RandR Documentation

In addition to the RandR X protocol, an official configuration utility (named xrandr) is maintained in the freedesktop git repository.

• Protocol specification
• RandR 1.2 overview from Debian
• X Configuration from Ubuntu
• Documentation from Intel on setting up dual head configuration with RandR 1.2
• XrandR 1.2 HowTo from ThinkWiki
• A Newbie's Guide from Phoronix
• A short how-to on writing an X.Org driver, updated to include RandR 1.2.

For Historical (only?) value:

• The usenix paper from 2001 describing RANDR 0.91 and it's motivations.
