With 18.04 the situation got worse. Apparently, the login screen tries to run now on Wayland as well, so the opportunity to turn it off is gone. Booting simply stops at the Ubuntu logo, with the first of these five dots filled.
Booting in recovery mode, then choosing 'continue'(?) gives a black screen most of the time, with some text blinking up shortly from time to time. Managed to catch it, see attached picture. The only way I could get this PC up running after the 18.04 upgrade was to boot into recovery mode, then get a root shell, then edit /etc/gdm3/custom.conf to remove the comment sign in front of WaylandEnable..., then reboot. ** Attachment added: "Screen photograph" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1727356/+attachment/5134590/+files/DSCF1218.JPG -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1727356 Title: Wayland does not start up on "Integrated Graphics Chipset: Intel(R) G33": Shader compilation failed Status in GNOME Shell: Confirmed Status in gnome-shell package in Ubuntu: Triaged Bug description: $ lsb_release -rd Description: Ubuntu 17.10 Release: 17.10 Upgraded from 17.04 today.
