To me this looks like it could be an Ubuntu Unity issue.

What is the otuput of xrandr when the problem occurs?

Does it also happen if you make the corresponding changes in the Unity / GNOME display configuration tool?

samit vats, Ubuntu 12.10 reached EOL on May 16, 2014. For more on this, please see https://wiki.ubuntu.com/Releases.

If this is reproducible in a supported release, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal:
ubuntu-bug xorg
