I am having an issue where my screen(s) will go black, then a moment later come back. It only happens under very low load. I can keep typing, usually, to the point I can press F12 and type reboot and it will reboot, but the screen is frozen.
So, if I keep a game running 24/7 it never crashes, but if I am just typing in Discord or AFK the computer can just go toes up at any point (there is no seeming pattern to the issue).
What’s my best bet for catching this in the act? Xorg logs roll over when I reboot, so what should I be looking for before I do reboot? I can usually Ctrl+Alt+F2 to get to a terminal. What commands should I be ready to run to catch this issue? Obviously I should look at the Xorg.0.log in /var/log, but what else? Can I increase the level of what’s being logged? Is there a way to trace the driver in case it’s crashing?
I do see an
drmmode_do_crtc_dpms cannot get last vblank counter event message that seems to correlate with the screen going black. I use VRR so VSYNC is totally irrelevant to me, can you turn it off altogether in Xorg?
