--- Comment #14 from Chris Cheney <chris.cheney at gmail.com> ---
The most recent build I tried seems to be giving more detailed DP errors I have
attached dmesg output from it. It also appears that my workaround no longer
works and that the script tells me there is no crtc available for the DP.
It appears to be repeatedly checking status of the connectors, I'm not sure if
that is supposed be happening or not.
