Public bug reported:
Running my own build of the natty 'master-next' kernel branch
(2.6.38-6.33 at SHA1-ID "5754cb"; based on linux 2.6.38-rc7), the
default unity desktop session makes compiz crash immediately upon login
(100% reproducible):
compiz[1388]: segfault at 20 ip 00007ff0cee9702a sp 00007fffc50a9580
error 4 in i965_dri.so[7ff0cee6b000+ac000]
The crash does NOT occur when running the natty main kernel
(2.6.38-5.32), so this appears to be a regression caused by the master-
next branch.
Note that I the gnome-panel (classic) session works fine. Also, after
unity/compiz crashes, I can then switch to a VT and launch gnome-panel
and compiz manually... In that state, "unity --replace" does make the
same crash occur immediately. (Effectively, only unity seems to provoke
this compiz crash, and it always does so).
