Hi @edrickhong , do you mind to help do a little debug? Could you please help to check if Dri3WindowSystem::IsDevicePresentable returns true? If not, could you please check what is pPciBusString? Thanks in advance!

Debugging now. Dri3WindowSystem::IsDevicePresentable returns false. it doesn't hit the for loop because providersNum is 0

Answer 3 · 2018-07-23T11:37:28.000Z

Just to be clear, a valid pProvidersReply is returned. num_providers is 0

I almost forgot. If it helps, this is also running under XWayland, not X11 directly
