dmesg withe debug enabled, plug in dp after boot.
dmesg - kernel 4.0.5
* Laptop model: DELL E7440
* Linux distribution: Gentoo x86_64
* Graphics: VGA compatible controller: Intel Corporation Haswell-ULT Integrated
Graphics Controller (rev 0b)
* Arch: x86_64
* kernel: tested with all 4.0.x kernels, the problem appears in all versions.
* xorg-server: 1.16.3-r1
* xf86-video-intel: 2.99.917
* mesa: 10.4.2
* libdrm: 2.4.59
I use dp to connect to a external DELL U3415w(3440 x 1440 at 60Hz). No matter
how I plug in the dp port, after boot or before boot, the monitor doesn't give
any picture, the monitor says it will turn into power save mode. It used to
work with 3.14 kernels.
And it works with my office's DELL U2713HM(2560x1440).
Tried the same cable and same monitor with a MacBook, everything works.
Tried to merge some fixes in the git but found no solution.</pre>
