My system is running on ZFS, which is not compatible with v3.11-rc5-saucy now. I'll test it once the ZFS compatibility issue got solved. This issue exists with v3.10.0-997 from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/2013-07-13-saucy. Disable internal screen might have better chance that displayport will work, but not always.

And has been seen on ThinkPad X220 for a few times, but it's mostly work with dual screen (internal+displayport) on ThinkPad X220.
