Oh for F!@#$%’s sake.
Another update to the xserver and my touchpad is broken. After googling for about 10 minutes, I come up with this thread from just a few days ago. Apparently udev configuration is out and the xorg.conf is back in.
This is definitely a weak point in open source stuff. Changes like this should be documented better or some kind of warning or explanation that current configuration techniques are about to be broken should be available.
I suppose this is what I get for using the ‘testing’ distro.
UPDATE:
Here’s the relevant section to add to xorg.conf:
Section "InputClass"
Identifier "Synaptics"
driver "synaptics"
MatchProduct "ETPS/2"
MatchDevicePath "/dev/input/event9"
Option "VertEdgeScroll" "1"
Option "MaxSpeed" "1"
Option "AccelFactor" "0.05"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
EndSection
See the InputClass section of the xorg.conf man page.
UPDATE II:
The two Match lines can be replaced with a MatchIsTouchpad "1" line. I don’t know if this is better or not- but it seems like it might be preferrable since InputClass sections are applied to anything that matches according to the man page. At least it’s limited to touchpads this way.
