816	New display server	Jiri Svoboda	Jiri Svoboda	"Work on new display server as a replacement for compositor is in progress at [https://github.com/jxsvoboda/helenos/commits/gfx]

This is the first step of overhauling the graphics/UI stack. Here's some of the high-level goals.

  * An abstract rendering API and window update protocol that can be used both for App <-> Display server and Display Server <-> Display Driver communication and other things
  * Make it possible to conserve memory (compared to all windows being always fully memory-backed)
  * Make the memory retention and communication mode a decision of the display server, not an inherent property of the display protocol / API
  * Display protocol should explicitly denote frame boundaries and frame timing
  * Support a wider range of pixel formats (<32 bpp, >32bpp) including text mode
  * Better support for multi-seat and multi-point

The scope of this ticket is achieving rough parity with current compositor-based solution."	enhancement	closed	major	0.11.1	helenos/unspecified	mainline	fixed	ui				#652
