Bug Description
I have a Dell N4010 laptop, with Intel Core i3 and Intel graphics.
Ubuntu installation uses i915 driver.
Everything is working fine, but when i plug an external monitor to the VGA-OUT port, it displays image, i can configure to use it as "Clone" or "Extended" monitor, but in every case the image is always wobbly, trembling.
I had fixed this issue before, on Ubuntu 11.04, using a custom kernel compiled by comebody i've found on a similar bug report for that version.
