Per my understanding the decision of X server 1.12 vs 1.13 is undecided. Assuming 1.13 could ship (meaning AMD does a special Catalyst like they always do), DRI2 offloading without dynamic switching could be supported for Intel UXA + Nouveau setups.
In terms of exposure to the user, David Airlied put forth the following comment [1][2]. "the first implementation will just involve setting an env var, like DRI_PRIME=1, then I'm hopefully going to add a gnome-shell extension to make the same possible from a launcher or some sort. After that people can do what they like ;-)" X server 1.14 should have dynamic switching and my assumption is that 13.04 will ship with it, but the opportunity exists to have some level of hybrid graphics support for 12.10. However, the plans to ship Intel SNA kinda interferes with this since Prime is UXA-only at the moment [3]. I have no idea if SNA Prime is even feasible for 13.04. If SNA is not deemed ready for 12.10 due to bugs or a perceived immaturity, UXA Prime will ship (assuming 1.13). - Eric [1] http://lists.x.org/archives/xorg-devel/2012-June/031519.html [2] http://phoronix.com/forums/showthread.php?71422-DRI2-Offload-Slaves-Output-Slaves-For-September&p=267147#post267147 [3] https://lists.ubuntu.com/archives/ubuntu-x/2012-June/001192.html _______________________________________________ Mailing list: https://launchpad.net/~hybrid-graphics-linux Post to : hybrid-graphics-linux@lists.launchpad.net Unsubscribe : https://launchpad.net/~hybrid-graphics-linux More help : https://help.launchpad.net/ListHelp
