Update: Bug fixed in Plasma 6.3.1
Just posting this since I spent over an hour trying to figure out why I couldn’t open my desktop today… After booting and logging in I got a black screen. Switched to a terminal but did not see any obvious errors in the logs.
Not fixed for Fedora 41 KDE yet, so I installed plasma-workspace-x11 to use in the meanwhile. Anyone who hasn’t updated to 6.3 yet could probably change their display settings to not use ICC profiles to avoid it.___
KDE has had ICC support implemented for a while now in Wayland. The necessary protocol for ICC support/color management in Wayland recently got merged, so the next release of many popular compositors (plasma 6.3 for KDE) will be protocol-compliant.
That’s great, thanks for the info!
