Not Working Yet

These are the niggles I haven't fixed yet... Always work in progress

    Mute does not work, even though it sends a pipe / bar character    |
    
    

Output codes

The remote shows up as a USB attached keyboard, and it can also send mouse events. You cannot change the keycodes that the remote sends, you can only change what your computer does when it receives the keystroke. Here's a full list of the keystrokes it sends. Please remember Keycodes aren't ascii or hex or anything, they're just numbers for your xserver to respond to.

Delete

I've listed which key is pressed as far as I can see, including if its the left or the right key. Mythtv makes no use of the windows key, so you can use "Desktop" to delete because win+D is treated the same as a D on its own.

Xmodmap content

  1. Just put this file in ~/.Xmodmap
    ! volume down
    keycode 122 = bracketleft
    
    ! volume up
    keycode 123 = bracketright
    
    ! Play/Pause
    keycode 172 = p
    
    ! Stop key
    keycode 164 = p
    
    ! Mute 
    keycode 160 = bar
    
    
    
  2. Then add a line to ~/.Xsession to call
    /usr/bin/xmodmap ~/.Xmodmap 
    
    which will load the modified keymap.

The Other Way

The other way to do this is to modify the key bindings in mythfrontend so that the key combo sent by the remote does what you expect. I have not persued this line.

The main drawback of this is that the frontend's regular keyboard would be affected, if you assigned a key to do something else.
