[SOLVED] Ubuntu screen resolution after installing nvidia driver

[oskanaan]

Dear all,

I recently installed ubuntu on my dell vostro 1500 laptop, my vga is nvidia 8400M 128 Mb. I've installed the driver using Envy, it seems to be working fine except for when I try to change the screen resolution I get the following message :
The X Server does not support the XRandR extension. Runtime resolution changes to the display size are not available.

can anybody please tell me how can I fix this, please keep in mind I am still a newbie, this is my first linux os

did you install xserver-xgl? if so uninstall it

and

post your xorg.conf located at /etc/X11/
