[solved] Elan touchpad recognised but not working

f-elixxx · 2021-08-02 18:42:21

Hey I just installed Arch 5.13.7 on a Lenovo ideapad 120S-14IAP with kde Plasma 5.22.4 and it seems to not recognize any touch pad input (tapping, moving, clicking).
The touch pad works just fine with ubuntu and kubuntu respectively.

EDIT: It also doesn't work with the 5.10.55-1-lts kernel.

Here are some (hopefully) helpful outputs:

$ xinput list
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Elan Touchpad                           	id=10	[slave  pointer  (2)]
[...]

EDIT2:
in the journalctl I get the following message:

elan_i2c i2c-ELAN060F:00: invalid report id data (1)

Any help would be greatly appreciated.

I fixed it by blacklisting the elan_i2c module -
i.e. i added

blacklist elan_i2c

to the /etc/modprobe.d/blacklist.conf file.
