Can't Use Trackpad in GUI Even Though It's Detected

brando56894 · 2015-04-30 19:26:43

I have Arch installed on my HP Pavilion Chromebook (not the HP 14) and my touchpad doesn't move the cursor at all so I stuck using a mouse. I was worried that I may have damaged it since I have taken the chromebook apart a few times in order to upgrade it. I also thought that maybe the drivers weren't loaded but that doesn't seem to be the case since it's listed in /proc/bus/input/devices

Here's the output

I: Bus=0018 Vendor=0000 Product=0000 Version=0001
N: Name="Cypress APA Trackpad (cyapa)"
P: Phys=i2c-0-0067/input0

B: PROP=1
B: EV=b
B: KEY=e520 30000 0 0 0 0
B: ABS=660800001000003

I know the device itself works because I have used evtest /dev/input/input14 to verify the touches. X also detect the device because it says so in the logs.

So if the drivers are loaded and it's detected by the X Server, why doesn't it work at all in KDE?

Edit: This doesn't seem to be specific to KDE since I just tested an X session with TWM and it didn't work in there either.

Have you installed xf86-input-synaptics?

brando56894 · 2015-04-30 19:45:14

I didn't have it installed so I installed it and restarted X but that didn't change anything.

I managed to get it working (mostly) by copying the config file in the wiki and then I had to lower the touch sensitivity in KDE because it was only detecting certain touches and it was really jagged. Two finger scrolling works, but I can't seem to get tap-clicking to work.

Here's my /etc/X11/xorg.conf.d/50-synaptics.conf but it seems the settings in the touchpad module in System Settings seem to override that, except for the tapping.
