Thanks for the tip.  Looks like a lot of information here but I don't
really understand it.  Xorg seems to have unloaded the radeon driver...?

Graphics:  Device-1: AMD Kaveri [Radeon R7 Graphics] vendor: ASUSTeK
driver: N/A
           bus ID: 00:01.0 chip ID: 1002:130f
           Display: x11 server: X.Org 1.20.4 driver: ati,vesa
           unloaded: fbdev,modesetting,radeon resolution: 1600x900~N/A
           OpenGL: renderer: llvmpipe (LLVM 7.0 128 bits) v: 3.3 Mesa 18.3.6
           compat-v: 3.1 direct render: Yes

Where would I find "AMDGPU" and how would I get Xorg to use it?
