    I am really fed up waiting for a decent driver, each month there are more bugs than fixes, I can tell amd really wan't to keep there customer's. I gave them a chance as they were down and started to support linux, but enough is enough 6 months have passed and drivers are still crap.To add insult to injury the new cards are out before they even got the last ones working(3870) this is only going to slow them down even more.
    People keep saying about the compiz bug, but nvidia or intel users do not have it. my old fx5900 runs better than hd3870 and has quarter of the ram.
    Goodluck AMD your need it.

      Oh well the gras isn't always greener. I encountered some serious issues with Geforce 8800 an d9600 cards, not to mention the poos build quality

        Let's set the record slightly straighter about this bug.

        Compiz is a compositor, it tells applications to render offscreen and then composites (blends, combines, whatever) into an image and presents it to the screen. The application is still told where it is on the screen, it is just that most 2D clients render to the offscreen pixmap.

        The direct clients of the current driver (OpenGL and Video) render directly to the framebuffer (the screen). Compiz (as an OpenGL application) renders to the framebuffer. The "flickering" that people are talking about is actually two openGL clients rendering to the same part of the screen.

        The COMPOSITE extension is an all or nothing option, the compositor assumes that all windows are compositable, and there is no way for the driver to say that the window shouldn't be composited. I am hoping that COMPOSITE can be extended to provide hints to the compositor that for whatever reason (overlay, etc), an application can't render offscreen and so the compositor should provide all the details needed for the rendering to occur properly. Currently we can't do that.

        To solve this completely, *ALL* clients must support the COMPOSITE extension fully. The NVidia drivers support this currently, some xV clients support this as well. None of the DRI based 3D drivers support this. DRI2 is adding infrastructure to support COMPOSITE fully (through the so-called Redirected Direct Rendering), but that is at least 6-9 months away from the next XOrg release.

        I am not providing a timeline as to when full COMPOSITE support will be added to the driver, but I wanted to allow people to understand what is happening rather than making unfounded comments.

        Other compositors (like metacity) do not try to re-render the whole screen with OpenGL, and so the behaviour is a lot less noticable - but you can still see that the OpenGL applications are not given clipping information, so will overwrite windows that pass infront of the application.

        Regards,

        Matthew
        Thanks for clarifying. Hopefully we won't need to wait long for the full COMPOSITE support

          is it just me or does playback of 1080p lag with cat 8.6 (hd3870)? i gave big buck bunny a whirl n there was initially no sync between sound n video then it just froze... grrr

            I'm not using compiz and nothing similar, and i can't resize a window of programs used to see TV, like xdtv, because when i resize the window i can't see the image, i only see like interferences. This not happens on 8.5 driver.

            This is the worst driver that i've installed! My X broken when i open Mplayer!!! I'm back to 8.5

              Dell Inspiron 9400 with Ati X1400 videocard here.

              I tried to upgrade from 8.5 to 8.6 drivers, and after some hours of various use, mainly in the office, i noticed some unacceptable things like:

              - hanging when exiting from 3d accelerated screensavers (had to kill the apps through ssh connection from another machine)
              - problems on video playback (mplayer worked, vlc and xine and kaffeine didn't work)


              I reverted to 8.5 drivers, which had not these problems.



              Now, i always respect other people's work. Anyway, i'm really starting to be really FULL about the way linux users of Ati cards are regarded, by Ati company.
              I love this laptop, i love the fact it has a subwoofer (never heard another laptop sound like this model.....)
              But if things go on like this, i'll HAVE TO start thinking about another laptop, obviously with an NVIDIA card.

              At work i use another desktop pc, with an integrated video card. At home, i have an ancient desktop pc with a Celeron, and an old Nvidia card.
              They work, for what i've seen, wonderfully. Never a problem, like these shitty problems i have since when i bought this laptop with the Ati X1400 card.


              So, in the end: i'll watch this website only for solutions or reviews on the new releases of Ati drivers, but, I HOPE, only for little time.
              For me: Ati no more. Never.

                I am getting a lot of graphics corruption with this version. The screen will fill up randomly with the circular scroll icon when using middle click in Firefox. This started happening in 8.5.
                Now I am also getting that doubled screen mess that some one posted a picture of earlier.

                  Have you tried the xf86-video-ati driver? It might already be a viable replacement for fglrx with your GPU. I suspect there's still some kinks/quirks (3d support is still initial on r500 I believe), but at this rate it shouldn't be long before either (or both) the ati or radeonhd drivers will be far more usable than fglrx for you.

                  If you buy a new laptop with an Nvidia GPU, by this time next year you'll be so jealous of all the people happily running the open drivers while you have to deal with Nvidia's bugs (which from my experience probably won't be as horrible as ATI's, and won't keep you from using your computer, but they'll be irritating nonetheless, and the irritation will just keep growing because they'll never go away).

                  Appologies if I have failed to notice an eariler post of yours where you say the open driver(s) don't work for you. If I have missed such a post, then if my post so far hasn't made this obvious, I think you should hang in there a bit longer.

                    Problems:
                    1.Horizontal visual tearing when playing videos-->the card spews frames faster than the monitor/TV can finnish displaying.
                    2.The fan is constantly on and I am forced to use the special version of radeontool.

                    I have huge tearing when playing videos as well on my hd4850

                      Don't you worry, next driver release will have improved video playback

                        For those of you experiencing screen corruption/splitting:

                        Check what resolution the corrupt application is launching. I had this issue with mythtv (fullscreen or windowed) on my X1400 driven 1680x1050 laptop screen. By forcing mythtv to 1680x1024 or 1680x1080 the corruption cleared up! This is again some wacky thing about the 1050 lines resolution.

                        And I registered to bring you this... ain't I nice ;-)

                        This is a dup. of what I posted in another thread, but people may not be watching both, and this seems to be being seen by people in both threads.

                          yes but I can't use previous drivers because hd4850 isn't supported on them, again the best solution is to plug back a nvidia 6600GT.
                          I don't see how phoronix can claim that hd4850 are supported immediately by amd on linux while the only driver is badly broken, and can't even display properly a video, movies are unwatchable, that is a huge regression, at least for me coming from a 6600GT

                          so the 8450 and 8470 will be available, and we will just have many users saying "it doesn't work, as usual on linux"

                          I don't see how it's possible to pull out such bugs in the drivers.
                          I mean the black borders bug itself, or huge tearing in video, how can a developper not test that ?

                            Xv crashing with 8-6

                            I use mobility x1600 with 32-bit ubuntu hardy.
                            In about 50% of the sessions, attempting to use Xv crashes the hosting app (restarting X does not help) or the entire Xorg process (throwing me to command line while Xorg is stuck, un-killable, on 100% cpu). This happens with or without compiz. It never happened with the former driver. On the other 50% of the sessions Xv works fine.

                            Here, for example, is the output of vlc trying to play Xv file:

                            [00000295] a52 decoder: A/52 channels:6 samplerate:48000 bitrate:448000

                            libGL error: reverting to (slow) indirect rendering
                            X Error of failed request: BadMatch (invalid parameter attributes)
                            Major opcode of failed request: 163 (GLX)

                            Is there a solution for this? If there is not, how can I help debugging it further?

                              Mirak, are you still seeing the black borders or did the aticonfig commands get rid of them ? My understanding is that with HDMI TVs we set an 8% underscan by default since so many TVs are set to overscan (zoom in) and this is the only way to ensure that the user can find important things like menus.

                              re: the tearing, can you pls try to post a screen snap ? We have not seen this in our testing AFAIK.

                                hi,
                                about underscan it's ok that's it the default, like in windows drivers, however here the settings are not kept, so if I change the resolution or just reboot the computer the settings are lost, so I created a script that I run manually, but well I shouldn't have, like in windows.

                                about tearing there is a big tear at the 2/3 bottom of the screen, I don't know if a screenshot can take that since it's overlay, I will try later.
                                I have a P5Q pro with a Q9300

                                I have seen a topic here where people complain about tearing on 8.5 and 8.6 not only with hd4850
