Bug Description

Ubuntu 11.10:
unity: 4.20.0-0ubuntu2
compiz: 1:0.9.6+bzr20110929-0ubuntu1
xorg: 1:7.6+7ubuntu7
linux-image-generic: 3.0.0.12.19
lightdm: 1.0.0-0ubuntu4

Since today’s updates compiz does not load any more. When i try to log into unity-3d it quickly blinks with the following error message:
compiz --replace &

I just tried to reproduce the bug with an older kernel and was successful.
Same Error happens with Kernel 2.6.38-11-generic which was working perfectly with natty.

var_log_lightdm.20110104.851345.tgz Edit (6.2 KiB, application/x-tar)

after a day testing, I've finally been able to reproduce but still didn't find a pattern to do it reliably. It seems to happen after a system upgrade.

lightdm logs are attached.

I noticed that each time it happens there is the following message in syslog
Oct 4 23:55:32 white kernel: [ 175.787767] init: lightdm main process (909) killed by ABRT signal

I'll attach the list of packages that have been updated to next comment.

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 system works around the problem.

Philipp Meier (meier-philipp) wrote on 2011-10-05:

#19

At least for me it does not sound familiar to bug #864054 as everything from update to synaptic to external drives is working properly. Just the 3d-acceleartion did stop and therefore unity-2d is running. But the hardware is fully capable of 3d acceleration and a different kernel did not help at all.
The bug was once fixed by an update of lightdm as you can see above.

Robert Ancell (robert-ancell) wrote on 2011-10-06:

#21

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 killall -SIGABRT lightdm
You will have to kill the X server after this and run sudo start lightdm to recover.

The question is, what has caused the lightdm daemon to crash and why hasn't apport restarted it / gone into failsafe X mode?

Robert Ancell (robert-ancell) wrote on 2011-10-06:

#22

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?

Jean-Baptiste Lallement (jibel) wrote on 2011-10-06:

#23

no trace of an out of memory error here, after boot and this error, the system still has 1.6GB of RAM free and no kernel message that would suggest a memory failure.

Philipp Meier (meier-philipp) wrote on 2011-10-06:

#24

same here does not look like it has not enough "real" memory. I do also have around 1.7 GB of free RAM.
any way to make sure it really is a lightdm problem?

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 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 didn't work - after restarting the X session the problem persisted. I had to completely reboot the machine to fix it.

Since this bug is marked fixed, should we open another one?
