            Bug ID: 63651
           Summary: DVI connected monitor only sleeps

    Kernel Version: 3.11

I have a Lenovo ThinkPad t430i with a dock. The dock has one DVI and
DisplayPort connector each. When using kernel 3.10, I use all three displays.
However, after upgrading to linux 3.11, the DVI connected monitor will only
enter sleep mode when connected (from either non-X tty or when X is running).

uname -srvmo:

Linux 3.11.2-1-ARCH #1 SMP PREEMPT Fri Sep 27 07:35:36 CEST 2013 x86_64
GNU/Linux

Output from xrandr shows that all three displays are present, but I receive
"xrandr: Configure crtc 2 failed" when I try to manipulate the DVI output:
