NVidia promised to do this over two years ago and have yet to deliver a driver
that supports XRadR 1.2. Phoronix reported last week that this is now a top
priority for nVidia and nVidia X11 driver developers have posted to the nV
News forums that it is now a priority. But they have not given an estimated
date so we may see this sometime in the next few months but maybe not.
AMD's proprietary video drivers have supported this for a few months now so
newer versions of their driver should work. So if you are using an older
AMD/ATI driver you may want to upgrade (also the newer versions of the driver
are reported to be of MUCH higher quality).
Most of the open source drivers have had XRandR 1.2 support for some time now.
