Public bug reported:
In 24.04, attempting to launch into a Remote Login RDP session (which
uses the wayland compositor) with an Nvidia GPU connected on the host
gives a black screen. The purpose of having the GPU is to provide HW
acceleration to gnome-remote-desktop on the host (the RDP host is a
24.04 VM.) The Nvidia GPU does not have a display adapter, therefore a
dummy adapter cannot be used to fool the machine into believing there is
a monitor attached. The Remote Login session is only black screen if the
Nvidia GPU is attached. When the RDP client (I am using the standard
Remote Desktop connection client on a Windows 10 device) logs out from
gnome-remote-desktop, both grd and gnome-shell crash with SIGSEGV.
In Ubuntu version 22.04, attaching a Nvidia GPU to the 22.04 host VM and
launching a gnome-remote-desktop on "Ubuntu on Wayland" did not cause a
crash or any black screens, and the RDP instance had fully supported HW
acceleration for the desktop.
