OK i will report it to nvidia. But with the nouveau drivers it's also not
working. Are you sure it's not a kernel problem?
Because according to systemd it would be a kernel problem. (personaly i am
also thinking it's a driver problem)
Unfortunately, it's not easy for Nouveau to debug problems with GSP-RM.
However, if the problem exists in the proprietary driver, then Nvidia could
fix it. That would then lead to a new version of OpenRM that Nouveau could
use.
I have contacted Nvidia and now i can see the outputs such like this:
─/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/card0
│ [MASTER] drm:card0

But the problem is now the same of with the Nouveau driver. When you do
this:
loginctl attach seat1
/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/card0/card0-VGA-1
For the seat1 (the VGA d-sub output for seat1 and the other HDMI output
for seat0) and of course the mouse and keyboard.
When you do this, all the graphics outputs are on the second seat
(seat1) and not anymore on the first seat. So i need to move only the
VGA output to seat1 and not all the outputs.
The problem is that linux can not start 2 or more window managers on one
card (even if you don't need a multiseat, but use only one mouse and
keyboard).
So how can i fix that i can use more than one window manager on one
physical graphics card? (without Xephyr or something because they are to
outdated and works not good).
I have tried with: Linux Mint, Ubuntu and Debian all the same problem.
