1. Open a terminal
2. Type:
Code:
sudo gedit /etc/X11/xorg.conf
3. You will be prompted for your password. Enter it.
4. gedit will now open. You should scroll down until you see a section that looks somewhat like this:
Code:
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizScrollDelta" "0"
EndSection
5. What we need to do is add a couple of options. We will add one for MinSpeed, one for MaxSpeed and one for AccelFactor. The values that you give these options will determine the sensitivity of your touchpad. Here is my /etc/X11/xorg.conf entry for the touchpad:
Code:
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizScrollDelta" "0"
Option "MinSpeed" "0.5"
Option "MaxSpeed" "0.5"
# Option "AccelFactor" "0.0010"
EndSection
6. You can play with different values for MinSpeed, MaxSpeed and AccelFactor but keep in mind that they must be floating point values (decimal numbers) and that an entry of 1.0 is very fast! If you want acceleration then set the MinSpeed lower than the MaxSpeed and play with different values for AccelFactor.
If you do not want acceleration then make your MinSpeed and MaxSpeed the same. (For good measure you can see that I have also commented out the AccelFactor option. Whenever you see a line with a # at the start of it that means that the rest of that line will be ignored by the system as a 'comment'.)
7. Now you need to save the changes you have made to /etc/X11/xorg.conf and then close the file and reboot.
8. Once you reboot try your new touchpad settings and make further adjustments to the /etc/X11/xorg.conf file until you have the perfect settings for you.
