Comment 29 for bug 507233

I no longer can use the 173 version of the NVidia driver without severely impacting overall performance, and the latest (Lucid, version no 195) is buggier than ever -- crashing on AC and battery.

Also, Meng, I tried using your trick but it broke my X display completely. It couldn't find a screen. Do you think you could post your xorg.conf so I could see exactly what it contains?
