This can be fixed by putting the full path to unity-greeter in the desktop file, which is owned by the unity-greeter package. Moving over there. I'll work on it if time permits.

After the "ubuntu loading screen" with the dots, the display reverted to a text screen, ending in some information about "battery status". After logging in on tty1, I could start gdm as a workaround. The problem is twofold. First, /var/log/lightdm/x-0.log (and I think /var/log/lighdm/lightdm.log as well) complained about insufficient privileges to create /var/log/lightdm/x-0-greeter.log. After `chown lightdm /var/log/lightdm" said file was created (when restarting lightdm) containing the single line exec: 33: unity-greeter: not found If this happened to a new user, they would be lost!
