external Monitor causes shell to freeze

Kabelsalat · February 17, 2025, 10:28am

After me enabling HDR + “prefer color accuracy” on my external monitor my system (Laptop) started to freeze. Disconnecting the monitor makes my system responsible again. It seems like i cant undo that setting by deleting ~/.local/share/kscreen/ and rebooting, at least i’ve tried that to no avail.

I want to add that only enabling hdr didn’t cause this issue, it was only after enabling HDR AND “prefer color accuarcy”.

Any suggestions on how to fix this?

I’m on Fedora 40, Plasma 6.3.

Thanks in advance.

Plasma 6.3.1 will bring a bunch of fixes, released tomorrow Tuesday 18th, it would be interesting to report whether your issue has been fixed with this version or not.

Kabelsalat · February 17, 2025, 10:37am

Okay, i’ll report back after having installed the update.

After having updated to Fedora 41, Plasma 6.3.1, the problem still persists.

Ive additionally observed that the system freezes when connecting the monitor directly via usb-c, but actually crashes when connecting via docking station.

I’ve added the crash-report that kwin gave me after the crash.
