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When using Xorg and a newer version of the driver 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
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!
