Re: xserver, video playback, direct rendering etc.
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

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 fashion.
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.

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.
