I have a ThinkPad x220 which has a buttonless touchpad. I installed xf86-input-synaptics-clickpad 1.4.1-3 from AUR which makes both buttons work but I don't like some of the defaults that it sets. Below shows the properties that are set after reboot.
$ xinput list-props 'SynPS/2 Synaptics TouchPad'

I would like to set 'Synaptics LED Dobule Tap' to zero because I don't have a LED and I do have a keyboard key (which is working just fine). I would also like to set the area because the defaults assumes that the button area is too big. I can set the paramiters with xinput just fine but then they are not remembered after reboot. I know that I could write a script that gets run at the appropriate time to set things but that seems unclean so I made a file called /etc/X11/xorg.conf.d/20-clickpad.conf with the folowing contents:
Section "InputClass"
Identifier "Touchpad Settings"
MatchProduct "SynPS/2 Synaptics TouchPad"
MatchDevicePath "/dev/input/event*"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
Option "TapAndDragGesture" "off"
Option "PalmDetect" "on"
Option "LEDDobuleTap" "false"
Option "BottomEdge" "4540"
EndSection
the only problem is that it doesn't work. Is there a way to set parameters with xorg.conf that you can set with xinput? it seems like I should be able to.
thanks
[Edit] after reading the man page and fixing my file I was able to fix the area issue but LEDDoubleTap is still on
