Hi, I’m experiencing issues with KDE Plasma’s login screen. Whenever I have my system sleep for a couple of minutes and I wake it up. It just gives me a black screen. Only my cursor moves and nothing else. I have to open the TTY terminal and restart sddm to have the login screen show and it’s been a nuisance. I’m using proprietary NVIDIA drivers.
A bit more system information would be useful.
Are you using X11 or wayland?
Which Plasma version?
Which distro?
etc..
Could be:
Hi, sorry for not providing more useful information. I’m using X11. My plasma version is 6.3.5 and I’m using Arch Linux.
I wouldn’t be surprised if it was related somehow to bug 484323 .. To resolve the issue there, I do a killall kwin_x11 when I start a session and thereafter the problem doesn’t manifest (the thread describes how to set up a mitigating systemd service which is probably the way to go). But, as far as I know this bug hasn’t been resolved and I have a feeling it will linger because of wayland.
I do regular updates, etc. (i.e. Arch with kde).

Yep, turns out this was the issue. I locked my computer and used htop to check the CPU usage in htop using TTY and it turns out that the login screen utilizes 100% of the CPU and crashes.
