(Get the code!)
Hmm, if the display is being recognised by the display manager and we don't successfully turn it on, then that is a serious issue. After it gets into the "no signal" state, can you please attach the output of xrandr --verbose. It could either be that the modeline is incompatible, or that we are not programming the CRTC correctly. For the latter, grabbing intel-gpu-tools and attaching the output of intel_reg_dumper would be useful.
Also please make sure you have all the updates available (I would like if you could use xorg-edgers or raring), and attach your Xorg.0.log after it exhibits the failure.
