Version-Release number of selected component (if applicable):
Steps to Reproduce:

The same here with Laptop Fujitsu Lifebook E8420.
The FN-Keys don't change the backlight. The symbol occurs on the screen, but the backlight doesn't change the brightness. In gnome-shell the slider in the upper right menu works fine.

This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. Approximately 4 (four) weeks from now this bug will

of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
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.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 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no longer maintained, which means that it will not receive any further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.

Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
