Dear Maintainer,

This is my first bug report (using reportbug) so please let me know if
I'm not doing things the right way !

    * What led up to the situation?
Since I moved from Wheezy to Jessie, I'm experiencing random crashes of
Xserver. Most of the time, the crashes occur when I launch Iceweasel,
when I close Chromium, when I click on a hyperlink in Icedove...
Launching glxinfo in a terminal systematically crashes the system. In
every case, I have no other choice than use the power button to stop the
system and restart.

    * What exactly did you do (or not do) that was effective (or
      ineffective)?
Installing the latest nouveau driver (from Stretch) had no effect.
Loading the system with the nouveau.config=NvMSI=0 kernel parameter
didn't help either.
Eventually I created a file named local-video.conf in /etc/modprobe.d/
with this single line :
options nouveau noaccel=1
as suggested in bug #758460

    * What was the outcome of this action?
Now I can run glxinfo in a terminal, and I've had no crashes so far,
though it's probably too early to rejoice !

    * What outcome did you expect instead?
No random crashes any more, as they make the system barely usable.

Please let me know if you need more tests or information.
Thanks for your work.

Jacques
