Bug Description
https:/
Summary: a patch included after upstream kernel 3.10 (and for ubuntu, whatever was used in the live iso) restricted DVI-D single link connections to 165MHz. Some monitors, which worked before that patch via an overclocked single link connection stopped working. This patch lets the user specify modes manually that are higher than 165MHz "at their own risk".
I've tested the patch in the upstream bug against the current (as of 19 Jun 2014) git trusty kernel tree and everything seems to work fine. While the patch listed on the above bug won't apply with git-am, it will apply as patch -p0.
I have it patched on my local branch, and can send a diff if it's needed.
