Public bug reported:

Binary package hint: xserver-xorg-video-intel

On the Lenovo ThinkPad X200 laptop i915 KMS incorrectly determines the
resolution of the LCD. It also for some reason thinks two DVI ports are
connected. It looks like it takes the maximum resolution from both
(1360x768 for ghost DVI and 1280x800 for internal LCD) to come up with
the resolution to use on the internal LCD (1360x800). I have included
below the output of xrandr when running with nomodeset kernel option.
Jesse Barnes mentioned he knew about this bug when I showed him the
problem at UDS and that there was a fix but not in the kernel tree at
that time. It appears the fix still isn't in at least the Ubuntu kernel
tree and needs to be added.
