There's supposed to be a list somewhere on the xorg website of compatibility but I'll admit finding out hard data can be tricky at times.
When x starts it checks for a compatible driver so if the amdgpu driver won't work with your card, when X runs it will skip it if it's not and revert to the standard driver. You can see all of this in the x log.

Ted, The VGA controller is in the motherboard; not a separate ePCI add-on. The video card is an AMD Radeon Pro WX-2100. The amdgpu module is insalled. I don't know whether the installed amdgpu (which worked with the AMD Radeon RX-550 video card) is compatible with the WX-2100 nor how to learn whether it is. I'm joining the xorg mail list. Thanks, Rich
