I believe your best bet is to let Xorg probe your devices automatically 
- i.e. don't have an xorg.conf in place when starting X.

On my end this will result in the "modesetting" driver being used, which 
is the suggested driver to use for intel and i believe amdgpu systems.  
it provides full acceleration, and is under active development 
upstream.  it should also be part of the xorg-server pkg, so you don't 
need to install any additional video drivers to use the modesetting driver.
