Description Robert Schuster 2008-07-31 09:56:49 UTC
Description of problem:
I have a white ibook G4 running Fedora 9 (upgraded from F8). In order to adjust
LCD brightness, sound volume, sound muting one should normally press the fn key
in the lower left corner and one of the function keys (fn + F1 to lower the

The problem is that it looks like the fn key is in pressed state always. This
means I can adjust brightness by just pressing F1 or F2. If I want the normal
behavior of a function key (e.g. opening the GNOME help) I need to press fn plus
a function key. So the mechanic is actually reversed. This is pretty annoying
when wanting to switch to the (non X11) console.

The odd behavior of the fn key is also apparent at the raw linux terminal which
is why I think this is a kernel issue.

Version-Release number of selected component (if applicable):
(I had this problem with all of the kernel available for F9. It was not there on

How reproducible:

Steps to Reproduce:
1. Power on laptop, logon to X11.
2. Press F1 - if it dims the LCD backlight, this is the problem
Actual results:
Pressing F1 dims LCD backlight.

Expected results:
Should open the GNOME help.

Is this fixed in

Comment 3 Robert Schuster 2008-10-24 09:20:19 UTC
I updated to kernel and the problem is still there.

A friend told me that MacOS X has an option to reverse the behavior of the fn key.
I assume if such an option exist it would be stored in nvram. I searched the 'common' partition for a suitable entry but found none.

Since I have never used OS X on this machine (except for burning the Fedora CD) I also have doubts that this could be the reason for this issue.

Is there anything I could do to better identify the problem? Setting kernel log level, output of some /proc or /sys files or something like that?

Comment 4 Robert Schuster 2008-11-20 22:41:04 UTC
I upgraded to the latest kernel on Fedora 9 and the problem is still there.

I wonder whether I am the only one experiencing this problem... :$

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 

Comment 6 Bug Zapper 2009-07-14 15:53:17 UTC
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
