[Solved] Thinkpad L580: Touchpad not recognized

Hi,

today I installed arch on my laptop with i3 as window manager. After a few hours everything worked fine except the touchpad. I can't get it to work even after a few hours of troubleshooting.

According to the documentation it should work out of the box with libinput and the old synaptics shoudl be avoided. Nevertheless I tried it and they aren't working either.

It seems that the touchpad isn't recognized because with 'xinput list' or 'libinput list-devices' I don't get anything with touchpad in the name (only ThinkPad extra buttons, but I assume these are the function keys).

On .local/share/xorg/Xorg.0.log I have two errors
* open /dev/fb0: Permission denied
* Failed to load module "intel"

I would be really glad if someone has an idea for me? By now I am clueless what I should try next.

Ok, found finally a solution and hopefully this will also help others.

I am not sure what this does, but it works
sudo sh -c 'echo -n "elantech" > /sys/bus/serio/devices/serio1/protocol'
