    Spectacular Crash - think it was the nouveax driver.

    Was using dash to search and machine froze. Left it a while and then screen took on a pop art random look.

    Machine then rebooted. Not sure how to bug this but in kern.log was this.

    Multiple entries of this Mar 20 14:58:13 philcb-desktop kernel: [ 3113.174777] nouveau E[ PGRAPH][0000:01:00.0] ILLEGAL_MTHD
    And then the following. Any advice how to bug this.
    Code:

    Re: Spectacular Crash - think it was the nouveax driver.

    Just curious -
    if you only restarted/logged out once since then in ~/.xsession-errors.old do you have something like
    nouveau: kernel rejected pushbuf: Cannot allocate memory
    (if done more than once then .xsession-errors.old isn't any value anymore

    Not got that error but a few of these on various apps. Fatal IO error 11 (Resource temporarily unavailable) on X server :0.

    Or could it be a Unity crash?

    Those are normal, from logging out/restart/shutdown
    I guess your issue is diff from what I've seen with certain nvidia chipsets, using the Dash with the default option of active blur can on occasion lead to message I posted & unpredictable results graphically.

    As far your specific, (or thereabouts), I believe I've seen that in several bug reports - here's a more recent one
    https://bugs.launchpad.net/ubuntu/+s...l/+bug/1097178
    or
    https://bugs.freedesktop.org/show_bug.cgi?id=54786

    (not to say the ^ is exactly your's..
