[SOLVED]Touchpad hasn't worked since installation

Bumble · 2018-03-11 20:36:09

Ever since installation on this machine I haven't been able to get the touchpad to work, a mouse works fine but I'd like to get it working regardless.

Related packages installed
libinput, xf86-input-libinput, xf86-input-evdev

This is on an acer aspire v15 nitro VN7-591G.

I find the spaces before the actual naming ' Touchpad' under xinput to be a bit weird but I wouldn't expect this to do anything out of the ordinary. This is one of those precision touchpads that microsoft tried adopting I believe, not sure if that's relevant.

I've tried messing with the xinput options for the touchpad and the numbers don't seem to make any differences. The output of libinput list-devices seems strange to me but I don't know how to actually change those, I was under the impression those were controlled through the numbers modified in xinput set-prop, but I can't seem to change any of its output.

Any ideas on getting this to work?

"Does not work" is not a very good error description. Does it create events in "libinput-debug-events" and "xinput test 11"?

Does it help if you remove libinput and try using evdev? You could also try adding a 30-touchpad.conf inside your /X11/xorg.conf.d manually specifing "Driver" "evdev".

Indeed. By looking at mine, which looks like

Device 'SynPS/2 Synaptics TouchPad'

makes me think that libinput recognizes the device as a generic "Touchpad" but it's missing the necessary information to handle the device. Figures, if this is designed to work as a "Microsoft Fancy Touchpad".

My apologies, no output whatsoever from either of those.

I hadn't seen any

So this is what I tried throwing together:

Section "InputClass"
    Identifier "    Touchpad"
    Driver "evdev"
    MatchIsTouchpad "on"
    "Tapping" "on"
    "ClickMethod" "clickfinger"
    "NaturalScrolling" "false"
EndSection

tried siwtching the driver to "libinput" as well but I couldn't get any output in xinput test 11, or libinput-debug-events

Restarting X should be enough to get this to work, if it would work, correct?

Means it doesn't generate events on the kernel layer. Based on lo1's comment, try "psmouse.synaptics_intertouch=0" as kernel parameter. (But ensure psmouse is actually loaded, "lsmod | grep psmouse")

I tried this despite it not being a synaptics touchpad(to the best of my knowledge) and despite xf86-input-synaptics no longer being worked on and got no difference.

Touchpad still not working.

seth · 2018-03-11 23:24:25

(Just for completeness sake: the parameter is rather new, the name is somewhat misleading and this is not related to xf86-input-synaptics)

Ruling out the obvious: Fn+F7 has no impact either?

Bumble · 2018-03-11 23:38:32

Confirmed I'm an idiot Fn + F7 just solved my problem
Didn't even realize it had that functionality despite the icons being right on the F-keys. (I didn't know that one in particular was a touchpad lock).

Many thanks.
