I upgrade my system from 4th gen to i7 8700k with gigabyte z370n. But my graphics card (Intel UHD 630) can not load properly.I am running Ubuntu 16.04.

I have tried to add alpha_support to /etc/default/grub but it didn't work. And I have tried intel-graphics-update-tool which also didn't work.

How to fix it?
