I had the same problem... but not able to recover following your instruction of reinstalling gdm and gdm3. I had to switch to lightdm and now running lightdm. Not able to switch back to gdm. I'm using a ATI Radeon Graphic Card.... not sure if that has any thing to do with the issue.

lotuspsychje, has the problem reoccurred? Or ever occurred more than once?

If it does then please try moving/removing /var/lib/gdm3/* and reboot (per bug 1779476).
