Bug Description

I'm testing the desktop-amd64 daily iso from 2012-08-22.

Image: http://cdimage.ubuntu.com/daily-live/20120822/quantal-desktop-amd64.iso

I've attempted to boot this on 3 machines with both Intel and AMD graphics. On all machines I get to the Ubuntu splash screen with the colored dots followed by a blank screen. The welcome screen does not display. If I interrupt boot using F6 and select the "Try Ubuntu ..." option I can get to the live desktop just fine.

From some light debugging I did it looks like when lightdm tries to start X, X exits with the following:

[ 16.385] (EE) Screen(s) found, but none have a usable configuration.
[ 16.385]
Fatal server error:
[ 16.385] no screens found

There seems to be another X process already running, so perhaps this is related.

I'm attaching a full set of logs (from /var/log) for a failed boot.
