I am using Ubuntu 12.04 (precise) Kernel : 3.5.0-18-generic

I am encountering a strange problem, my whole desktop has shifted to right. This happened after I restored my system, I was getting a blank screen earlier.(something is better than nothing).

For some reason it also shows my display as laptop.

Running xrandr

xrandr: Failed to get size of gamma for
output default Screen 0: minimum 640 x 480, current 1024 x 768,
maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm

1024x768 0.0* 800x600 0.0 640x480 0.0

Running lspci

lspci -nn | grep VGA

My Display on window supports maximum of 1366*768.
I do not want to reinstall everything please help.

It is cycled around as mentioned by Eliah Kagan
For correcting my blank screen issue I edited my grub file I edited this line and added nomodeset, without it screen gets all grained up.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset "

When I boot from live CD also I get the same shifted screen
