How to disable a feature in a driver or disable a certain driver all together?

theif519 · 07-04-2011, 01:00 PM

For instance, the one thing I hated more than anything, was the touch-pad on here, and I mean whenever you touched it it counted as a mouse click. I always hated it and in Windows I found a way to disable it with disabling the entire mouse pad, how do I do the same in Ubuntu? In every other distribution I didn't have to worry about it, but I suppose that I'm using the proprietary drivers or something.

Anyway, TL;DR: How do I disable a touch pad feature

Use your xorg configuration files. For example, for my Synaptics touchpad I have the following file, named 50-synaptics.conf, in the folder /etc/X11/xorg.conf.d

Code:

# Use "synclient -l" to see all available options
# Use "man synaptics" for details about what the options do
#
Section "InputClass"
	Identifier "touchpad"
	Driver "synaptics"
	MatchDevicePath "/dev/input/event*"
	MatchIsTouchpad "on"
	Option "TapButton1" "1"
	Option "TapButton2" "0"
	Option "TapButton3" "0"
	Option "VertEdgeScroll" "1"
	Option "HorizEdgeScroll" "1"
	Option "MinSpeed" "1.1"
	Option "MaxSpeed" "1.9"
EndSection

As you can see I have disabled the middle and right mouseclick with the TapButton options. For the single click you have to use TapButton1, just set the option to 0. This way the touchpad will work normal, but just don't click anymore.
For more options that can be used in that file have a look at

Code:

synclient -l

.
Remember, this all is for Synaptics touchpads, I don't know how to configure other touchpads.

How do I edit the file? I can't find the first file you suggested.

The file is not there by default. Either you copy that section to your existing /etc/X11/xorg.conf or you create the folder /etc/X11/xorg.conf.d and then create that file in it.
Both solutions should work.
