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.
