The intel-gfx list is probably the more appropriate place to ask. http://lists.freedesktop.org/mailman/listinfo/intel-gfx This is probably the relevant thread: http://lists.freedesktop.org/archives/intel-gfx/2010-March/006378.html Col -- Colin Guthrie gmane(at)colin.guthr.ie http://colin.guthr.ie/ Day Job: Tribalogic Limited [http://www.tribalogic.net/] Open Source: Mandriva Linux Contributor [http://www.mandriva.com/] PulseAudio Hacker [http://www.pulseaudio.org/] Trac Hacker [http://trac.edgewall.org/] _______________________________________________ [email protected]: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg
