with these KDE repositries

sometimes after resume from sleep on RAM keyboard become urresponsive, I have to reboot (logout doesn’t works) and I use virtual keyboard and mouse, that works, to login and to close programs and reboot and keyboard works again, as I can use virtual keyboard how can I investigate or have keyboard working again without rebooting?

#2

Have you tried if a restart of plasmashell gives you a working keyboard again?

#3

No ideas, how to investigate; just a “me too”. I have the same problem on a Tumbleweed system with an AMD cpu with integrated processor graphics (Ryzen 5600G) and AMDGPU driver.
Killing the session with loginctl sometimes works, but reboot is the only safe way.

#4

I will try when it happens again,
the commands should be these, or you suggest others commands?

kquitapp5 plasmashell
kstart5 plasmashell
#5

if it is of interest my is:
CPU= Intel Core i7-8565U,
RAM=32Gb,
GPU=Intel UHD Graphics 620 (Whiskey Lake) Driver: “i915”;

#6

Find the session number:

loginctl list-sessions

kill it (here no. 3)

loginctl kill-session 3
#7

I have never used kquitapp5 (but it may work as well), I used

killall plasmashell; kstart5 plasmashell
#8

well, it happened, so I tried killall plasmashell; kstart5 plasmashell but the keyboard didn’t worked after and this is the result

then I tried kquitapp5 plasmashell & kstart5 plasmashell but the keyboard didn’t worked after and this is the result
then I tried Find the session number-loginctl list-sessions-kill it (here no. 3)-loginctl kill-session 3
also mine was n°3, but also the keyboard didn’t worked after , this way is worste of others becouse all the programs are quitted (and I would like that they remain opened becouse this is the aim of suspend and I like it) and is almost the same as reboot, but after rebooting the keyboard works.
I hope that this could be useful to solve this issue,
the command I would like to have should resuscitate the keyboard without quitting all the opened programs as in the first two attempts.
