Yep, I'm in xv. Not running a compositor, desktop effects are disabled. I'm quite savvy with mplayer (well, I don't compile svn releases every day like some people), having successfully manipulated it to run 1080p HD videos on this crappy video card without hiccups in windows, but I'm not having similar results under the open-source drivers.I'm still surprised that you're finding image quality worse with the open source drivers than with fglrx. AFAIK most people have opposite results. Are you sure you're using -vo xv with mplayer ? Do you have a compositor running ? I believe Ubuntu enables desktop effects (ie Compiz) by default if the driver supports it. If Preferences -> Appearance -> Desktop Effects isn't set to None, try it there.
Same output, for the most part.Run hwinfo --gfxcard in the terminal to find out if this is also happening on xpress 1100. spinsane
interesting, in Ubuntu 9.10, I'm occasionally getting noticeable vsync lines. Window movements and transitions are a little on the choppy side.Weird. I got a 200M on my laptop running radeon and it works fine. Videos have a high CPU usage, but I guess that's expected from an integrated graphics unit (but even with the CPU at 800MHz I rarely get dropped frames). 3D performance is not that great (last time I bothered to compare it was about 50% that of Windows performance in 3D), but things like Compiz and some open source games (and recently even some 3D games under WINE) run fairly well. 2D performance and video quality are actually much better than fglrx could ever give me, and since 2D rendering and videos are the main uses of this laptop for me the driver is "good enough".
I don't use this laptop too often at the moment, but I think I'll find some time to put another boot of linux on here. Probably Ubuntu 9.04, downgrade the kernel and X to compatible degrees, and then compare the difference.
