Couldn't log in because the gdm3
login screen has no password field, see screenshot:
The unability to switch from current session to the TTY3 text console (Ctrl+Alt+F4 or F3 didn't work here) forced me to restart in recovery mode in order to select lightdm
instead of gdm3
using:
sudo dpkg-reconfigure lightdm
which did work fine.
I retried:
sudo dpkg-reconfigure gdm3
after having uninstalled gdm3
with:
sudo apt purge gdm3
and reinstalled with:
sudo apt install --reinstall -y gdm3
with no success. The same blank login screen is still there.
Any clue would be greatly appreciated.
P.S.: Error message on upgrade day (never seen before):
