Ubuntu 16.10 DVI only works with VGA adapter

  • 772

Using Ubuntu 16.10 Intel 945GSE graphics

Using nomodeset in GRUB, the DVI works with a DVI cable and the DVI-HDMI also works, all with a low resolution (i.e. safe-mode)

When NOT using nomodeset, the DVI port only works with a VGA adapter but in full 1920x1080.

I want to use the DVI port as DVI or with an HDMI adapter so that I can connect to a TV to use Kobi with an iptv subscription.

Steps to try and fix: Tried with a different monitor Installed and used the INTEL GRAPHICS UPDATE TOOL FOR LINUX* OS V2.0.4 played with xrandr

drivers
