Tried it again a few months ago when HDR support first dropped in KDE. It didn’t work at all. Everything was desaturated and dim. Literally the opposite of what HDR is supposed to do.
I’m giving it another year before I try Linux again. Hopefully the bugs are sorted by then.
As others have suggested, I’ll probably just throw LTSC on it and call it a day. That’s what I did for my DJ laptop (the mixing hardware isn’t compatible with Linux), and it works phenomenally. It’s the perfect Windows OS for a single-use PC.
