I might have some news for this bug: First is, if i remove "quiet splash" from boot, the bug disappears as well.
More importantly though, if I have the blank login screen, and I connect an external monitor, the screen shows up. If I go to a tty (Alt-Ctrl-F1) and back to X (Alt-Ctrl-F7), the screen is blank again. Then, if I pull out the external monitor, the login screen shows up again. Summed up 1. toggling external screen connection brings login screen up 2. switching to text and back to X kills it It takes 1 to 2 seconds to bring the screen up after the cable is connected/disconnected. I am on toshiba portege Z930-14L 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) By the way, I noticed (very rarely) that when logged in, the "screen refresh" may "lag", that is when for example typing a command in the shell the last character of the command would show up only after pressing enter. I believe this was not particular to the shell, but since it happend only once or twice on this new laptop I cannot tell for sure. Can I do anything to further debug this?

Status in Upstart: Confirmed Status in “lightdm” package in Ubuntu: Triaged Bug description: Sometimes lightdm comes up fine. Other times it appears to fail. x-0.log shows it tried to load 'nv' (rather than 'nvidia' which is what actually exists). When I then log into console and 'start lightdm', it comes up fine (on :1). I've not had it come up ok today, so I don't know if, when it comes up fine, it starts on :0. No idea if the lightdm.conf needs a change to 'start on'clause, or if this is just a case of a bad shipped config file (for module 'nv').
