Comment 64 for bug 982710

Confirmed on both 295.40 (nvidia-current) and 295.49 (nvidia-current-updates) in Precise. Graphics card 8600GT on a 64-bit AMD processor. After running Minecraft under Unity-2D for half a minute, X suddenly becomes very unresponsive and consumes 100% CPU. Simultanously the following is output to Xorg.0.log (monitored by tail -f):

[ 990.330] [mi] EQ overflowing. Additional events will be discarded until existing events are processed.

It was running fine in Lucid. Is there a way to easily try the latest NVidia drivers (currently 295.53 or 302.11b) by a .deb or PPA?
