OpenGL renderer string: Mesa DRI R200 20060327 AGP 1x x86/MMX/SSE2 TCL

One thing I note is that I used the following version of Mesa DRI R200
in my experiments with the 9250: 20060602 (what comes with Debian Etch).


Here's something I probably should have mentioned earlier. I have Ubuntu
Edgy installed on this machine (triple boot XP/Mdrv2007/Ubuntu6.10. I
don't actually use Ubuntu, but I installed it to see what all the fuss
was about. I configured Beryl on it immediately after I installed it
and it runs much more smoothly. I don't have the same problems under
Ubuntu that I have under Mandriva.

Just wanted to get that out there. It seems to be a stinging indictment
of Mandriva, though the framerate I'm getting under Ubuntu is only about
698 fps.

Also, remember the problem I'm talking about here is NOT RELATED TO
BERYL. I'm seeing these slowdowns under KWin -- not just Beryl.

Now, I'd love to solve all this with a stick of RAM and/or a $150-ish video card, but I'm not sure how realistic that is -- nobody I've had this discussion with in Usenet or on the Mandriva support boards has any idea why rendering is so slow on this desktop.

The most likely culprits just seem to be the ATI drivers. What is your sense about that?

I also think it's a software problem, either the version you use, or
some configuration problem.


See above


Anyway, if the Mandriva people feel that they have problems with the
Radeon driver, maybe the Radeon driver distributed with Mandriva is
flawed. Or maybe the people there know as little what the problem is
as I do, and a few of those then point somewhere (whereas the wiser
ones shut up).

I agree.


One thing you could try is to see if the Knoppix 5.2 DVD works with
Beryl on your hardware (if you can get it; this version is not
available for download, and basically only available with c't 7/07:-().
Interestingly, <http://www.knopper.net/knoppix/knoppix52-en.html>
says:

I'm not finding that for download and frankly, I just don't think it
would tell me much in light of the info from Ubuntu above.

A Radeon 9250 sounds like an ideal card.


Craaaap. And the fact is I have another brand new 9250 in a box in the
closet. I'm half tempted to swap out these cards and see if it makes a
difference.

Thanks much Anton. Let me know if you think of anything else.
