How to change 3D game resolution on 12.10 64bit with nvidia graphics driver

I have problem with nvidia graphics driver opensource and proprietary ! Can't change resolution on 3d games and there's a bug there are no kernel sources installed and thus jockey can't install proprietary drivers.

I can't change resolution while on games fullscreen.
I tried to install proprietary driver and i couldn't plus i couldn't login to ubuntu it showed only the desktop photo no dash no nothing.
-tried to install kernel sources and blacklist+remove Nouveau drivers and then installed the proprietary drivers i hope succesfully.
-The problem is the same i can't change resolution on 3d games while on fullscreen.

I've installed the sources and be able to install the proprietary nvidia drivers but the problem remains,
look what i got in the output of a 3d game exited while i tried to change resolution:

X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 150 (XFree86-VidModeExtension)
Minor opcode of failed request: 10 (XF86VidModeSwitchToMode)
Value in failed request: 0x25b
Serial number of failed request: 497
Current serial number in output stream: 499

I'm giving you more details about my system:

The output of:
sudo lshw -C display; lsb_release -a; uname -a

Is the following:
