nvidia - 12.04 displaying video via with vga with optimus disabled but external display not detected

I have a Dell vostro 3446 notebook with nvidia optimus. Since I do not need the capabilities of the dedicated gpu, I have blacklisted the nouveau driver and switched off the nvidia gpu with bbswitch(better battery backup).

The notebook has only a VGA output( no HDMI )

I connected the notebook to a samsung TV with a vga cable. The first time the cable was connected the TV screen was filled edge to edge with a resolution same as the native resolution of the notebook screen- 1366 X 768. Did a reboot and and now the same screen was displayed with a resolution of 1920X1080. So basically the vga output was displayed inside a 1366 X 768 window with black bands on the right and at the bottom.

I checked System Settings> Displays . The "Mirror" checkbox is disabled and only the laptop screen has been detected displayed as "Laptop". No second display detected.

I basically need the vga output to be displayed in 1920 X 1080 on the TV and ability to switch of the laptop screen.

Any help is much appreciated.

If you need me to run any tools to gather error/debug mssgs plz let me know. I have tried a few myself and here are the outputs:

xrandr

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1366 x 768, current 1366 x 768, maximum 1366 x 768
default connected 1366x768+0+0 0mm x 0mm
1366x768        0.0* 

xorg -configure

This displayed an error at the end:

Number of created screens does not match number of detected devices.
Configuration failed.  ddxSigGiveUp: Closing log Server terminated with error (2).

And here is the xorg.conf file:
