    Lightbulb Workaround for Samsung series3 Volume/Brightness FN control buttons

    Hi all.

    So I have Samsung series 3 Laptop (NP350V5C) and it seems that keyboard Volume control buttons does not work at all on ubuntu 13.04 / 13.10 / 14.04.
    When I press Fn+VolumeUp or Fn+VolumeDown - volume goes to maximum or minimum, but I cant regulate it.

    Workaround:

    You need to edit file
    Code:
    /lib/udev/hwdb.d/60-keyboard.hwdb
    Find line in SAMSUNG section:

    Code:
    # Series 3
    keyboard:dmi:bvn*:bvr*:bd*:svn[sS][aA][mM][sS][uU][nN][gG]*:pn*300E[457]*:pvr*
    ...
    Add these lines just before # Series 3:

    Code:
    # Workaround for samsung 350V 
    keyboard:dmi:bvn*:bvr*:bd*:svn[sS][aA][mM][sS][uU][nN][gG]*:pn*350V*:pvr*
     KEYBOARD_KEY_ce=!calc                    # Fn+F1  launch control setting / Run calculator
     KEYBOARD_KEY_d5=!wlan                    # Fn+F12 WiFi On/Off
     KEYBOARD_KEY_89=!brightnessdown          # Fn+F2
     KEYBOARD_KEY_88=!brightnessup            # Fn+F3
     KEYBOARD_KEY_82=!switchvideomode         #Fn+F4
     KEYBOARD_KEY_f7=!f22                     # Unknown (mouse trackpad / PrtSc / ...)
     KEYBOARD_KEY_f9=!f23                     # Unknown (mouse trackpad / PrtSc / ...)
     KEYBOARD_KEY_a0=!mute                    # Fn+F6
     KEYBOARD_KEY_ae=!volumedown              # Fn+F7
     KEYBOARD_KEY_b0=!volumeup                # Fn+F8
     KEYBOARD_KEY_b3=!prog3                   # Unknown (mouse trackpad / PrtSc / ...)
    
    # Series 3
    keyboard:dmi:bvn*:bvr*:bd*:svn[sS][aA][mM][sS][uU][nN][gG]*:pn*300E[457]*:pvr*
    ...

    Save the file and run this command from terminal as root:

    Code:
    # dpkg-reconfigure udev
    Restart computer.

    This workaround will work until next 60-keyboard.hwdb update.


    You're welcome!
