Graphics: mode settings, Wayland and more

The Linux Plumbers 2015 Graphics track is focusing on making sure that we discuss next steps regarding graphics/modesetting and standards for the next 6 to 12 months. With so much convergence taking place right now, there is a great opportunity to make things smooth and work across architectures and platforms better than ever.

We should continue the work of improving DRM drivers all around, and make them as cohesive as possible.

To make this microconference a success, representatives from Intel, NVidia, AMD, ARM, Samsung and anyone else with a GPU (or GPU experience) should attend. Interests are running far and wide for better graphics with comprehensive layer management. Let's give it to them.

Microconference complementarity

Attendees to this microconference are most likely to be interested in the Android microconference also. It would be great if those two microconference could not overlap from a scheduling stand-point.
