I have screen flicker issue Ubuntu 11.04 and nvidia GTX 460M. Seems every time powermizer changes performance level I have screen flicker. Only choices in powermizer settings is "Adaptive" and "Prefer Maximum Performance". If I change to "Prefer Maximum Performance" there is no more flicker but setting does not hold. Each reboot must change setting again.

I tried adding "options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"" to modprobe.d but its not working.

Also tried adding similar line to modprobe.d which included the word "mobile" (something I found while searching) since I have ASUS G73Sw-A1 laptop but also not working.

Note I do not have "artifacts" condition as some other users - just a quick screen flicker...
