## Problem
- Connect external display to DVI port on dock and run X with both
displays in use. 2. Wait hours or days. 3. Suddenly the secondary Nvidia-connected display turns off and X stops responding to keyboard/mouse input. In *some* cases it is possible to switch to a virtual TTY with Ctrl+Alt+Fn and log in there. In any case, shutdown/reboot after this happens is *usually* not successful (forced power-off is required).
This started happening after the upgrade to Debian bullseye, and the problem remains with Debian bookworm. [...]
Thanks for your report. With a bit of luck someone will look into this, But I doubt it, as this report has some aspects why it might be ignored. Mainly: (a) the report was about a stable/longterm kernel and (b)it's afaics unclear if the problem even happens with the latest mainline kernel. For details about these aspects, see: https://linux-regtracking.leemhuis.info/post/frequent-reasons-why-linux-kern...
You thus might want to check if the problem occurs with 6.6 -- and ideally also check if reverting the culprit there fixes things for you.
That might help getting things rolling, but it's a pretty old regression, which complicates things.
