Each time I try AMD graphics, something is fucked for me. Back with fglrx, fglrx just sucked, so I used Nvidia. Then I had an AMD right around when they finally had opensource drivers, but it was still buggy as hell. So I went with Nvidia again (first a GTX 790, then a GTX 1060). In the meantime I had a new work notebook where I also went with an AMD APU, and had driver crashes for a long time when I was in video calls and it had to decode multiple streams. That thankfully stabilized with Linux 6.4.
Since sooo many people in the community swear by AMD, I thought “dammit, let’s try it again for my new desktop” and got an 7800rx … and I have to reboot ~5 times until I finally make it to a running xserver or wayland session. Apparently I am hit by this problem (at least I hope so). But that doesn’t even read nice … the fix seems to be to revert another fix for powermanagement. So I either have a mostly non-booting card or suboptimal power management.
I start to regret having chosen AMD … again :-/ I seem to be cursed.
That doesn’t rule out the possibility of display issues tho, back when I had the faulty monitor it was much more severe under Linux, I never managed to track it down tho (using AMD hardware for over 10 years now, this one issue busted my nuts pretty hard)
If you have a TV or something, at least try it to rule out possible outside factors
It can’t hurt. I’ll grab another display and another cable and try a few combinations. Thanks!
