output from "dmesg|grep -e drm -e radeon"

Hello!

I am using Ubuntu 10.04 on my G4 Mac mini, Radeon 9200 32MB.

Disabling the kms (radeon.modeset=0) with the forums help, it was possible to fix a compatibility problem between radeonfb and the kms drm. In glxgears the fps increased to over 800, with some xorg.conf modifications even to 1300.

Following I recognized that in several applications the 3d-acceleration was now present but broken.
- Visual effects for gnome session -> blue coloration, windows remain visually after being closed
- Tuxkart -> blue coloration, sound and graphic stutter
- Warsow -> blue coloration, sound and graphic stutter

Thank you for your help!

dmesg shows:
radeonfb 0000:00:10.0: Invalid ROM contents

In the xorg.log line 744:
(II) RADEON(0): Render acceleration disabled

If you enable KMS but disable radeonfb instead, does that work any better?

These are probably 3D driver issues, reassigning.

I enabled KMS and disabled radeonfb. In KMS's default modeset, the system crashes during the boot process.

With radeon.agpmode=4 the system boots fine. 3d acceleration is enabled but works only with some application and is really slow. -> regular system crashes

Forcing the PCI mode with radeon.modeset=-1 the system boots fine.
3d acceleration is enabled and works (no blue tins or flickering), but is really slow: When Visual effects for gnome session are enabled, glxgears gives 20 fps, without visual effects: 400 fps.
Tuxkart or Flightgear are not usable.
