** Description changed: On Ubuntu 20.04, I have an AMD system with an integrated GPU (Ryzen 3 3200G with Radeon Vega 8) - I am using lighdm instead of gdm3. My GPU is using the amdgpu driver. I have no specific xorg.conf in place. I am using x11vnc to login and view the desktop remotely. There is no monitor attached. + I am using lightdm instead of gdm3. My GPU is using the amdgpu driver. I have no specific xorg.conf in place. I am using x11vnc to login and view the desktop remotely. There is no monitor attached. After logging into lightdm's greeter, I am presented with a blank desktop with the Focal Fossa background image and a mouse cursor, but no other visible interface or windows. There is no menu bar at the top of the desktop and no application bar on the left. This all works perfectly fine if a monitor is attached before lightdm (and thus Xorg) is started. If I change the settings at login to use fvwm for my session it works fine. This is also the case for Gnome Flashback mode (using metacity). But the default of gnome-shell/mutter does not work without the monitor. Nor does using Wayland.
