Screenshot of log output

I came in to work this morning, to find two of my four monitors blank,
and the other two showing the attached log output (screenshot only,
because I can't find it in anywhere on the filesystem).

/var/log/messages contains errors of the form:

nouveau E[ PGRAPH][0000:01:00.0] TRAP ch 7 [0x007f730000 cubicgrid[18458]]
nouveau E[ PGRAPH][0000:01:00.0] GPC0/TPC0/MP trap: MULTIPLE_WARP_ERRORS MEM_OUT_OF_BOUNDS

cubicgrid is my screensaver (part of xscreensaver)

Here's some more information that may or may not be useful. If you need
any more, just ask and I'll see what I can do:
