I’m trying to get a demo running on Fedora Core 28 with Hades Canyon NUC (Radeon RX Vega M) I installed Mesa 18.2.0-rc5 to get graphics working, OpenGL core says version 3.3

When I launch with -opengl3 I get the following error:

Any ideas?

Solved this myself.
Clue was glxinfo | grep AMD returned nothing, so the Vega driver was not being used, I think because I was on the wrong HDMI port.

In any event, glxinfo | grep AMD should show “OpenGL renderer string: AMD VEGAM” when everything is working.
