HI Everyone,

I have a Acer 5951G notebook
nvidia Geforce GT 555M 2Gb
i7 2630QM
HM65 express chipset

After i installed the driver and the CUDA toolkit i am having a problem on startx (followed http://www.backtrack-linux.org/wiki/...A_On_BackTrack on installing the driver and toolkit). I tried adding BusID to xorg.conf however i made me run into black screen after startx. Although i know X is running because when i press CTRL-ALT-DEL and then Enter i can shutdown properly. I think this problem was caused by my monitor is connected to the Intel's graphic card. So when I use the Nvidia's graphic card nothing's output to the monitor. If i delete xorg.conf I can successfully boot into GNOME. If i change Grub's setting to i915.modeset=1 i will run into black screen while booting. Can anyone tell me how to make my Nvidia graphic card work properly?
