Yes the problem repeats after reboot after couple days running without reboot - not sure about the root cause.
E.g. not right after the reboot but couple days after. My best guess is that its somehow connected with sleep mode.
I installed evtest
, but it does show nothing when I press Fn button (both when Fn
is not working, and when Fn is working after reboot) So it might not be the best tool for testing Fn
stopping registering in the system.
F1+Fn and F1 has not difference when this issue happens. Below, copied output from evtest
just turn on-turn off for F1+Fn as for F1 only its identical:

after reboot, Fn+F1 and F1 only - working correctly now:
