<pre>Please, let's tackle that drm_cflush_page() issue separately, i.e. the lag. I
think that is a kernel bug fixed in recent kernels.
Can you double check that everything is fine but just too slow? In particular,
rearranging the screens (modulo mutter blowing up sporadically when it tries to
dereference a NULL pointer - not my bug! ;-)?</pre>
