Description Jared Smith 2007-01-26 09:41:47 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:


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.
Comment 3 Jared Smith 2007-01-26 15:44:36 EST
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
Comment 5 Jared Smith 2007-01-29 17:29:06 EST
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

OOps. Sorry, should be there now:

This is working in FC7, so I'm going to go ahead and close this bug.
