Public bug reported:
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
