Mainline kernel only has experimental support for compute on Vega10, no support
for displaying anything.
You need to use Alex amd-staging-drm-next kernel or wait for 4.15.

That's because in this configuration the BIOS brings up your Vega10 for output
and X just sticks with the Vesa driver because it can't find anything else.
To use a Vega10 in a desktop machine you need development packages of the
kernel, mesa and DDX.
Pre compiled user space packages for Ubuntu can be found here for example:
