, sorry media player,

187
00:11:13,136 --> 00:11:16,614
into your Ubuntu system

188
00:11:16,901 --> 00:11:21,391
There is also what to do when you insert blank CDs and DVDs

189
00:11:21,525 --> 00:11:25,404
and there's a couple of options here, there's Serpentine that you will find over here,

190
00:11:25,519 --> 00:11:28,992
it's the audio CD creator so you can drag music into Serpentine

191
00:11:29,092 --> 00:11:31,825
and burn that to a disk.

192
00:11:31,997 --> 00:11:35,494
And the other option is to use this CD burner I mentioned earlier

193
00:11:35,594 --> 00:11:38,642
where you can drag other files in here, data

194
00:11:38,742 --> 00:11:42,220
or make a data CD or DVD.

195
00:11:42,488 --> 00:11:46,501
Here we have what to do when someone inserts an Audio CD

196
00:11:46,692 --> 00:11:48,679
and that will run Sound Juicer.

197
00:11:48,779 --> 00:11:52,539
Which enables you to play and extract the audio from a CD.

198
00:11:53,112 --> 00:11:55,955
For video it uses Totem, which is the Movie Player.

199
00:11:56,055 --> 00:11:59,127
And for portable music devices it uses Rhythmbox.

200
00:11:59,227 --> 00:12:04,043
So that's so you can synchronize your audio to your portable music player.

201
00:12:04,310 --> 00:12:08,515
If you've got a digital camera, there's a manager that pops up

202
00:12:08,648 --> 00:12:10,674
and asks if you want to import your photos.

203
00:12:10,774 --> 00:12:15,924
And if you have a PDA, you can synchronize with Palm and Pocket PC devices.

204
00:12:16,062 --> 00:12:19,230
There's a nice little panel applet which you'll find

205
00:12:19,330 --> 00:12:22,196
if you right-click the panel and choose Add... and scroll down the bottom,

206
00:12:22,296 --> 00:12:27,337
you can see the Pilot Applet is for synchronizing to PDAs,

207
00:12:27,437 --> 00:12:30,279
Palm compatible PDAs.

208
00:12:31,369 --> 00:12:35,286
We can also automatically install printers when they are plugged in.

209
00:12:35,424 --> 00:12:39,031
So if you have a USB printer and you plug it in, if you tick this box

210
00:12:39,203 --> 00:12:43,121
then it's the equivalent of you going through this menu, System | Administration | Printing

211
00:12:43,274 --> 00:12:46,025
to actually install and configure the printer.

212
00:12:46,197 --> 00:12:48,185
And similarly when a scanner is connected

213
00:12:48,285 --> 00:12:52,140
you can run SANE, which you usually find under the Graphics menu.

214
00:12:52,389 --> 00:12:55,675
And SANE is the scanner interface,

215
00:12:55,775 --> 00:13:00,434
allows you to do test scans and scan images from a scanner

216
00:13:00,606 --> 00:13:02,860
And there's some other options for what to do when you

217
00:13:02,960 --> 00:13:06,625
plug in some other input devices.

218
00:13:09,338 --> 00:13:14,264
We also have a Power Management section under the Preferences menu

219
00:13:14,574 --> 00:13:18,109
and this really makes more sense if you've got a battery operated machine.

220
00:13:18,209 --> 00:13:23,326
There's more options for tuning if it's a laptop for example

221
00:13:24,052 --> 00:13:28,982
We can set here what to do when the power button is pressed.

222
00:13:29,116 --> 00:13:33,048
So when you press the power button it's the equivalent of pressing this icon on the toolbar here.

223
00:13:33,148 --> 00:13:35,210
This dialog box comes up,

224
00:13:35,310 --> 00:13:39,488
So where it says 'When the power button is pressed, Ask me',

225
00:13:39,588 --> 00:13:42,741
it means this dialog will appear.

226
00:13:43,391 --> 00:13:47,208
Also, if your PC has a Suspend button you can choose what to do.

227
00:13:47,308 --> 00:13:50,060
Suspend means save the computer state to memory.

228
00:13:50,160 --> 00:13:53,304
Hibernate means save the computer state to disk.

229
00:13:53,404 --> 00:13:56,805
Saving to disk means you can unplug the power

230
00:13:57,016 --> 00:14:01,411
Suspend requires some power, but for a laptop it will obviously have a battery.

