Linux thinks ctrl is held down

Issues & Assistance KDE
1

For the past few weeks i have had the intermittent problem of the PC thinking the ctrl key is being held down despite there being no input devices plugged in, I have tried using SSH to shutdown KDE connect and unplugging all my devices but has not helped.
I have looked into a few different ways of figuring it out such as apps like “showmethekey” but they don’t show where the input is coming from, I have also tried following this but i don’t know how to read the output or if it would even help.

You don’t happen to remember if an update or the installation of an app/game caused this?

6

No i think it has been a problem since i first switched to Wayland

7

Try installing an OSK utility to see if it can be changed using a virtual keyboard. Just FYI onboard does not work on wayland.

I had a thing the past month where my kernel thaught i had closed the Lid and send it to sleep but lid was open. I played around with amd-ucode package from git and all is good now. Might be something to look into, some microcode packages have been a little buggy

where did you face this issue? Are you getting the same behaviour in a TTY? How did you check this with no input devices connected? Does this apply to all applications or just to some? Could you try unplugging your usb wireless thingy just in case? Does your mouse have special mappings - maybe second layers or something?

xmodmap does work on wayland as far as I know.
