Huh, waking issues have been plaguing me for ~9 months in regular Fedora KDE, to the point where I don't let my PC sleep and just shut it down at night. Hopefully this fixes it there too.

Are you kidding me, that worked?!

I mean, there's no color profile option in the current KDE Plasma display config for HDR on Wayland, but just for the crap of it I flipped their "efficient color precision" to the "accurate" setting, which gives you a performance warning and it went to deep sleep for several hours and recoverd once successfully.

I hate it here. I'm going to choose to believe this was a fluke and when I leave this thing on overnight it'll die in its sleep as it's been doing for a while.

That's a weird bug but I'm going to give it a shot!

That's... random.

But hey, I've tried a bunch of the logical, actually-sound setup tweaks unsuccessfully, who knows what dark rituals the proprietary Nvidia drivers demand to come back from the dead at this point. I'll give it a shot next time.
