Add Option "DRI" to allow selection of maximum DRI level. (v2) http://cgit.freedesktop.org/nouveau/xf86-video-nouveau/commit/?id=6296145 "exa accel supports both DRI2 and, if the kernel supports rendernodes, also DRI3. However, DRI3 still seems to have some bugs on current implementations, ..." Mario, what are these "some bugs on current implementations"? _______________________________________________ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
