Title:
Nouveau TTM Failed to find memory space for buffer
Status in xorg package in Ubuntu:
Expired
Bug description:
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:
