[$] LCA: The X-men speak

Linux.conf.au 2013 in Canberra provided an interesting window into the world of display server development with a pair of talks about the X Window System and one about its planned successor Wayland (a talk which will be the subject of its own article shortly). First, Keith Packard discussed coming improvements to compositing and rendering. He was followed by David Airlie, who talked about recent changes and upcoming new features for the Resize, Rotate and Reflect Extension (RandR), particularly to cope with multiple-GPU laptops. Each talk was each entertaining enough in its own right, but they worked even better together as the speakers interjected their own comments into one another's Q&A period (or, from time to time, during the talks themselves).
