Additional Monitor Regularly Disconnects with GeForce 3090 on Arch Linux

Graphics / Linux Linux

Around 60-70% of the time that I boot into my Arch Linux Operating System, one display port will continually disconnect/reconnect, but never long enough for it to become available to the X Server. I tried running a pass through the logs to see if I can spot an inconsistencies, but I couldn’t find much. I have a bug report from both when it fails to connect (the former) and when it succeeds (the latter).

Bug Report when the Additional Monitor is functioning: nvidia-bug-report.log.gz (277.7 KB)

The primary giveaway so far has been this from the Xorg logs…

Any insights into how to debug this further would be greatly appreciated!

Did you ever manage to find a solution to this? I’m seeing similar output on Arch Linux with a GTX 1060.

I did not, I ended up just leaving the desktop on at all times and preventing the suspend/hibernate state. My system is waiting for some parts for an upgrade, I will try to debug it after those parts arrive.

Do you have the debug reports? Maybe we could correlate with the logs I have attached to see any similarities.
