Default Problems with ancient ATI graphics card

Hi,

this is a bit off topic, since it primarily concerns a laptop running
OpenSuSe 11.3, but I do need your help and I known there are experts
here.

This old laptop has a
radeon RV350 (mobility Radeon 9600 M10) graphics card.

There is an xf86-video-ati driver installed.

Now, when booting with the (default) radeon.modeset=1
the graphics is dead slow (not only for glxgears : 200 frame/s but for
my OpenGL application (Impressive), as well).

Now, when I replace the option on the kernel command line to
radeon.modeset=0
glxgears is much faster ( about 1800 frames/s )
BUT my OpenGL application (python gtk + opengl)
now freezes the whole machine - only power on/off can revive
it.

Hopefully, someone has an idea on what is going wrong here.

(The hardware is too old for a recent ATI closed source driver
supporting a recent kernel 2.6.34.x)

Many thanks for your help which is very much appreciated.
Helmut.

I have a very similar card in my Gentoo laptop (Mobility Radeon 9700,
I think maybe it's the same as 9600 but clocked higher). I tried KMS
radeon driver but had some issues, maybe it was user-error but when I
disabled KMS everything went back to normal.

Otherwise if you want to stick with KMS all I can think of is to try
different AccelMethod settings in your xorg.conf to see if you get
better performance from one of them. I think maybe you need to disable
console framebuffer as well, in case you're using one.

Hi Paul,

it turned out there is a bug in the linux kernel up to and including
2.6.36 concerning
drivers/gpu/drm/radeon
when it comes to all graphics chips like RV350.

Does anybody know about a patch for gentoo-sources-2.6.36 ?

Many thanks for a hint,
Helmut.

Hi all,

I have an old RV350 9600 ATI graphic card and the open source radeon
driver works fine with 2.6.36 kernel.

Cheers,

That depends on the application. e.g. glxgears runs fine while a
PyOpenGL application crashes the whole machine.

See
https://bugs.freedesktop.org/show_bug.cgi?id=28402

You might try
http://impressive.sourceforge.net/

(it needs PIL, PyGames and PyOpenGL)
