Further info: I updated my main computer to 18.04. That one has Nvidia graphics (updated to the latest nvidia-390 from PPA). Behaviour is different, but buggy, too, as follows:
1. boot
2. Hit ctrl+alt+f3. Console shows. Log in. exit (log out).
Expected behaviour: return to gdm's graphical login screen with responsive keyboard and mouse.
Actual behaviour: the gdm's screen appears but keyboard and mouse are unresponsive...
3. Hit ctrl+alt+f1.
Expected behaviour: even if ttt3's screen seems corrupted, hopefully ctrl+alt+f1 would return to gdm's graphical login screen with responsive keyboard and mouse on tty1.
Actual behaviour: screen blanks. Computer is unrecoverable from keyboard and mouse. Only REISUB can reboot it again (alternatively, accessing it via SSH shows that the OS is still alive and well, but graphics are messed up).
In summary, both Intel and Nvidia behaviours, in two different computers, seem buggy, although the actual behaviour is slightly different for each case.
A bold conjecture: does GDM use Wayland or X? Is this caused by any Wayland/X switching?
