Public bug reported:
Xorg (xserver-xorg 1:7.7+1ubuntu8) crashed on an Ubuntu MATE (Utopic)
amd64 system. Apport informed me of the crash when I logged in. I had
just logged out and back in.
At the time I was using this system to verify the correct behavior of
pam_env.so against another system on which it is not working. I had set
unimportant environment variables (FOO and BAR) in ~/.pam_environment,
changed them, and removed the file (which was otherwise empty). I did
this across a few graphical sessions, all within a few minutes of one
another.
I suspect that is not what triggered this crash but I'm not sure.
Recently I have some kernel messages which may or may not be related to
whatever triggered this crash:
