I recently installed ubuntu 12.04 on my asus N55SF, which runs nvidia geforce gt 555m and an integrated graphics, via optimus but after installation i found no such thing on ubuntu. i went o nvidia website and installed the driver from there(ver 259.59 i guess) after reboot, i was stuck at 640x480 resolution and my card was still undetected i reinstalled ubuntu but this time i installed bumblebee, but the system settings still shows the graphics as 'unknown' i dont know whether the driver has been installed or not, but from the 'unknown' i figure its not there. when i run sudo nvidia-settings i get this msg "You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run nvidia-xconfig as root), and restart the X server." however i can run the settings page by sudo nvidia-settins -c :8 i just want to know why ubuntu hasnt still detected the gpu? is it because bumblebee disables it?

and i forgot one v important thing..I AM A NOOB :(
