This is kinda unrelated to the post but do icc profiles now generally work on wayland? I thought last time i read about it it didn't work yet but maybe i'm mistaken.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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!
Damn, so that was the issue. I spent 2h trying around with different packages I suspected to cause an error during start. Then I desperately moved my .config dir out of the way to rule out an incompatible config and lo and behold... it worked. I then moved it back and tried to delete configs more finegranular. After a few iterations without success I just removed almost all kde and plasma related configs and reconfigured everything from scratch. I should have scrolled through my feed earlier 😁
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.
This is the sort of shit that btrfs snapshots (snapper) was made for. Boot after update, something is borked, no obvious problem or solution, fuck this take me back
I had something similar happen in Plasma 6.1 and 6.2. After I turned off the dccutils support in powerdevil, I have not had the issue since. My desktop is not a laptop, so it's always powered, same with screen, so I don't need fancy power profiles.
