I try to dim the display for my iBook G4 (late 2004) during startup. For that reason I've added LCD_Brightness=0 to pbbuttonsd.cnf. The display is dark after bootup. The brightness can be adjusted as usual using keyboard. With this setting in place, I'm not able to stop the daemon using rc script. plex ~ # cat /etc/pbbuttonsd.cnf # Configuration file for pbbuttonsd >= version 0.8.0 # For complete list of options please see pbbuttonsd.cnf man-page. # For description of the file format please see # http://freedesktop.org/Standards/desktop-entry-spec.

It seems that the root cause of this issue is related to mypiece of Apple hardware. I've double tested and it seems that the daemon is not the culprit here. I've noticed a situation where my iBook is restarted and the display is flipping trough different colors during boot time. (red, blue, yellow, white...) A remote log on is possible and the operating system is working fine but the console is not reachable. In that situation the daemon "hangs" and pulls a lot of cpu power. Have someone seen similar issues with Apple hardware and framebuffer? The notebook must be fully powered off and restarted to resolv that issue.
