I am trying to install 16.04 Ubuntu Server on a machine with a Gigabyte H270 chipset motherobard and an i5-6400. Server installation runs smoothly without any issues.
On the first boot though the screen turns blank after trying to load VESA VGA (can't remember the exact line). I could boot into a nomodeset shell. In there I installed xorg and gnome as well as gnome system tools and gnome app install (as per manual we use for slightly different machines). Another reboot yielded the same black screen and now even the nomodeset shell doesn't work as the screen flickers with 2 second periods. After installing openssh-server via the root recovery shell I can log in via putty from another machine on the network.
The next information is partly based on a similar topic here: Skylake Integrated graphics not working on 15.10
Via putty I tried to figure out what's wrong. dmesg | grep -i i915 gives me a bunch of stuff. Warnings and 1 error. Interesting stuff:
[ 5.557010] [drm:vlv_enable_pll.isra.85 [i915_bpo]] *ERROR* DPLL 0 failed to lock
[ 7.305174] i915_bpo 0000:00:02.0: No connectors reported connected with modes
Also lshw -enable pci -class display yields:
*-display

So the graphic driver doesn't load and the display isn't claimed. Might that be because I am in a terminal only putty session? inxi -b tells me:

I am not sure what's wrong. The X Server doesn't seem to run at all, as there is no log in /var/log/ or ~/.local/share/xorg/.
Not sure what's going wrong really ... anyone care to enlighten me how to debug this?
