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.

It is also interesting to note that prior to KMS xrandr thought the two extra ports were HDMI and after KMS thinks they are DVI. The only video physically connected is the internal LCD or at least nothing is hooked up externally. The machine physically has an internal LCD, a VGA port and on the docking station it has a vga port and a DisplayPort port. However, when I reported this bug the docking station was not connected.
