Bug Description
My Ubuntu (14.04 LTS) desktop used to have an Intel 6700K CPU and I have been using the built in HD Graphics 530 GPU to drive 3 external displays - via DP, HDMI and DVI on the motherboard (AsRock Extreme4).
at some point, I upgraded the CPU to an Intel 7700K, and I realized that the computer can not output to 3 displays anymore.
using xrandr -q, I can only see two connections - HDMI and DP, but the DVI output is not listed, nor can be activated.
Based on this intel's page, HD630 GPU is supposed to support 3 outputs,

I am wondering if this is a known issue, or if there is a version of the xorg intel driver that support 3 outputs for HD 630?
my intel driver is provided by xserver-
thanks, let me know if there is a workaround.
