For anything using kernel 3.14+ IMO the answer to pretty much *any* gfx issue is "use stdvga instead of cirrus". 3.14 got a kms driver for the qemu stdvga (bochsdrm), so the modesetting driver and all the modern stuff such as root-less X server works with the stdvga too. And the constrains cirrus has (due to emulating existing, old hardware) are gone. cheers, Gerd
