[Solved?] Suspend:Two finger scroll stops working

[Hallvor]

I have the same problem as described here:

I noticed that when I suspend my laptop by closing the lid, my two-finger vertical scroll stops working on my touchpad.

When I reboot my laptop (with sudo reboot) my vertical scroll works again. I think something goes wrong when my laptop exits suspend mode.

EDIT: Ok, so very mysteriously, after waking from sleep the touchpad will respond to three-finger vertical scroll instead of two-finger vertical scroll.

Systemsettings says two finger vertical scroll is enabled.

I don't have much to offer here, but any ideas?

Which touchpad driver are you using?

Check with

Code: Select all

synclient

^ That will only work if you're using xserver-xorg-input-synaptics.

[Hallvor]

Code: Select all

hallvor@debian-thinkpad:~$ kcm-touchpad-list-devices | grep TOUCHPAD
Name: SynPS/2 Synaptics TouchPad Type: TOUCHPAD Use: Extension Pointer

Code: Select all

hallvor@debian-thinkpad:~$ synclient
bash: fant ikke kommando synclient

It says no such command.

Code: Select all

$ cat /proc/bus/input/devices

So it's libinput then. Which desktop is this?

Check the output of

Code: Select all

libinput list-devices 

for both your normal desktop and when you're experiencing the problem to see if there's any difference.

You could try the synaptics driver, see if that behaves any better:

Code: Select all

# cp /usr/share/X11/xorg.conf.d/70-synaptics.conf /etc/X11/xorg.conf.d/

Log out & back in again to test. Remove /etc/X11/xorg.conf.d/70-synaptics.conf to revert to the stock behaviour.

Thanks, but libinput gives no wanted output (no such command).

I'll test your suggestion.


Edit:
I had to install xserver-xorg-input-synaptics before copying the file, rebooting, suspending and waking up from suspend. It works well for now, so we'll see if it continues.
