Have to manually 'startx' after upgrading to 18.04

I upgraded from 17.10 to 18.04 today. I didn't see any errors during the upgrade, but now when I boot I only get a graphical console. However, startx brings up the Gnome desktop just fine, so I don't think that there are any fundamental problems.

Grep'ing shows that there are no EE entries in /var/log/Xorg.0.log

Where should I be looking to restore the normal graphical boot?


Solution 1:

Re-initialising gdm3 has helped:

sudo dpkg-reconfigure gdm3

Although it took two reboots for my system to be completely happy again.
