For Newbies
On laptops, the [http://en.wikipedia.org/wiki/Touchpad touchpad] is the built-in mouse. "Synaptics touchpad" should not be confused with "Synaptic" - Ubuntu's Package Manager (Graphical User Interface for apt-get).
In Breezy(5.10), laptops with a synaptics touchpad should work out of the box. Go to a terminal and grep (look inside) your /etc/X11/xorg.conf file:
grep Id /etc/X11/xorg.conf
If one of the lines is:
Identifier "Synaptics Touchpad"
then you have a Synaptics Touchpad.
In Dapper flight 7 (6.06), synaptics touchpads seem to be misdetected as some kind of wacom device, so the scrollbar may not work. See - "Editing Your xorg.conf File to Include Synaptics Touchpad drivers" - for scrollbar support.
qsynaptics (or in KDE ksynaptics) is a GUI which allows you to configure your touchpad. At a terminal, enter:
sudo apt-get install qsynaptics
or:
sudo apt-get install ksynaptics
You may need to run qsynaptics -r each time you restart X. Go to System>Preferences>Sessions>Startup Programs> and add it.
Dapper: Editing Your xorg.conf File to Include Synaptics Touchpad
In order to get scrollbar support, you may need to edit your xorg.conf file. In a terminal, type: gksudo gedit /etc/X11/xorg.conf After the lines:
Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" Option "Device" "/dev/input/mice" Option "Protocol" "ExplorerPS/2" Option "ZAxisMapping" "4 5" Option "Emulate3Buttons" "true" EndSection
add the following:
Section "InputDevice" Identifier "Synaptics Touchpad" Driver "synaptics" Option "SendCoreEvents" "true" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "HorizScrollDelta" "0" Option "SHMConfig" "on" EndSection
there are also a bunch of lines about a wacom tablet, I have commented them out, I am not sure if that is a necessary step. -brallan
next, find the bit near the bottom where it says:
Section "ServerLayout" Identifier "Default Layout" Screen "Default Screen" InputDevice "Generic Keyboard" InputDevice "Configured Mouse" InputDevice "stylus" "SendCoreEvents" InputDevice "cursor" "SendCoreEvents" InputDevice "eraser" "SendCoreEvents" EndSection
and add the following line after the "Configured Mouse" line:
InputDevice "Synaptics Touchpad"
i also commented out the three lines about the wacom: "stylus", "cursor", and "eraser", but I am not sure if this is necessary. -brallan.
restart X: <ctrl> <Backspace> and you should now have scrollbar support. Install qsynaptics for fine control over the device.
Turning Synaptics Touchpads On/Off with a shortcut key
You may wish to turn the touchpad on or off so that it doesn't interfere with typing when using a USB or other mouse.
Use following steps:
Step 1
from a terminal, edit /etc/xorg.conf
gksudo gedit /etc/X11/xorg.conf
and look for the following section of code:
Section "InputDevice" Identifier "Synaptics Touchpad" Driver "synaptics" Option "SendCoreEvents" "true" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "HorizScrollDelta" "0" EndSection
and add one more Option at the End of the Section:
Option "SHMConfig" "on" EndSection
If you are using an Alps-Touchpad, which you can find out by typing
cat /proc/bus/input/devices
your code section should look like this
Section "InputDevice" Driver "synaptics" Identifier "TouchPad" Option "SendCoreEvents" "true" Option "Device" "/dev/input/event2" Option "Protocol" "event" Option "SHMConfig" "on" EndSection
You can define some parameters which influence the behaviour of your touchpad. These parameters are presented already in [https://wiki.ubuntu.com/SynapticsTouchpadWartyHowto?highlight=%28touchpad%29]. You can check if your touchpad works correct and you have the correct parameters with
synclient -m l
If everything works fine, the position of your finger will be updated everytime you move it and based on this information you can set your parameters.
Step 2
Next we will create 3 files - a bash script to turn the touchpad on, one to turn it on, and a python script to use a single key combination for both. At a terminal, cd to /usr/local/bin and make a new file:
cd /usr/local/bin gksudo gedit tpoff
and paste the following code in the file, save it and close it.
# synclient touchpadoff=1
again, make a new file:
gksudo gedit tpon
paste the following, save and close:
# synclient touchpadoff=0
once again, make a new file:
gksudo gedit touchpad.py
paste the following, save and close
import os import string def ReadFile(): myfile = open('/tmp/synclient.tmp', 'rb') for line in myfile: TestString(line) myfile.close() def TestString(string): for word in string.split(): if word == "TouchpadOff": setting = string.split() ChangeState(setting[2]) def ChangeState(current): if current == "0": os.system("synclient touchpadoff=1") else: os.system("synclient touchpadoff=0") os.system("rm /tmp/synclient.tmp") def Main(): ReadFile() os.system("synclient -l > /tmp/synclient.tmp") Main()
and finally, change the permissions of these three files:
sudo chmod 777 tpon tpoff touchpad.py
Step 3
Next, edit your sudoers files to allow you to execute both scripts without a password.
sudo visudo
and add this line
{user} ALL = NOPASSWD: /usr/local/bin/touchpad.py
where {user} is your user name
save (in nano hit <CTRL> <o>), and make sure to save it as: /etc/sudoers
Step 4
Alternatively to setup bellow, you might use [https://help.ubuntu.com/community/MultimediaKeys gnome-keybindings](In depth instructions, 4.) or other desktop-dependent tool.
Next, install xbindkeys
sudo apt-get install xbindkeys
when it's done, install xbindkeys-config, the GUI for xbindkeys
sudo apt-get install xbindkeys-config
once each is installed, start both applications:
xbindkeys
and
xbindkeys-config
edit your file to the shortcut key you want. For example, to be able to switch the touchpad on/off by <Ctrl><F5>, fill in the following, under Edit:
Name: Touchpad On/Off Key: Control + F5 | m:0x4 + c:71 Action: /usr/local/bin/touchpad.py
then click apply & save & exit
Now that that is done, restart xbindkeys:
xbindkeys
You may need to restart X.
Remember that each time you restart X, you will need to run xbindkeys again in order for the shortcut to work. Go to System>Preferences>Sessions>Startup Programs> and add it.
Apple ibook G4
With a fresh install of Dapper the touchpad works extremely slow. The bug has been filed here: [https://launchpad.net/distros/ubuntu/+bug/28495] The fix is pretty simple. Put the following configuration into your /etc/X11/xorg.conf in the appropriate place and then restart X.
