However, as not much else has been discussed yet in regards to RandR 1.4, it would be unlikely for any of this to appear with the next release (X.Org 7.5 / X Server 1.7). Today's patch just defines the per-output DPMS portion of the RandR protocol but does nothing in regards to implementing the support within any driver. We are also just under two weeks away from the X Server 1.7 feature freeze. Also still missing from the Resize and Rotate extension is GPU object support.
The current version is RandR 1.3 and it provides panning support and other minor improvements. This version was introduced with X Server 1.6 and most of the open-source drivers now implement the RandR 1.3 panning support. For more information on the X.Org Resize and Rotate extension, read The Newbie's Guide To RandR 1.2.