231
00:14:01,755 --> 00:14:04,392
There is also this icon on the toolbar you can choose to display

232
00:14:04,492 --> 00:14:07,430
It doesn't really make any sense with this PC because it's a desktop

233
00:14:07,545 --> 00:14:09,857
and not a laptop, so there's not much point in me displaying that

234
00:14:09,957 --> 00:14:13,946
because it will always be plugged in when it's switched on.

235
00:14:16,985 --> 00:14:21,494
We can also configure network proxy, this is useful if you're on a corporate network

236
00:14:21,594 --> 00:14:23,883
or even a home network the has a proxy server.

237
00:14:23,983 --> 00:14:27,304
You can configure there the address of your proxy server,

238
00:14:27,404 --> 00:14:32,730
useful if you have to use that to get out on to the web.

239
00:14:34,355 --> 00:14:37,622
We can also configure the screen resolution

240
00:14:37,813 --> 00:14:40,546
So there's a little drop down list here with screen resolution

241
00:14:40,646 --> 00:14:44,578
and the refresh rate which is important for Cathode Ray Tube monitors.

242
00:14:44,769 --> 00:14:48,969
And there's also a Rotation option, which is useful if you've got a monitor that can be rotated.

243
00:14:49,069 --> 00:14:52,852
Or if maybe you've got a tablet PC, which can be rotated as well.

244
00:14:52,952 --> 00:14:57,840
And then you can choose to make this the default resolution for everyone on this PC

245
00:14:58,126 --> 00:15:02,942
We'll talk more about screen resolution on a later screencast

246
00:15:03,592 --> 00:15:06,840
There's a load of screensavers supplied with Ubuntu.

247
00:15:07,146 --> 00:15:09,878
As you can see, quite a few and I'll just pick one randomly.

248
00:15:10,108 --> 00:15:12,420
You can see, you get a preview in that window.

249
00:15:12,520 --> 00:15:16,165
If you get press the preview button below, you get a full screen preview.

250
00:15:16,395 --> 00:15:19,605
You can pick and choose any screensaver you like

251
00:15:20,350 --> 00:15:24,612
And will use that as your screensaver, whichever one you choose.

252
00:15:25,242 --> 00:15:27,531
As you can see there is an awful lot of them.

253
00:15:27,631 --> 00:15:30,225
And right at the top of the list you can also just choose random,

254
00:15:30,325 --> 00:15:32,939
and it will pick a screensaver randomly

255
00:15:33,039 --> 00:15:35,843
each time the screensaver kicks in you'll get a random screensaver.

256
00:15:35,943 --> 00:15:39,345
You can change the interval after which the screensaver kicks in.

257
00:15:39,517 --> 00:15:43,358
and you can also choose to lock the screen, so it asks you for your password

258
00:15:43,740 --> 00:15:46,358
when the screensaver kicks in

259
00:15:46,472 --> 00:15:48,589
and someone moves the mouse or touches the keyboard

260
00:15:48,689 --> 00:15:51,517
you can force it to ask you for a password.

261
00:15:51,842 --> 00:15:56,505
There's also a power management option that takes us to where we've just seen.

262
00:16:03,479 --> 00:16:06,136
Let's have a look at the windows preferences.

263
00:16:06,480 --> 00:16:09,422
Now this is an option that I personally quite like.

264
00:16:09,522 --> 00:16:12,652
But I know some people don't like it, it's not familiar.

265
00:16:12,752 --> 00:16:15,881
Let's open a couple of windows and see what this does.

266
00:16:16,263 --> 00:16:19,015
If I just open the calculator and the dictionary

267
00:16:19,206 --> 00:16:21,533
Now if I move these around a little bit,

268
00:16:21,633 --> 00:16:24,671
With that first option ticked in the window preferences.

269
00:16:24,882 --> 00:16:28,359
What'll happen is as I move the mouse over a window, it highlights the window.

270
00:16:28,459 --> 00:16:32,124
it makes it the active window, I don't have to click on the window at all.

271
00:16:32,224 --> 00:16:35,506
All I am doing is moving the mouse over the window, I'm not clicking it at all.

272
00:16:35,793 --> 00:16:39,443
So all I'm doing is moving the mouse and it becomes highlighted.

273
00:16:40,628 --> 00:16:43,972
In addition there is a 'Raise selected window after a given interval' option.

274
00:16:44,163 --> 00:16:48,061
And if we turn that on, let me just rearrange these windows so they're on top of each other.

275
00:16:48,161 --> 00:16:50,732
If you turn this on then after a half second delay

276
00:16:50,832 --> 00:16:53,373
it will bring the window to the front without clicking on the window

277
00:16:53,473 --> 00:16:56,698
So it's quite useful to just nudge the mouse over a window

278
00:16:56,798 --> 00:17:00,520
without having to actually physically press the mouse button.

279
00:17:01,074 --> 00:17:05,178
Some people prefer it, I prefer to just have it

280
00:17:05,278 --> 00:17:08,412
activate the window and not actually bring it to the front.

281
00:17:08,852 --> 00:17:11,756
You can also choose what to do when someone double-clicks the title bar.

282
00:17:11,928 --> 00:17:15,463
So by default it's maximize, but you can also make it roll up,

283
00:17:15,563 --> 00:17:17,451
so all you see is the title bar.

284
00:17:17,551 --> 00:17:21,846
This window can't be maximized, so it won't work for this window.

285
00:17:22,400 --> 00:17:25,400
There is also an option for the movement key, if you grab the Alt key

286
00:17:25,500 --> 00:17:28,339
in this particular case and grab hold of the window,

287
00:17:28,439 --> 00:17:31,109
you can move any window around using that combination of 

288
00:17:31,209 --> 00:17:35,088
Alt key and click the mouse.

289
00:17:40,477 --> 00:17:44,662
We also have the option of setting keyboard repeat delay.

290
00:17:44,762 --> 00:17:49,478
So for example the speed at which those letter Os appear there,

291
00:17:49,669 --> 00:17:52,229
is configured by the options at the top of that window.

292
00:17:52,401 --> 00:17:54,575
We can also set the keyboard layout.

293
00:17:54,675 --> 00:17:57,523
So the default here is U.S. English, which is wrong for my keyboard.

294
00:17:57,623 --> 00:18:00,312
So we can change that just by clicking Add

295
00:18:00,412 --> 00:18:03,117
and choose the more appropriate layout.

296
00:18:03,217 --> 00:18:07,803
I've got a UK keyboard, so if I scroll down and find United Kingdom.

297
00:18:07,903 --> 00:18:11,066
There are a number of variants, but I am just going to just the default variant

298
00:18:11,166 --> 00:18:14,740
because I don't have a Dvorak keyboard or any other wacky layout.

299
00:18:14,988 --> 00:18:18,523
I'll set that to be the default and then remove the other layout.

300
00:18:18,623 --> 00:18:22,647
because I don't need that. And now I've set my keyboard layout.

301
00:18:22,766 --> 00:18:24,772
There's a little bug in this part of the window,

302
00:18:24,872 --> 00:18:27,791
which I'm sure will disappear before this is released.

303
00:18:28,002 --> 00:18:31,384
And these are some options for customizing your keyboard layout.

304
00:18:31,957 --> 00:18:35,067
For example some people don't like the Caps Lock key at all.

305
00:18:35,167 --> 00:18:38,431
They think it's redundant and so here you can configure the Caps Lock key

306
00:18:38,531 --> 00:18:41,378
to do something other than be Caps Lock.

307
00:18:41,588 --> 00:18:44,741
Which is quite a useful feature.

308
00:18:45,333 --> 00:18:48,467
And the final tab is the Typing Break tab.

309
00:18:48,716 --> 00:18:55,495
Where if you switch this on, you can enforce Ubuntu to coerce you to take a break.

310
00:18:55,595 --> 00:18:59,226
and you get this little timer appear in the panel at the top of the screen

311
00:18:59,417 --> 00:19:03,659
and you can configure the limit, so you can try and get it to give you a break every

312
00:19:03,831 --> 00:19:06,808
however many minutes you choose, every six minutes would be nice,

313
00:19:06,908 --> 00:19:11,700
but generally you would set to something a bit more appropriate

314
00:19:11,800 --> 00:19:15,239
like maybe an hour or less, or more it's entirely up to you.

315
00:19:15,583 --> 00:19:18,717
And then it will lock the screen

316
00:19:18,817 --> 00:19:23,131
you can skip the typing break if you're in the middle of something

317
00:19:23,231 --> 00:19:29,800
you can skip it, but it's quite a nice feature to enable you to force-ably take a break

318
00:19:29,900 --> 00:19:34,501
and it counts down and you see that color bar fill up as the time passes.

319
00:19:41,094 --> 00:19:44,686
The final one we will take a look at is the remote desktop

320
00:19:45,489 --> 00:19:49,803
Remote desktop is very useful for someone else to provide support to you.

321
00:19:49,960 --> 00:19:53,687
If they want to or if you would like them to remotely control your desktop.

322
00:19:53,878 --> 00:19:59,266
You can set it here to force them to use a password in order to remotely control your desktop.

323
00:19:59,916 --> 00:20:04,995
And the is a remote control program under the Applications menu, in Internet,

324
00:20:05,114 --> 00:20:09,528
you'll find there is a remote client so you can remotely control other PCs as well.

325
00:20:12,031 --> 00:20:15,815
Let's take a look at some of the options under the Administration menu.

326
00:20:16,770 --> 00:20:19,694
Now these options are making changes to the whole system.

327
00:20:19,794 --> 00:20:22,427
So it asks you for your password to make sure you are allowed

328
00:20:22,527 --> 00:20:24,983
to make changes to the system.

329
00:20:25,083 --> 00:20:27,682
So I'll type in my password.

330
00:20:28,045 --> 00:20:30,625
And the option I chose was Software Sources

331
00:20:30,725 --> 00:20:33,357
and this is where Ubuntu gets it's software updates from.

332
00:20:33,529 --> 00:20:36,548
You can get your software updates on a CD-ROM or you can get

333
00:20:36,663 --> 00:20:39,262
your software updates more commonly over the Internet.

334
00:20:39,415 --> 00:20:42,162
And this is closely linked to the Update Manager,

335
00:20:42,262 --> 00:20:46,046
which is also in the Administration menu.

336
00:20:46,275 --> 00:20:50,097
And here the Update Manager is checking those sources

337
00:20:50,345 --> 00:20:55,371
that are listed in the Software Sources application, to find out what updates there are.

338
00:20:55,638 --> 00:20:59,288
And there are a number of sets of updates that you can apply.

339
00:20:59,498 --> 00:21:02,307
And here we don't have any updates that are required.

340
00:21:02,479 --> 00:21:04,653
We'll talk more about updating the system,

341
00:21:04,753 --> 00:21:07,811
we'll have a whole screencast about that later.

342
00:21:09,340 --> 00:21:11,862
Another useful tool is the System Log.

343
00:21:12,072 --> 00:21:15,512
System Log is useful when trying to diagnose problems with your system.

344
00:21:15,856 --> 00:21:18,206
There are a number of these

345
00:21:18,306 --> 00:21:21,321
somewhat difficult to understand log files.

346
00:21:21,421 --> 00:21:26,691
But usually a developer or an expert can what the messages mean.

347
00:21:26,920 --> 00:21:32,576
And so sometimes someone might ask you to copy and paste chunks out of a particular log file.

348
00:21:32,729 --> 00:21:36,761
And here's how you get to the main log files for your system

349
00:21:36,895 --> 00:21:42,456
and you can copy and paste those into a email or a support forum, for example.

350
00:21:43,659 --> 00:21:48,914
So it's called System Log, but there are numerous log files in there.

351
00:21:49,086 --> 00:21:52,259
But they are system wide log files.

352
00:21:53,004 --> 00:21:55,751
There's also some configuration options for the network

353
00:21:55,851 --> 00:21:58,560
Now you'll notice with each of these, it's not asking me for a password again.

354
00:21:58,660 --> 00:22:03,223
It asked me for the very first application I opened for a password,

355
00:22:03,323 --> 00:22:09,438
but the subsequent ones it didn't because I've typed my password in within a certain few  minutes.

356
00:22:09,667 --> 00:22:14,540
Here we can configure the network, so I have a wired connection to my network.

357
00:22:14,673 --> 00:22:19,370
and I can configure that to automatically connect and get an IP address from my network,

358
00:22:19,604 --> 00:22:23,192
We'll talk more about networking in a subsequent screencast

359
00:22:23,292 --> 00:22:25,317
That's a bit too much for this one.

360
00:22:25,417 --> 00:22:29,999
Here we can set my hostname, which is the name my computer is known as on the network.

361
00:22:30,247 --> 00:22:33,114
And once we've configured our network, there are some network tools,

362
00:22:33,214 --> 00:22:37,299
that we can use to diagnose network problems.

363
00:22:37,623 --> 00:22:42,320
Common tools that we might use are Ping, Traceroute and lookup

364
00:22:42,420 --> 00:22:46,089
for example to validate that the physical network works

365
00:22:46,189 --> 00:22:49,108
and we're able to send packets over the network.

