    Help! - Window Translucency and Shadows

    Hi Everyone,

    I really like the look of the translucent windows and shadows. When right clicking on the window and enabling the translucency, nothing happens. When I log out, I get this error:

    "Composite extension not found
    You must use XOrg ≥ 6.8 for translucency and shadows to work.
    Additionally, you need to add a new section to your X config file:
    Section "Extensions"
    Option "Composite" "Enable"
    EndSection"

    I have added

    Section "Extensions"
    Option "Composite" "Enable"
    EndSection"

    to my xorg. When I do, and restart the x server, Kubuntu doesn't even load. I'm stuck at the loading screen, and I cannot een get to the login screen. I manually remove the code, and it works fine. I would like to enable this, but I don't know how.

    Any help would be great,

    Mr_Welfare

    Note: I'm not sure what version of Xorg I am using. I am running Dapper.

    I've looked for howtos on this as well. They all say that you have to update your XOrg to higher than 6.8. How do I tell what version I am running, and how do I update it if needed?

    Oh and one thing I forgot to mention.

    I placed this code:

    Section "Extensions"
    Option "Composite" "Enable"
    EndSection"

    to sudo nano /etc/X11/xorg.conf. (I hope that is the right spot)

    Even when I added it, like I said before, the OS itself won't boot.

      Whichever you use ATI or Nvidia have you installed those drivers ? Ubuntu is up to Xorg 7.1, which enables compositing for xgl on ATI cards (currently Nvidia driver doesn't support compositing).

      Install your driver and you should be fine. Here is a good source of info.

        I am using an Nvidia card. I followed the instructions in the link that you posted, and after installing the package and enabling it through the terminal, I logged out and restarted my Xserver (Control Alt Backspace)

        After doing this, my Kubuntu wouldn't boot (much the same as if I added the line of code to it manually).

        I had to reconfigure my xerver using

        sudo dpkg-reconfigure -phigh xserver-xorg

        for it to work again.

        Any other suggestions?

        Thanks,

        Mr_Welfare

          I've had this working with an nVidia card before (then I went to a dual-monitor setup, which kind of broke things).
          Section "Extensions"
          Option "Composite" "Enable"
          EndSection"
          Is that final end-quote (") a typo or is it really in your /etc/X11/xorg.conf file? If it is, try getting rid of it and see if that helps.

          If not, then try starting X from a console (by typing startx) and see if that gives any error messages.

            When I add the code to my xorg.conf, this is what I get for an output. (I tried removing the ("), but the error message still stayed the same.)

            xauth:  creating new authority file /root/.serverauth.11209
            xauth:  creating new authority file /root/.Xauthority
            xauth:  creating new authority file /root/.Xauthority

            Fatal server error:
            Server is already active for display 0
                    If this server is no longer running, remove /tmp/.X0-lock
                    and start again.

            Any suggestions on how to fix this?

            Thanks,

            Mr_Welfare

            EDIT: I seem to get this error even with a xorg.conf that works. Also, are you sure this works with an Nvidia card?

              Ok it's now working. Thanks a bunch for your help!

              A note to anyone else: The extra (") messes it up. DELETE IT!

              Also, is there any way to reduce the lag that hits your computer when you turn on the transparency? My computer is not short on processing power (graphical or CPU) and it's not short on memory either. Is this just a bug that hasn't been worked out yet?

                I believe you can tweak the fade in fade out speeds in the effects tab in the translucency part of the Window behaviours section, the sliders adjust the speed, etc.
