I currently run 2 monitors with separate X-screens for each, I have no trouble launching apps on any of them.
When I try to play vulkan/dxvk games. I get “CreateSwapChain():
The selected graphics queue does not support presenting a swapchain image”. No such thing happens with just 1 X-screen. Opengl apps launch just fine with multiple X-screens.
I have modesetting enabled.
