    How do I enable direct rendering?

    I'm using an ATi Radeon X1100, and have installed Compiz Fusion... but it wont run without direct rendering, and I don't know how to turn it on.

    Re: How do I enable direct rendering?

    I'm not sure if it's possible. In my case, fglrx (the driver) is needed for direct rendering, but doesn't support compositing. Compiz/Beryl requires compositing. The open-source driver supports compositing, but it doesn't support my card.

    Let's see if yours does the same thing. Post (or, preferably, attach) /etc/X11/xorg.conf.

      I know someone else at ubuntuforums got Compiz to run on an X1100, but I've gotten no help there.

        Re: How do I enable direct rendering?

        Umm... You've turned off AIGLX near the top, but lower, in ServerLayout, you've turned it on.

        At the bottom, you have
        Section "Extensions"
        Option "Composite" "Enable"
        Option "Composite" "0"
        EndSection
        ...not sure what's up with that. But, if it works, don't change it. (I just had a round of that myself...) I'm guessing that the later one takes precedence.

        So, for Compiz, you'll need to turn on compositing. Remove the line turning it off. Now, this will also disable DRI (direct rendering infrastructure?), so we can't use fglrx. Go to the driver line (line 99) and change it to "radeon". Reboot. If you get a black screen, switch to a terminal (Ctrl+Alt+F1...F6) and execute "grep WW /var/log/Xorg.0.log && grep EE /var/log/Xorg.0.log". If it talks about an unsupported board, you're out of luck. I don't think you can use Compiz.

        However, if it starts up normally, open up Konsole and execute "glxinfo | grep direct". If it says "yes", go enjoy your wobbly windows. If it says "no" and mentions Mesa, do the "grep WW..." I mentioned above.

          Ok, it booted fine, but I got this:

          Code:

              Sorry. I don't usually get a chance to use my computer on Sundays.

              Anyway, I don't know if it's taking effect, but I think it is: line 147, AIGLX is explicitly enabled. Take that line out completely (or just comment it out).
              Option "AIGLX" "true"

                Hmm, no change yet... is there any kind of command line to force direct rendering on.

                  Fglrx and AIGLX

                  fglrx doesn't support AIGLX. Maybe someday:
                  http://www.phoronix.com/scan.php?pag...item=782&num=1
                  Moving forward to the 8.39.4 driver released today, we still have no AIGLX or R600 support
                  If you want Compiz Fusion/( Beryl) use:

                  a) AIGLX (using open source ATI driver)

                  b) XGL (using closed-source ATI driver = fglrx)

                  After you have installed AMD(Ati) drivers

                  From Ubuntu Feisty Installation Guide
                  http://wiki.cchtml.com/index.php/Ubu...allation_Guide
                  Disable Composite Extension

                  In Ubuntu Feisty the Composite extension is enabled by default, however, fglrx does not yet support Composite with DRI. In order to disable Composite you have to edit the xorg.conf file:

                  and add these lines at the end of the file:
                  File: /etc/X11/xorg.conf

                  Section "Extensions"
                  Option "Composite" "Disable"
                  EndSection

                  Section "ServerFlags"
                  Option "AIGLX" "off"
                  EndSection
                  And remove other composite/AIGLX markings.


                  is there any kind of command line to force direct rendering on.
                  Well - There is something wrong in the xorg.conf (or your computer thinks so). That is the reason why direct rendering:
                  (WW) RADEON(0): Direct rendering disabled

                  How did you install fglrx ?

                    Do you have a file with all these things all typed out to copy-paste into a post, or what?

                    Anyway, you now have the radeon driver, compositing on, and AIGLX off, correct? Hmm. Try turning AIGLX on.

                    At this point, it's mostly "well, try turning this on, and if that doesn't work, try turning this on...".
