The workaround works perfectly, thanks. I forgot to mention in the bug report that I had tried previous kernel versions, which didn't work for me either.

Lightdm can be started manually from tty1, for example, after the machine has been booted up. If the default browser is set to gdm, then gdm starts up on boot. This problem first arose immediately after upgrade to 3.2.0-45-generic (from 3.2.0-44) in Ubuntu 12.04.2 LTS I have tried, to no avail, 1. Moving etc/X11/xorg.conf to a backup 2. uninstalling unity-greeter, lightdm, lightdm-gobject-1-0 3. deleting /etc/lightdm and /var/lib/lightdm 4. rebooting and reinstalling unity-greeter, lightdm, lightdm-gobject-1-0 5. Adding the line "sleep 2" immediately before "exec lightdm" in /etc/init/lightdm.conf 6. Checking that /etc/X11/default-display-manager says "/usr/sbin/lightdm" After reinstalling all the above it was necessary to change ownership of .Xauthority from root to my userid, to allow lightdm to accept a password. After this lightdm still works but still does not start up on boot.
