Derek, to advise, please do not compress/tar files and attach them, as it makes it difficult for folks to review them quickly. Despite this, the issue you are reporting is an upstream one. Could you please report this problem following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel to the appropriate mailing list (intel-gfx)? Please provide a direct URL to your post to the mailing list when it becomes available so that it may be tracked.

This results in part of the desktop being inaccessible, until the external displays are unplugged, and then plugged back in. Sometimes, Xorg will also back down to one monitor.
