Clickpad Recognised By Live USB But Not After Installation

simonw · July 5, 2021, 9:31pm

I have a StarLabs LabTop IV which has a buttonless touchpads/clickpad. When I boot into the current live environment on a USB stick I can configure it to do things like have a two-finger click (not tap) to emulate a right-click and can click with one finger and drag with another which I find much easier than clicking and dragging with a single finger. However when I install a desktop environment or a window manager plus LightDM it seems not to be recognised as a clickpad any more and libinput doesn’s support the options to make the changes I mentioned above.

In both environments, if I run sudo libinput list-devices I get the following error at the top of the output:

event9 - PCT1336:00 093A:1336 Touchpad: kernel bug: clickpad with right button, assuming it is not a clickpad

The output of xinput --list-props for the live USB environment is:

Does anyone have any idea why the live environment detects the clickpad differently and how I can fix it in the installed environment?

Not sure if related, but I just lost all functionality of my touchpad. I can still switch it on/off using the hotkeys I assigned to that toggle, sudo libinput list-devices and xinput --list-props output (see below) lead me to believe the thing does still exist, but the pointer on my screen simply refuses to move, nor does anything scroll anymore. My next move was indeed going to be trying the live USB, which I’ll try next and report.

I think your problem might be different (and more severe!) because my clickpad is found and works but in a more limited way in the installed version of EndeavourOS.

ReemZ · July 6, 2021, 10:35am

Sorry I couldn’t be of more help mate

simonw · July 6, 2021, 10:43am

I hope you get to the bottom of your problem too. If I come across anythingvwhich looks like it might fix your issue I’ll give you a shout.

simonw · July 7, 2021, 11:50am

Just adding that I get this on a clean install of Ubuntu 20.04 which does handle the clickpad properly so it is probably a red herring.
