My touchpad is 'working' but KDE settings says it is 'not found'

General system Kernel, boot, graphics & hardware

I have a Lenovo Thinkpad X1 Nano running Plasma 6.0.3 and kernel 6.8.2

The trackpad has been working and ‘found’ up until last week. I noticed the scroll direction was back to the default when swiping up or down, so I want to go back into the setting and invert it again.

However, when I go to the Trackpad settings in KDE, I get the message “Trackpad not found”

Any ideas on how to “find” it (or at least get my scrolling fixed again)?

Thank you!

Are you on X11 or Wayland?

Can you post the output of

It appears that your trackpad is indeed detected. This smells like a bug in KDE’s GUI. For now, try to configure the trackpad using an xorg configuration file first.

Create a file called /etc/X11/xorg.conf.d/trackpad.conf with the following contents:

Section "InputClass"
    Identifier "Touchpad Custom Configurations"
    MatchIsTouchpad "on"
    Option "NaturalScrolling" "true"
EndSection

Reboot and test.

P/S: I’m not sure if reverse scrolling is what you want (it was unclear from the original post); if it isn’t, just set NaturalScrolling to false instead of true.

Thank you. For some reason I was getting a loop trying to log back in to the X11 session, so I logged in using Wayland and the touchpad is detected there with the KDE settings!

Probably due to the Xorg config file you just added. If you still want to test, you can try to modify the file contents to:

Section "InputClass"
    Identifier "Trackpoint Custom Configurations"
    MatchProduct "ELAN0670:00 04F3:3150"
    Driver "libinput"
    Option "NaturalScrolling" "true"
EndSection

Thank you! I’ll make the edit and give that a try

Works great. Thank you!
