Compiz - Slow scroll, resize and video playback problem

[Blueshift]

I finally got compiz working on my IBM - X31 featuring the ATI Radeon 7000 (Model M6). I have however a few questions on improving the speed and usability of the compiz add-on.

First off I was wondering if anyone have the slow resize of window problem and the slow scrolling problem? And is there any way of optimizing this issue? Another big problem I have is when I'm watching a video or playing a videostream over the Internet. There is a lot of flickering going on and after some time the image totally disappears! A similar effect occurs when using Google Earth, as you zoom in a lot of flickering occurs!

I have installed Compiz version 0.3.6 from gandalfn: http://gandalfn.wordpress.com/howto/...-aiglx-on-edgy

I have edited the xorg.conf file in light of:

Any tips or help on this would be much appreciated! :)

The slow scrolling and resize issue is normally only seen with ATI. You might have better scrolling and resizing using Xgl. Check this forum for a patch from stjepan to make it even quicker.

The video problems are known about and are something which needs to be fixed higher up and is not really something that can be fixed in Compiz.

I'm willing to go give it a try, if its possible to find a guide on how to install XGL on Ubuntu Edgy. According to
http://gentoo-wiki.com/HARDWARE_Video_Card_Support_Under_XGL
This might actually be possible with the Radeon Mobility 7000

The Radeon Mobility 7000 is supported via Xgl using
Driver: DRM_RADEON kernel driver & xf86-video-ati-6.5.7.3

I'm guessing this driver corresponds to the standard Open Source driver found in Ubuntu and the one I'm currently using?

Found the XGL patch at
http://www.go-compiz.org/index.php?title=Patch_to_make_XGL_faster

The video problems are known about and are something which needs to be fixed higher up and is not really something that can be fixed in Compiz.

So this means its a software problem in the video players or what? What about the Google Earth issue? I have tested it with Totem, VLC, MPlayer and Xine. Xine is the only one operating fairly normal, but I'm not able to play streams from the Internet via this player.

Yes, you will need to compile from source if you are going to use the patch. Ask on another thread if you have problems there.

I am sorry, I do not know much more about the video issue other than its a problem with the drivers/server which is known about.

First, slow resizing is pretty typical with any composited window manager. You should set the "Default Resize Mode" to something other than "normal" in the "resize window" plugin. I would recommend Stretch or Outline.

2nd, flickering video playback when using the Xvideo is also normal with any driver that doesn't support textured video and, instead, uses the Xvideo overlay. Newer versions of most (all) open source drivers support. In addition, any driver that uses Xorg's direct rendering infrastructure (such as the open source radeon driver) will have serious issues showing windowed opengl applications at the same time that compiz is running. This is the case with Google Earth.

Third, compiz 0.3.6 is *ancient*. If you are using Edgy, you should seriously consider updating to a newer version of Ubuntu.
