Public bug reported:

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.
