The diff below adds support for ALPS touchpads to the pms(4) driver.
I'm looking for testers with or without ALPS hardware, especially if you
have a touchpad, to be sure it doesn't break anything.
Currently, ALPS DualPoint are untested and support for special buttons
(back, forward, etc) is missing because I don't have such hardware.
I use the following synaptics(4) configuration for edge scrolling and
simple left tapping:
xinput set-prop /dev/wsmouse0 "Synaptics Finger" 25 30 60
xinput set-int-prop /dev/wsmouse0 "Synaptics Tap Action" 8 0 0 2 3 1 0 0
xinput set-int-prop /dev/wsmouse0 "Synaptics Click Action" 8 1 0 0
xinput set-int-prop /dev/wsmouse0 "Synaptics Edge Scrolling" 8 1 0 0
Compared to the previous version, I left the Y-axis translation because
it's also needed for the COMPAT mode.
Comments?
