OK, something's wrong with my computer. I'm at a TTY (not PTS!) right now (i.e. Linux "fullscreen" console). Weird graphical things. My Sway Wayland compositor crashed, Zen browser is freezing and displayed garbled visuals, part of my mouse cursor turned pink for some reason, and this TTY keeps on getting weird small white lines on it (like 3x already).
Probably #Nvidia / #Nouveau , as usual (Nvidia sucks >:( ). Gonna try some different Nvidia drivers, I guess. I'm a diehard #Wayland fan, though, so I'm sticking with Nouveau even if it means my session occasionally degrades and falls apart (and the inconsistent framerate... oof!) [if Nouveau is the only one that works, I mean.].
Usually when I use an official Nvidia driver, lots of stuff turns black and won't come back when I resume from suspend.
OK, so I tried a few other Nvidia drivers. Not working. Actually briefly considered switching to a much cheaper laptop I have on hand, just to get away from Nvidia. But it's Lenovo (I try to avoid Chinese tech, for obvious reasons); might be worth it though.
I had just assumed that by buying a #System76 I could avoid compatibility issues, but... here we are. (To System76's credit, though, they're very up-front about their laptops using Nvidia GPUs.)
