apport information ** Description changed:
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.
