In my case the screen stayed black with a few color spots and it happens only with X.org
By clicking directly on "install ubuntu", I could install and it booted fine. I noticed performance issues and tried X.org session and got the display bug again. While I had selected "Auto logon", I had to use recovery mode to get back on wayland with :
sudo nano /etc/gdm3/custom.conf
and edit WaylandEnable=
There is also a line for auto logon by the way.
Unfortunately, with wayland I'm experiencing frequent freezes and I am falling back to Focal on this machine.
Edit : This is an intel machine (Celeron N3150)
