Red Hat Bugzilla – Bug 224564
Brightness keys don't adjust LCD brightness on PowerBook G4
Last modified: 2013-03-05 22:48:51 EST
Description of problem: Version-Release number of selected component (if applicable): gnome-power-manager-2.16.0-4.fc6 (assuming, of course, that it's gnome-power-manager that's responsible for this -- I'm not sure if it is or not) How reproducible: Always Steps to Reproduce: 1. Press the Brightness keys (F1 and F2) 2. Watch the Gnome on-screen display pop on the screen, and see it act like it's changing the LCD brightness 3. Notice that the LCD brightness doesn't change at all. Actual results: Nothing happens Expected results: The LCD brightness should go up or down, as appropriate. Additional info: I can manually change the LCD brightness by typing: echo -n '127' > /sys/class/backlight/*/brightness (where you obviously change 127 if you want it darker or brighter)
I don't know if this should be filed as a seperate bug or not, but the keyboard backlight doesn't work at all, either. (I'm happy to file it as a seperate bug -- just let me know.) I can get the keyboard backlight to work if I install the pbbuttonsd application, but it's not part of Fedora Core or Fedora Extras.
You need to use CVS HAL for the /sys/class/backlight stuff to work. There are rpm's in the utopia repository if you are interested.
I'd be happy to try the RPMs from the utopia repo, if I could find them. Google doesn't seem to be able to find the repo for me. Can you please point me to the repo?

There wasn't a HAL RPM for PPC in the utopia repo, so I took the SRPM and rebuild it. Only one problem, it requires hal-info, which I can't seem to find anywhere.
OOps. Sorry, should be there now: http://people.freedesktop.org/~hughsient/fedora/6/SRPMS/
This is working in FC7, so I'm going to go ahead and close this bug.
