Hi Bryce -
Two X sessions. I knew that description didn't seem good; I'll update
it.
I cannot reproduce it at will, or at all, so far. I've had problems a
number of times when switching between two X sessions, but certainly in
a minority of those events. Most of them I've considered bug 966744,
happening when one session had been idle long enough for DPMS to kick
in. X would stop displaying anything, but no crash or lockup triggered
apport.
I had a different strange problem yesterday, still under xserver-xorg-
video-intel 2.20.6-0ubuntu1, where X slowed way down and eventually
stopped responding. I haven't tried to file that, because, so far, no
problems have happened yet under xserver-xorg-video-intel
2.20.7-0ubuntu1. Hoping the problems were transient.
Happy to clarify these awkward descriptions as needed. Thanks!
** Description changed:
- I had two different user sessions, running on two vts, when this crash
- happened. This report was uploaded after a reboot. I could ssh into
- the system, but the screen was black and unresponsive. Thanks.
