Hey Everyone, I’m running into an issue that’s driving me nuts, and hoping someone can help: I just downloaded the Plasma Desktop ISO and flashed it to a Live USB, then installed Manjaro on my SSD, and as soon as I log in for the first time, the kwin_wayland
process starts using 90+% of my CPU indefinitely, which makes everything else unbearably slow - just moving the mouse or hitting a single key takes 2-4 seconds to register on screen.
Things I’ve tried, and their results:
- Killing the
kwin_wayland
process - it just restarts and consumes most of the CPU resources again - Letting the system (slowly…) update everything so the whole system is up to date according to Pamac - no noticeable change even after a reboot
- Downgrading kwin to the version (5.27.4.1-1) that was running just fine on the Live USB I had just installed from - no noticeable change
- Installing free and nonfree graphics drivers (Nvidia card) - free was already installed, and nonfree didn’t have any noticeable affect
- Wiping the drive and re-installing everything again (more than once now) - same result
- Switching from the 6.1LTS to the 5.15LTS kernel - no noticeable affect
Is there anything else I can try to fix this?
