I have this new asus laptop with Nvidia Geforce GTX 260M gpu. My problem is the refresh rate is low with ubuntu 9.04 and 9.10 beta even though I have installed the latest driver from nvidia web site.

I particularly need some help about why my xorg.conf file does not override the parameters that I set and does anyone know how to locate and modify the related parameters in the edid.bin file.

My xorg.conf file is below.
Thanks for the help
