Title:
[nvidia] HomeOffice & Un-/Docking: X11 crash on resume when docked to
multi monitor
Status in X.Org X server:
Unknown
Status in nvidia-graphics-drivers-460 package in Ubuntu:

Bug description:
X11 crashes on resume and my current desktop is lost and the login
manager appears.
I posted a bugreported here
https://gitlab.freedesktop.org/xorg/xserver/-/issues/1197
with configu details.
But it seems to be nvidia, but may be a workaround is possible in Ubuntu?
This bug prevents me to use Linux for daily docking /undocking cycles for
HomeOffice (works fine with Windows).

I found something similar which could handle the EnterVT failed issue:

but I am not sure if it is already in Ubuntu 20.04 LTS
