--- Comment #55 from l...@protonmail.ch ---
I have a very similar problem, although the few differences is that my entire
screen becomes one single color, which doesn't seem to be entirely random. Some
times it is grey, other times a blueish tint, but never colors like black.
In addition, num lock etc. are still responsive for a small while, although it
seems that a delay in the response time is added rapidly each second, very soon
seeming completely unresponsive.
My system:
CPU: AMD Ryzen 5 1600
GPU: Sapphire NITRO+ RX 580 4 GB
Motherboard: ASUS ROG STRIX X470-F
Kernel: 4.20.1
Distribution: NixOS
WM: Sway or i3, happens in both
I am using DVI-D, if that is at all relevant.
Oddly enough, even though the symptoms have stayed the exact same the entire
time, the error messages I get very widely. At one point I was getting the "GPU
fault detected" errors, at other times it would say that an sdma0 ring or gfx
ring timed out, and now I have no errors at all when it happens, which seems to
have happened after I switched from an HDMI display to a DVI-D display (it also
seems to have become much more infrequent oddly enough?).
Another interesting thing is that when I was using 4.18.12 or lower, I could
avoid this problem entirely by flipping my VBIOS switch away from the IO ports.
In addition, when it starts happening, if I reboot my system by just turning it
off by holding down the power button and then turning it on normally, it will
happen soon again after launching my WM. This is seemingly avoidable by
completely disconnecting it from power, e.g. by turning my PSU off.
This might actually be a completely unrelated bug, but the symptoms seem to fit
enough, that it could be the same bug.
It could perhaps also be a hardware bug, since it is very odd that the errors I
get change, or maybe it is multiple bugs that seem to be the same? In addition,
I can't find a definite way to reproduce my issue instantly other than just
waiting for it to happen, although of course graphics intensive work does
accelerate it considerably.
