I have an Alienware laptop with a GeForce Go 6800 Ultra card. I have been using the G02 driver. The lats two driver update from Nvidia do not support this card. I have to install the G01 driver to get graphics working. I have seen problems like this in the past, but it was always fixed on the next driver update, this is now two in a row. The G02 is for 6800 and higher, and the G01 is for all cards before the 6800.

This is from the Xorg.0.log with the G02 driver installed.
