   You can manage your Fn keys in different ways. How I did it:
   Go to your home folder using PCManFM file manager, press Ctrl+H to show hidden files and folders.
   Enter to folder .config (yes, name begins with dot), then enter to folder openbox, and open file rc.xml in text editor.
   Search for line:
   

   </keyboard>

   Copy next code and paste it above the line you found:
   

   <!-- my additional hot keys: START -->
       <keybind key="XF86AudioMute">
         <action name="Execute">
           <command>amixer set Master toggle</command>
         </action>
       </keybind>
       <keybind key="XF86AudioRaiseVolume">
         <action name="Execute">
           <command>amixer set Master 5%+</command>
         </action>
       </keybind>
       <keybind key="XF86AudioLowerVolume">
         <action name="Execute">
           <command>amixer set Master 5%-</command>
         </action>
       </keybind>
       <keybind key="XF86AudioPlay">
         <action name="Execute">
           <command>alsaplayer --pause</command>
         </action>
       </keybind>
       <keybind key="XF86AudioNext">
         <action name="Execute">
           <command>alsaplayer --next</command>
         </action>
       </keybind>
       <keybind key="XF86AudioPrev">
         <action name="Execute">
           <command>alsaplayer --prev</command>
         </action>
       </keybind>
       <keybind key="XF86Sleep">
         <action name="Execute">
           <command>sudo pm-suspend</command>
         </action>
       </keybind>
       <keybind key="A-Print">
         <action name="Execute">
           <command>mtpaint -s</command>
         </action>
       </keybind>
       <keybind key="XF86PowerOff">
         <action name="Execute">
           <command>poweroff</command>
         </action>
       </keybind>
       <!-- my additional hot keys: END -->

   Save the file and close text editor and PCManFM. Minimize all your opened applications, press right mouse button on free space on the desktop, select menu 'Openbox' and press 'Reconfigure'. Done.

   Now you can: mute, unmute, rise and lower volume, control alsaplayer, make screenshot (Alt+PrtScr), power off using Power button (though, Sleep button not work, but let the code be here).

   Note, that I have next button layout:
   Sleep: Fn+F4
   Mute/unmute: Fn+F8
   VolumeUp: Fn+Up
   VolumeDown: Fn+Down

   You can have your different layout, and everything should work as expected, because code above use names of keys, not layout.

   On my netbook it is done out of the box. Both brightness control and touchpad on/off. I think, these keys are hardware driven.

   I don't know properly, maybe xset helps you. Install package xorg-xset, type in terminal:
   

   xset --help

   Reading xset man page I see that it can't help you to control screen brightness. I found good article on the ArchWiki: https://wiki.archlinux.org/index.php/Backlight

   Read and try. By the way, xbacklight you can find in the xorg-xbacklight package, redshift in the redshift package (need python), setpci in pciutils. Xcalib, relight, calise are absent.

   Good luck! Post here results of your work.

   For me too. I have empty folder /sys/class/backlight, what about you?

   Even if I connect to the netbook an external monitor (TV, located in the kitchen), turn it on by LXrandr, then still nothing change.
