[Bug 1409110] [NEW] nvidia binary driver leaks vram like crazy
Public bug reported:
Using the nvidia-smi tool, you can see how much VRAM the binary driver
is using for the card. However, with the current latest driver in Ubuntu
14.10, the results aren't good. Just using desktop apps (no OpenGL apart
from what Unity and Chrome naturally use), and the driver has consumed
over a GB of VRAM:

However, you can tell that this is caused by some sort of driver leak,
since if you jump to the fb console with ctl-alt-f1, and then alt-tab
back to X, the VRAM usage drops dramatically:

The upshot of this is that, right now, I have to dump to the fb console and back before using any OpenGL apps, or they often fail with OpenGL memory allocation errors.
