Download1 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 which is screencasts.ubuntu.com
