[Bug 1260741] Re: Mini Displayport on Lenovo Thinkpad T530 isn't recognised

 

Kernel tested, and nothing has changed. Note that the second link you
provided is the 3.13 kernel for Trusty.

Since this issue involves specific hardware that I own, I'm willing to
do testing on this issue, if more experienced people can provide me with
the tools to test.
