I just upgraded to Ubuntu 23.04 from 22.10, upgrade indicated no errors. I rebooted onto Ubuntu 23.03, the reboot produced a blank screen. I powered off and waited. Powered back on, the Ubuntu logo appeared when through all the usual processes but still no login screen just blank. Any assistance would be appreciated. Do I need to do a complete install? The host machine is a Dell XPS15.

I've had this problem after a 23.04 upgrade. The only way to get the display to work was to boot with the nomodeset option, but then my external monitor wasn't detected. I've solved enabling Wayland, that for some reason was disabled.

You can check if Wayland is disabled in favor of Xorg with

echo $XDG_SESSION_TYPE

If the output is x11, you can enable Wayland editing the file /etc/gdm3/custom.conf and comment the line

#WaylandEnable=false

or modify it to

WaylandEnable=true

then reboot pressing Ctrl+Alt+Del and be sure to select Ubuntu clicking on the gear icon at the login screen.
