Hi,
I have a laptop using and AMD CPU+GPU and a discrete NVIDIA GPU.
In very short, I have this setup:
Monitor 2 ← DP cable → Monitor 1 ← USB C → Laptop
When using Xorg and a newer version of the driver > 525.60.11, Monitor 1 does not work.
The behavior is very strange. If I disable monitor 2, monitor 1 works.
Re-enabling monitor 2 makes monitor 1 show a partial frame.
Then, the two of them stop working at random while making the other work. Sometimes.
I really cannot figure out what is the issue at all.
Running Wayland has no issue, the monitors work perfectly.
It is just that Plasma is not very Wayland-friendly and a bit unstable.
I am attaching the log generated from the “nvidia-log-report” script.
Other information that can be useful
OS: ArchLinux, all packages up to date
Desktop Environment: Plasma 5.27, happens also in GNOME
Kernels: Both 6.1.19 LTS and stable 6.2.6
Current workaround
Downgrade the driver to 525.60.11.
The driver however does not work with the stable kernel, only the LTS one.
Let me know if I can provide more information!
