You are not looking for alternatives, because having OpenGL support doesn't increase rdesktop performance because it doesn't use OpenGL at all - so how could it help? I'm not qualified on the affects of having this "DRI" thing or not, but Geode doesn't have it and no-one is rushing to do it, perhaps even not possible (or needed?). Increasing performance most probably involves actually profiling what and why is slow and improving that in the xf6-video-geode driver code and xorg-server EXA code. Helping hands much welcome there.. rdesktop is probably pretty nice and relatively easy case for performance fixing, because it probably uses quite a limited set of drawing commands for RDP protocol as far as I understand and therefore a limited set of code paths and drawing ops to improve. If you'd have some sysprof logs to go along with a too slow rdesktop session (that isn't network bound) and added that as an attachment to a bug about rdesktop being slow on Geode (there's a Driver/AMD bugzilla component for xorg product), then that'd be some progress :) Some more information is for example at http://lists.laptop.org/pipermail/devel/2008-December/022034.html http://lists.laptop.org/pipermail/devel/2008-December/022036.html Regards, Mart Raudsepp _______________________________________________ Xorg-driver-geode mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-geode
