    So is this redirected direct rendering available in the ubuntu jaunty 9-4 driver?

      I don't believe so. Most of the code is probably there, but I think it came too late for the Ubuntu driver.

        Thanks for the clarification. I'll just have to wait for the next official driver release for 2.6.29 support then.

          @bridgeman: Ok, followup to the above. (Didn't wait 'til tomorrow)
          Not sure if this is helpful at all.
          I found the option. I set "UnredirectFullscreen=off" in the [Composite] section of kwinrc and did a little testing with mplayer.
          With this option the system will freeze when I go to fullscreen. 5 out of 6 times I'd get an unresized frame from the video with the rest of the screen blank, 1 out of the 6 tries I got a fullscreen frame. The mouse pointer still moved in 4 out of those tries, but everything else is unresponsive.

          When I remove the option. That is, with unredirect turned on, the results look slightly different. Now the freezes lead to a black screen. Only one of the times still showed the mouse pointer. With unredirect on I could go to fullscreen a couple of times without freezing, so seems it happens a little less frequently. (Though there were a limited number of tries of course, small sampling of data.) Once it actually froze on going from fullscreen and back to desktop.

          My harddrive was thrashing pretty badly after the last reboot, so I stopped the "tests".

          Are there logs somewhere that could be of use and which survive the reboot?

            For anyone who is *not* seeing OpenGL output composited, can you please reply back to the list with some info about your graphics chip/card/bus ?
            Radeon 9800XT AGP card

            fgl_glxgears crashes my system with no error message, just black screen and im forced to do a hard restart. glxgears works but output is not composited. Video playback with VideoOverlay on and opengloverlay off is black, and obviously not composited. This really sucks since this is the last proprietary driver for my card, and it doesn't even work correctly. Guess ill keep my eyes peeled for dri2 and gallium3d in the open source driver.

              I feel like those of us with cards <Radeon 2000 are in something similar to the "digital transition" phase going on around the world, except this time our graphics cards are becoming obsolete instead of antennas. Where's my upgrade coupons, AMD?

              Anyways, neat comparison with the composite support, it looks so much better now.

                So the "transparent splashscreen and then crazy cursor"-bug is gone? Interesting, it still exists in "9.4beta"...

                Another bug I'd really really love to get fixed soon is the support for about *any* tv-app without fighting with xorg.conf (which didn't even help me, so I have to use xawtv in a 300*200 window without XV)

                  I'm using KDE in Ubuntu 8.10, is anyone else here getting the "black flicker" bug where a quick black flicker shows up every few seconds and your system pauses (hangs?) while it's there?

                    Just switched to nvidia 2 weeks ago. Sorry ATI, you are too late.

                      For me this release is about perfect, it solve the last few bug I have until now, I have activated again Kwin composition by default. Congratulation AMD!

                      Using: Ubuntu 8.10, KDE 4.2.1, Radeon 3850.

                      Bug solved:
                      - resizing window with Kwin is now smooth.
                      - no more flicker in windowed OpenGL application with Kwin. GoogleEarth run perfect.
                      - no more black window in Wine OpenGL application. I can get SketchUp running with Wine 1.1.17

                        Kaffeine works fine (or atleast worked fine the last time I tried) if you don't use Xv. But I guess OpenGl is a viable option now even with compositing enabled.
                        The problem with tv+Xv is that fglrx horribly crashes the Xserver whenever any Xine-based media-player tries to play back an interlaced video (Bug). This can be worked around by enabling deinterlacing sometimes (in Kaffeine this worked for me for a few channels, but not all).

                          really the best fglrx release ever
                          everything works quite fine (radeon hd4870, ubuntu8.10x64, gnome+compiz)

                            @Thingy if your mouse still moves you should be able to do sysrq-key dance. e-i-u-b that should reduce the 'trashing'.
                            @Thek I am using tvtime. No 'fighting' with xorg.conf. xawtv stopped working for me a long time ago

                              Wow, glxgears now doesn't flicker so badly anymore. Instead it just totally messes up my screen, with parts of windows all over the place and only killing X helps. Never seen anything like it. Video's unchanged: xv is out of place and sometimes crashes X. Somehow my amazement over this release damped down quite quickly. Too bad no one at ATI cares to look at their Linux bug tracker, otherwise I'd complain where this belongs.

                                Somehow it seems that Catalyst starts working for me again while at the same time it stops working for other people every 3 or 4 releases
