I've been wrestling with a 3D graphics driver problem for the last few
months, Perhaps its time to report it.

This appears to be some sort of bad interaction between Xorg and the
nouveau kernel drivers.  Similar bugs have been seen by others, on other
OS'es and spcifically on other graphics cards (e.g. Radeon).  Seem to be
few/no reports for nouveau.

Symptoms: X11 background fails to repaint. Eventually X11 becomes
unresponsive. Sometimes restarting X is enough to defer the problem,
sometimes a reboot is required. Usually takes a week or so for the
problem to recurr.  dmesg and /var/log/syslog fill up with vast numbers
of this:

TTM appears to be a kernel module that performs memory management of the
memory on the graphics card.  presuably X11 and/or Mesa is failing to
release unused memory.

My setup is unusual: I am using TWO graphics cards, not one:

01:03.0 VGA compatible controller: NVIDIA Corporation NV44A [GeForce 6200] (rev a1)
02:00.0 VGA compatible controller: NVIDIA Corporation G72 [GeForce 7300 LE] (rev a1)

It appears only the second one is affected, as that is where the visual
symptoms show up.

Setup has three! monitors.  Xrandr is NOT running, since Xrandr appears
to be unable to deal with the monitor setup (two of the monitors are
rotated, the third is not; this seems to drive xrandr crazy, so it does
not come up).  I mention this only because I'm wondering if the graphics
card RAM me=nagement is done differrently if xrandr is present.

Kernel is the stock kernel:
Linux version 3.13.0-40-generic (buildd@comet) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #69-Ubuntu SMP Thu Nov 13 17:53:56 UTC 2014

System has 32GB RAM.   Here is some more random info:
