Sorry, no improvements.
I booted the live cd in single mode, modified /etc/gdm3/custom.conf as
follows, then exited the single mode and continued the normal boot
process.
1) First attempt:
#WaylandEnable=false
I can see the purple background for a moment, then I'm sent back to text
mode and the mouse arrow keeps flashing.
2) Second attempt:
#WaylandEnable=false
#AutomaticLoginEnable=true
#AutomaticLogin=ubuntu
This time I can't even see the purple background.
All boots were made without 'nomodeset'.
Thanks,
MZ

Title:
[radeon] GDM3 fails to load without nomodeset
Status in gdm3 package in Ubuntu:
Confirmed
Status in linux package in Ubuntu:
Confirmed
Bug description:
Both with the livecd (usb drive) and the installed version, I must boot with
the 'nomodeset' kernel parameter at GRUB; otherwise GDM3 will not boot (the
screen will keep on flashing in semi-textual mode, with a white mouse arrow
stuck).
This, however, prevents me from using the 'radeon' video driver, dropping me
to a very basic 1024x768 vesa mode.
The bug did NOT occur on Ubuntu 12.04, so it is a regression.
Also, the bug does NOT occur on XUbuntu/XFCE 18.04, so it is a GDM3-Gnome
related thing.
Thanks,
MZ
