Yeah, this is a kernel issue. There's only a small amount of VRAM available, so
the 5760x2160 framebuffer can't fit, and the kernel driver doesn't support
scanout from system memory with Raven Ridge yet.

Meanwhile, if the amount of VRAM can be increased in the BIOS setup, try that.

Thank you very much for the explanation and workaround suggestion. My choices
on this laptop are "128M" or "Auto". I think I have to poke Asus about this,
but: With Auto I do get 2048 as per dmesg and it's working.

So again, thank you. :)
