[Matthew Glennon <mglennon@xxxxxxxxxx>]

I'm now running Ubuntu 15.10.
GeForce 9400GT with drivers 304.
After the upgrade to 15.10 my graphics performance declined, so I attempted
to purge the 304 drivers and move to 355 but I experienced a login loop.
Purged those and tried 352 with the same results, so I went back to drivers
304. It seems (so far) that the purge and reinstall solved some of my
performance issues, but I still get the random black squares where content
should be. I will try to capture it with my cellphone camera when it
happens again and submit it.
