After the installation of the Ubuntu 16.04 LTS and the login to my account is not display anything. Only the classic wallpaper of the Ubuntu and one message error which is hidden after some seconds. Ι have the same problem and with the live CD.
I had the same problem, now downloading another ubuntu based distro to see if that works. My system:
Skylake based M/B: GA-Z170X-UD5, i7 7600, GeForce GX 980 Ti
I noticed that the installer would sometimes only recognise the onboard graphics, so I had to replug the monitor cable, when I checked the error report it was clearly related to the graphics card. I guess it's some driver issue.
