compiz segfault when logging in, affected by autofs mounts

[Jens Rydholm]

When I log in, I sometimes (about 50% of the times) suffer a crashing compiz. The symptoms are that the screen flashes quickly black with a diagonal (top left to bottom right) white band a few times. After a while, the screen sometimes freezes, and sometimes shows the files on my desktop (but no other controls).

I use a HP Pavilion Laptop with a small hard drive. I use autofs to mount additional directories, one per user, from a NAS box to which I connect over my wireless network. Here is my autofs configuration:

$ tail -1 /etc/auto.master
/mnt/marauder/homes /etc/auto.home

$ cat /etc/auto.home
* marauder:/volume1/homes/&

These mounted directories are not used as user home directories directly, since I want my laptop to work without access to the NAS. Instead, I have replaced the various file-storing standard directories with symlinks into the mounted directory. So for the user 'spacejens', I have:

$ ls -l | grep marauder
lrwxrwxrwx 1 spacejens spacejens 40 2011-10-22 17:16 Documents -> /mnt/marauder/homes/spacejens/Documents/
lrwxrwxrwx 1 spacejens spacejens 35 2011-10-22 17:23 Music -> /mnt/marauder/homes/spacejens/Music
...

I have successfully avoided the problems by ensuring that before I log in to the graphical environment, I use Ctrl+Alt+<number> to get to the console login prompt, log in there, and execute e.g. 'ls Documents' to make sure that the autofs directories are properly mounted. After I have done this, I have been able to log in to the graphical environment without problems.

The problem still remains. I am currently working around the issue by using "Ubuntu 2D" from the login screen.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. Compiz, in particular, is in heavy development and this bug may have been fixed in the development version of Ubuntu (12.04) if not on the current 11.10 release. If you are able, it would be of great help if you could confirm if the bug still exists by testing a livecd (available at http://cdimage.ubuntu.com/daily-live/current/). When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue. Please keep in mind that the development version (12.04) is not suitable for daily use - please only use it for testing purposes.

Thank you for your help and patience.
