xrandr -q --verbose with screen 1 connected

I have two external screens, say screen 1 and 2. Screen 1 have HDMI input and
screens 2 is connected via HDMI-to-DVI adapter.

With kernel 3.12 screen 1 is not recognized on connect anymore. Booting kernel
3.11.9 makes it work again.

When I connect screen 1 nothing appears not in Xorg.0.log nor in dmesg
