Issue with Guest and 2 Displays
Hi @ all
Since switching from Debian 10 to Debian 11, I've had a new small unsolved
problem... with essentially the same customizing as before.
It all takes place on my local Desktop-PC, where I have set up a
restricted VM for actions in the internet.
After I started the VM locally on my PC, I can operate the VM with the
virtviewer without any errors. If I then open the second monitor via
the Menu 'View->Display', a blank white window appears with the message
"Waiting for display 2".
xrandr correctly shows the second display as disconnected and also all
available display-modes.
After the following command
xrandr --output Virtual-2 --auto --right-of Virtual-1
both (!) displays are white and both are waiting for a display.... and
nothing works anymore.
A previously started SSH connection to the VM from the PC shows the
following for this moment:

$ ssh 192.168.100.10

It is no longer possible to restart the VM via "systemctl reboot",
the VM is probably stuck in some systemd-timeouts, only
"systemctl reboot -ff" leads to a reboot as a hard intervention.
Does anyone know this problem? Is there a solution for this, to get the second display
working?
Below some relevant system-informations of my PC and the VM.
