Asus G74SX-DH71 Keyboard lights Function Keys in KDE (Debian and Fedora)

I was trying for a while to make my Function Keys (volume, keyboard lights, etc) work in KDE 4.x, and I was finely able to do it with a *funny* workaround. It turns out that the Fn keys works just fine in Gnome, so I dig a little bit and found that the responsible of making this work is a small daemon called gnome-settings-daemon… So it’s just a matter of starting up this daemon in KDE and that’s it.

So, for doing that I just needed to add the next bash file:

$vi ~/.kde/Autostart/gnome-settings-daemon.sh

and add this line:

For Debian:

gnome-settings-daemon

For Fedora:

/usr/libexec/gnome-settings-daemon

we save the file and then add exec permissions

$chmod u+x ~/.kde/Autostart/gnome-settings-daemon.sh

Now you need to logout and login again and that’s it.

For getting the screen brightness function keys working properly, we need to edit our xorg.conf file:

#vi /etc/X11/xorg.conf

Under the section “Device” we need to add:

Option "RegistryDwords" "EnableBrightnessControl=1"

So, at the end, our “Device” section should look similar to:

Section "Device"                                                                                                                     
    Identifier  "Video Card"                                                                                                         
    Driver      "nvidia"                                                                                                             
    Option "RegistryDwords" "EnableBrightnessControl=1"                                                                              
EndSection

You need to reboot in order to get this working.

Hope that works for you. 🙂
