I just installed Manjaro on my thinkpad E14 Gen 2, tried it with KDE and XFCE both works fine, only one issue I got. The FN-Keys are not working and the caps lock key also does not show the light when it was pressed. Laptop lid on close does also not work.
After the first time I suspend my laptop and I log in again everything works fine.
FN-Keys, the light on keyboard and lid on close.
I am currently using Kernel 5.9. On other Kernels I got the same issue, I didn’t tested if it works after suspend but it was not working out of the box.
