So a few weeks ago I installed updates like normal, rebooted my system, and after logging back in noticed my primary monitor keeps blanking repeatedly. The screen goes black for about a second and a half, then it comes back and it displays the “Display Port” message like it had just switched inputs or turned back on. After a few seconds it repeats. After messing around with a few things I just rolled the update back and it was back to working normally. I waited a few days hoping maybe there was a bad package or something and retried the update to the same result. At various times over the last couple weeks I’ve repeated this, as well as checked the output of various logs to see if there was some kind of obvious error message I could look for fixes for, but there’s absolutely no errors I can find I the logs that seem relevant.
I initially suspected this was an issue with Hyprland or one of its dependencies, so I swapped over to Plasma and that did initially seem to fix the issue, but when I enabled variable refresh rate in the plasma settings it started exhibiting the same behavior. I thought that if I just keep that disabled it would fix the problem, but once I started attempting to game it started happening semi-randomly, usually when cutscenes played, although I could also trigger it by simply focusing a window in my second monitor (which has been working perfectly this entire time). So this might be something related to either changes to refresh rate, or possibly mode line. It seems to happen fairly infrequently in Plasma (but it still happens), where as Hyprland it triggers very very often. By disabling VRR in my Hyprland config I can reduce it, but it still occurs far more often than it does in Plasma.
I’m honestly a little stumped on what to do next as I’m not even sure of what component is to blame. It could by the GPU driver, it could be the compositor, it could even be the monitor hardware itself I suppose, although the fact the issue goes away if I rollback to an earlier state seems to suggest it’s software and not hardware.
At this point, if someone doesn’t have an idea what the issue is I’d like to hear suggestions of logs to check to help debug. I checked dmesg and nothing jumps out there, and I checked Hyprlands logs and likewise nothing looks out of the ordinary there. I’m considering once again rolling back to my last known good state, but since it’s been weeks since then I’m not thrilled with that idea. I’d prefer staying up to date with my software if I can, but with my primary monitor being nearly useless because of this bug I’m not sure if I can actually do that.
