[ltp] logitech cordless desktop optical, special keys not working

[Matthias Himber]

Well, there has been some demand, so here is the stuff. I cannot guarantee 
this works on any System other than mine (SuSE Linux, using X.org X11R6.7).

First, find the xkb base directory. On my SuSE System its /etc/X11/xkb, but on 
your System it might be different. Here is what it looks like:

Now, edit the file symbols/inet, adding the following:

partial alphanumeric_keys
xkb_symbols "ltcdmx" {
    name[Group1]= "Logitech Cordless Desktop MX";

    // Left side
    key <I16>   {       [ XF86WheelButton       ]       };
    key <I6A>   {       [ XF86Back              ]       };
    key <I69>   {       [ XF86Go                ]       };

    // Top left
    key <I5F>   {       [ XF86Standby           ]       };
    key <I6C>   {       [ XF86Mail              ]       };
    key <I11>   {       [ XF86Messenger         ]       };
    key <I12>   {       [ XF86WebCam            ]       };

    // Top center
    key <I10>   {       [ XF86AudioPrev         ]       };
    key <I19>   {       [ XF86AudioNext         ]       };
    key <I6D>   {       [ XF86AudioMedia        ]       };
    key <I2E>   {       [ XF86AudioLowerVolume  ]       };
    key <I30>   {       [ XF86AudioRaiseVolume  ]       };
    key <I20>   {       [ XF86AudioMute         ]       };
    key <I22>   {       [ XF86AudioPlay, XF86AudioPause ] };
    key <I24>   {       [ XF86AudioStop         ]       };

    // Top right
    key <I13>   {       [ XF86iTouch            ]       };
    key <I65>   {       [ XF86Search            ]       };
    key <I32>   {       [ XF86HomePage          ]       };
    key <I14>   {       [ XF86Shop              ]       };
    key <I66>   {       [ XF86Favorites         ]       };

    // Extended Fn keys
    key <I3B>   {       [ XF86New               ]       };      // F1
    key <I3C>   {       [ XF86Reply             ]       };      // F2
    key <FK13>  {       [ XF86MailForward       ]       };      // F3
    key <FK14>  {       [ XF86Send              ]       };      // F4
    key <FK15>  {       [ Undo                  ]       };      // F5
    key <FK16>  {       [ Redo                  ]       };      // F6
    key <FK17>  {       [ Print                 ]       };      // F7
    key <I42>   {       [ XF86Save              ]       };      // F8
    key <I43>   {       [ XF86MyComputer        ]       };      // F9
    key <I44>   {       [ XF86Documents         ]       };      // F10
    key <I57>   {       [ XF86Pictures          ]       };      // F11
    key <I58>   {       [ XF86Music             ]       };      // F12
};

Now, in the file rules/xfree86, look for the long list of Internet Keyboards, 
it looks like this:

! $inetkbds = airkey acpi scorpius [...more...] trust trustda yahoo

Add "ltcdmx" in there somewhere.

Now, if you want to use some graphical configuration Tool to tell XFree to 
load the keymap, you will have to edit rules/xfree86.lst and 
rules/xfree86.xml, but these files should be self-documenting. To do it 
manually, open the XF86Config in your favorite editor and in the appropiate 
InputDevice section for your keyboard put the line

Option "XkbModel" "ltcdmx"

remove any existing 'Option "XkbModel"' line, of course.

If this, please tell me as I would then try to submit it to X.org.

Have a lot of fun,
	Matthias
