[Bug 1560524] Re: Latitude E7470 crashes in DRM driver after connecting to DELL EPORT docking station
Installing 4.4.12-040412-generic from http://kernel.ubuntu.com/~kernel-
ppa/mainline/?C=N;O=D and I am able to run a 4k screen through the dock
and DP with the internal screen running, which I couldn't do
successfully before.
Worth testing if you also have this problem. Also check your BIOS version
sudo dmidecode |grep 'BIOS Information' -A5|grep Version
Version: 1.5.3
Note that I also applied a dock-specific firmware update while in windows, though it isn't entirely clear if it was a windows driver or if it changes any firmware stored within the dock ( http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=WNV4C )
