I've upgraded a few laptops that from Ubuntu 8,10 to 9.04. These have either Intel 915 or 945 graphics chips. .
The xvideo performance has gotten much worse after the upgrade. The video is jumpy at 720p or 1080i where it wasn't before. I'm guessing that this is because of the Intel Xorg driver which moved from 2.4.1 to 2.6.3 in the upgrade. Both Intel chips use the overlay xv driver, and I made sure that XvPreferOverlay is on in xorg.conf. xvinfo confirms that the overlay (not textured) is the default xv port as on 8.10. In either case xvmc is disabled, and I don't really see any significant differences in the Xorg logs. I can post them if anyone thinks that would be useful. Is there something else I'm missing? The performance is just too bad to be used on on 9.04 with the usual set of media players at the higher rez's. _______________________________________________ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
