I didn't know how to log into "Ubuntu" instead of "Ubuntu on Wayland" since I only got a blinking cursor and no logon prompt. I edited /etc/gdm3/custom.conf and rebooted.
Successfully got a GUI logon prompt and was able to log in to the desktop. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1826025 Title: gnome-shell trap int3 no desktop ("Impossible to lock surface front buffer: Function not implemented" on Matrox graphics card) To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1826025/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
