Re: xserver, video playback, direct rendering etc.

Output of fglrxinfo:

Hmmm... that may be the problem...

Sorry, no, xlibmesa-dri has been replaced by libgl1-mesa-dri which is
installed (the latest version).

    Thanks for the suggestions, Kelly.

    First I stuck with the fglrx driver and added the two options to the
    "Device" section of xorg.conf.  Unfortunately this didn't seem to
    make any difference to the video playback; i.e., it's still stuttering.

    Then I tried both the RadeonHD and the Radeon drivers.  The xserver
    starts in each case (as expected) but direct rendering is disabled.
     Is there anything I can do to enable direct rendering with either
    of these drivers?

            Dear Debian users,

            I installed lenny on a new system last week.  Without
            changing anything,
            the xserver started successfully.  (Thanks!)  But direct
            rendering was
            disabled.  (No surprise there.)  Regardless DVD/video
            playback was
            satisfactory using totem-xine.  However it was desirable to
            try to get
            direct rendering working for all sorts of reasons so I:

            1. installed fglrx-driver and fglrx-kernel-src
            2. used module-assistant to build and install the fglrx module
            3. used aticonfig to update xorg.conf

            When I restarted the xserver, direct rendering was indeed
            enabled but
            DVD/video playback now "stutters" every minute or so.  Also,
            when my kids
            play "Extreme Tux Racer" the video stutters in a similar

            The other problem I have, regardless of the video driver, is
            that the
            xserver crashes in certain situations:
            1. switching users via the User switcher applet; or
            2. if the screensaver puts the display to sleep

            By "crash" I mean no video and no keyboard so must reboot.

            My kernel is:
            Linux mozart 2.6.26-1-686 #1 SMP Thu Aug 28 12:00:54 UTC
            2008 i686

            and I have included my xorg.conf and lspci info below.

            I'd be grateful for any help or suggestions.


            01:00.0 VGA compatible controller: ATI Technologies Inc
            Radeon HD 2400 XT

        That is an r600 series, if all else fails, you might get
        somewhere with the
        Radeon driver or the RadeonHD driver

        I don't think your problem has much to do with your xorg.conf,
        but it is
        really old and should be cleaned up anyway.

        The comment block at the  top is old and all wrong and could be
        removed to
        prevent confusion. The "Files" and "Modules" sections are no
        longer needed,
        and can be removed.

        This part *might* actually be relevant to your issue:
        In the "Device" section, try putting:
        Option          "RenderAccel"      "true"
        Option          "DRI"                   "true"

        I am not sure about this, as fglrx does things very differently
        from the OSS

        Sorry I can't offer more help.
