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.
