Public bug reported: Hi there -- I figured I'd try 15.10 a few days before release, and when gdm is the default greeter, I see no login prompt and I have to CTRL- ALT-F1 to get to a terminal. As far as I can tell, there's nothing interesting in the logs in /var/log or /var/log/gdm. I just get a blank, black screen.
As a side note, I'm seeing the error messages described in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1492764, but I don't think they are the root cause for a missing X-server (AFAICT, there's no X server starting). Please advice on how I can troubleshoot further. `dkg-reconfigure gdm` and choosing lightdm yields a GUI login prompt in lightdm.
