It would be good if that were so, but the impression I get from
the discussions around ddccontrol seem to hint that each monitor
needs a slightly different control set (ie. ddccontrol has database
to encapsulate such differences and allow for new monitors), and
I suspect things like loading the LCD video luts is outside
the VESA spec., and hence may well be different for each vendor.

If this is the situation, then it might be better if RandR just
provided the mechanism to access DDC/CI, and left all the monitor
specific stuff up to another layer ?
