I'm using 4.4.0-79-generic and experiencing this problem (Ubuntu Server 16.04.2)
$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09) This is a Shuttle XS35-V2 with a Pentium G2020 CPU. If booting with the monitor plugged in, it shows the console login. If connecting a monitor after the boot, the monitor shows no input signal.
