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.
It was surprisingly difficult to find, the majority of comments about 6.3 were people saying it was working great, but I guess most people don’t use ICC profiles for their monitors.
