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. Nobody, Ubuntu 10.04 Desktop reached EOL on May 9, 2013. For more on this, please see https://wiki.ubuntu.com/Releases . If this is reproducible in a supported release, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal: ubuntu-bug xorg Also, please feel free to subscribe me to it.

Created attachment 42983 [details] 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!
