[SOLVED] Touchpad not working

Device: Thinkpad X1 carbon gen12

After install arch the touchpad was not working. After I have installed fwupd it worked. I installed other packages too. After a reboot the touchpad is not working anymore. The touchscreen, mouse-keys on the touchpad and the nipple are working fine.

the installed firmewares are (if helpfull):

thinkpad% yay -Ss firmware | grep Installed
aur/ast-firmware 501-1 (+26 1.19) (Installed)
aur/upd72020x-fw 1:1.0.0-2 (+120 6.53) (Installed)
aur/wd719x-firmware 1-7 (+293 2.84) (Installed)
aur/aic94xx-firmware 30-10 (+353 1.87) (Installed)
extra/sof-firmware 2024.03-1 (1.3 MiB 26.6 MiB) (Installed)
extra/fwupd 1.9.18-1 (5.3 MiB 11.6 MiB) (Installed)
core/linux-firmware-whence 20240409.1addd7dc-1 (35.5 KiB 307.9 KiB) (Installed)
core/linux-firmware-qlogic 20240409.1addd7dc-1 (11.4 MiB 11.5 MiB) (Installed)
core/linux-firmware 20240409.1addd7dc-1 (222.9 MiB 228.2 MiB) (Installed)

I also installed fprintd and intel-media-driver.

I'm using KDE plasma 6 with wayland.

I'm not sure if I had done something wrong or the device is too new. On the arch-wiki, for the x1 carbon gen12 is written, that the touchpad should work.

Re: [SOLVED] Touchpad not working

Double check in e.g. your environment/DE settings that it's not disabled due to presence of another "mouse" (the "nipple" often qualifies here and makes it logically disabled).

Re: [SOLVED] Touchpad not working

Plus you can also execute (might require to install):

libinput list-devices

To discover the touchpad devices and:

libinput debug-events /dev/input/eventNN

to see if your touchpad is generating and event

libinput debug-events /dev/input/eventNN

I cannot find my touchpad. /dev/input/event8 is the touchscreen

Double check in e.g. your environment/DE settings that it's not disabled due to presence of another "mouse" (the "nipple" often qualifies here and makes it logically disabled).

I disabled the "nipple", but the touchpad is not recognized at all. The "nipple" is recognized as a mouse.

Re: [SOLVED] Touchpad not working

OK so if it worked before see your last installed packages (using /var/log/pacman.log) and try to track down what had changed.
* Check that you can't see the device in: /proc/bus/input/devices as well.
* Check whether anything in dmesg.
* Check and perhaps reset BIOS configuration.
* Check different kernels (e.g. with the lts).

If you suspect the firmware caused it you can downgrade.

Ok, I don't know what exactly the problem was. I tried to uninstall the latest packages. Because I set the laptop up freshly, I reinstalled arch
The touchpad is working after install the necessary firmwares and xf86-input-synaptics. I am pretty sure I had installed the package at the first try too.

Now the trackpoint, touchpad and touchscreen are working simultaneously.

Let's hope, that the problem won't occur again.

Thanks for the help

Edit:

I haven't installed anything new. Just rebooted and now the toudpad is not working anymore...

Re: [SOLVED] Touchpad not working

xf86-input-synaptics is superseded by libinput.
Check this section and my bullet points above.

Changing the kernel to LTS did the trick.
Thank you!

Re: [SOLVED] Touchpad not working

That's great.
You can also experiment with other kernels to see roughly which version causes this.
