I have been 'enjoying' this with Debian on a PC with a 1080Ti nvidia card, which is no longer supported by the nvidia v590 + drivers. I've had to pin to v580, but the whole "oops, I updated, rebooted and 'look ma, no high-resolution anymore'" got tired really quickly. You have my sympathies.

EndeavourOS is apparently Arch-based so I've got no useful suggestions for fixing there, sorry.
