I can confirm that it seems to be ConsoleKit killing the session, because it's
taking out both DRI and audio.
This bug should probably renamed -- it's not merely an i915 issue.

I am seeing this about once a day. It happens after a compiz crash -
when it happens, unity tries to restart but the launcher and panel don't
appear.
Just now I tried the suggestion in comment #21 (ie from a root tty, kill
the X session and do killall -SIGABRT lightdm; start lightdm), but it
it works. It seems to have removed xserver-xorg-video-intel driver
before installing it through the software centre did fix it.

it is still not fixed for me after update to:
lightdm 1.0.1-0ubuntu6
Still there is no 3d acceleration and I can only use unity2d. Is there
any other step that needs to be done to fix this issue?

I captured a stack trace of the SIGABRT. You'll also find the trace from
a SIGUSR in there, but that looked like normal behavior.

I saw this for the first time last night. The symptons for me were the
user switching not being visible, and the dmesg log about LightDM
crashing with SIGABRT. Compiz kept running and was usable however. I'm
flying today so I wont be able to investigate it until I get there.

I think this is what just happened to me. Had a LightDM update earlier
and upon restart got the desktop with nautilus' menu across the top.

there are a lot of dbus reject messages and I also noticed this warning emitted
by several apps:

I'm lowering importance because 1) it is not easy to reproduce and seems
to requires very specific conditions to be triggered 2) restarting the

What I suspect is happening here is the lightdm daemon has crashed. When it
does that CK automatically deletes the ConsoleKit sessions it owned so even
though the session and X server continue to run you wont have permission to
access things anymore. You can confirm this by running:
$ sudo
I mean to say why hasn't *upstart* restarted it...
Note that SIGABRT seems to be implicated as the signal stopping lightdm. This
is normally due to an assertion being hit, perhaps something like an out of
memory error?
