I have one of those. The dock DP lane is "hijacked" to fit the FHD eDP screen. In the BIOS (and in Windows) the signal is duplicated between the non-existent LVDS and DP, consuming more power. However it works very well in Linux with a small patch to the i915 module that disables the LVDS lane and forces DP-3 to be detected as eDP. I tried doing the same in coreboot, playing with the source code, but couldn't figure out how to. It would be great to have the setup working "natively" -- coreboot mailing list: [email protected] https://www.coreboot.org/mailman/listinfo/coreboot
