Ubuntu 11.10 crashes on an almost daily basis, and I'm doing various
different things when it does so, so I can't easily identify what's to
blame. Sometimes it happens when I'm in Firefox, sometimes Thunderbird,
sometimes in a Virtualbox machine running Windows Xp. But it always
happens the same way: it goes instantaneously to the black screen of
death (which looks like a logout) and thence to the login screen.
My Xorg.0.log.old has the following entries at the end of the log after
every crash:
[ 1214.793] Segmentation fault at address 0xb2536008
[ 1214.793]
Caught signal 11 (Segmentation fault). Server aborting
[ 1214.793]
Please consult the The X.Org Foundation support
at http://wiki.x.org
for help.
[ 1214.793] Please also check the log file at "/var/log/Xorg.0.log" for
additional information.

I have no idea if it's helpful, but my ~.xsession-errors has a lot of
these errors:
WARN 2012-02-21 11:03:27 glib.glib-gobject <unknown>:0 instance of
invalid non-instantiatable type `(null)'
and a lot of these:
WARN 2012-02-21 10:12:05 glib <unknown>:0 Unable to fetch
children: Method "Children" with signature "" on interface
"org.ayatana.bamf.view" doesn't exist
I'm happy to give more info, but I'd need guidance as to what's
relevant.