366
00:22:49,208 --> 00:22:53,943
and we're able to lookup hostnames and all these other kind of 'networky' type things.

367
00:22:55,051 --> 00:22:58,964
Again they are useful in a support point of view, if someone wants you to try something out

368
00:22:59,064 --> 00:23:02,293
you can do so through that application.

369
00:23:02,733 --> 00:23:05,943
We also have the GDM setup that I mentioned earlier,

370
00:23:06,043 --> 00:23:08,141
this is the log in window configuration.

371
00:23:08,241 --> 00:23:13,926
So the log in window is usually the first screen you see when you boot up your Ubuntu system.

372
00:23:14,026 --> 00:23:17,638
It asks you for your username and password and you can change the theme

373
00:23:17,848 --> 00:23:20,691
There's a number of themes installed and you can add additional themes

374
00:23:20,791 --> 00:23:22,984
they're downloadable from the Internet.

375
00:23:23,084 --> 00:23:26,160
And you can see there are a few themes delivered.

376
00:23:26,260 --> 00:23:29,868
And you can choose to have a random one from that set.

377
00:23:29,968 --> 00:23:36,322
So you see the little tick marks here, you tick all the ones that you want to be used when you log on

378
00:23:36,422 --> 00:23:39,097
or you can just choose one.

379
00:23:41,582 --> 00:23:44,238
There's also some security options

380
00:23:44,448 --> 00:23:48,132
We have to be careful with these because this one for example enables automatic log in,

381
00:23:48,232 --> 00:23:52,393
which means it's very useful in that it won't ask you for a password,

382
00:23:52,493 --> 00:23:54,743
as soon as you boot up it will log straight in as that user.

383
00:23:54,843 --> 00:23:59,449
Or alternatively, this is what I use on my daughter's PC, I have a timed log in,

384
00:23:59,549 --> 00:24:03,041
so if she doesn't do anything for thirty seconds, it will just log her on to the desktop.

385
00:24:03,141 --> 00:24:08,621
But if I want to log on, I can quite easily, so long as I do so before that thirty seconds is up.

386
00:24:10,169 --> 00:24:15,233
Loads of further options on that page, which we're not going to go into

387
00:24:17,851 --> 00:24:21,978
Also it's possible to remotely log on to your Ubuntu system

388
00:24:22,513 --> 00:24:28,203
and remotely log on to other Ubuntu systems, in fact and this allows us to configure

389
00:24:28,303 --> 00:24:33,597
what the log on screen looks like when we're logging on remotely

390
00:24:33,921 --> 00:24:37,605
Whether it's the same as the log on screen locally or different.

391
00:24:37,705 --> 00:24:41,336
We can have a different look and feel for remote users than local users for example.

392
00:24:41,641 --> 00:24:44,890
And the users that are listed in what's called the face browser.

393
00:24:45,100 --> 00:24:47,943
So some of these themes have a thing called a face browser,

394
00:24:48,043 --> 00:24:51,674
which is basically a list of users who could log on

395
00:24:51,903 --> 00:24:54,616
and it shows a little icon and their name.

396
00:24:54,960 --> 00:25:00,196
You can populate this list, which actually gets populated from the system

397
00:25:00,521 --> 00:25:06,158
list of users, which is this file that it mentions, /etc/passwd is a list of users.

398
00:25:06,521 --> 00:25:12,197
And if you look in the About Me, you can see that little icon appears in the face browser.

399
00:25:12,522 --> 00:25:15,751
So each person gets their own little icon and they can just click on that

400
00:25:15,851 --> 00:25:19,363
to log on and type in their password.

401
00:25:25,344 --> 00:25:28,210
We also have a neat System Monitor here.

402
00:25:28,344 --> 00:25:32,047
This is useful for figuring out if there's any processes,

403
00:25:32,147 --> 00:25:36,671
programs that are consuming too much of your CPU

404
00:25:36,771 --> 00:25:39,848
We can also see how much free disk space we have here.

405
00:25:39,948 --> 00:25:42,308
So I have a very small disk here.

406
00:25:42,408 --> 00:25:45,619
It's quite a useful system monitor.

407
00:25:46,727 --> 00:25:51,676
Okay, that's a review of some of the applications in the Preferences and Administration menu

408
00:25:51,886 --> 00:25:55,402
All the screencasts are available to download from our website,

409
00:25:55,502 --> 00:25:58,899
