Is this a regression?
Comment 2 zhenxiang.li 2013-09-16 00:55:06 UTC 
This ivb mobile machine was tested for the first time, I tried to exchange the Kernel and X of 2012Q4RC1/2013Q2RC1, it has not been light up yet, and no message about HDMI connection by excuting the command 'xrandr'.

We found it was HDMI interface problem, close it.
