Are KC_MEDIA_EJECT & KC_MEDIA_SELECT correct?

[DidierLoiseau]

Currently trying to reproduce the TypeMatrix 2030 on my ErgoDox EZ.

fn+F6 on the TM is mapped to "eject". I tried to use the KC_MEDIA_EJECT for this but it does not seem to send the correct keycode. I am working on Ubuntu, here is the output of xev with those keys:

TM 2030:

KeyPress event, serial 53, synthetic NO, window 0x5200001,
    root 0xd9, subw 0x0, time 191628480, (142,442), root:(363,710),
    state 0x10, keycode 169 (keysym 0x1008ff2c, XF86Eject), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 53, synthetic NO, window 0x5200001,
    root 0xd9, subw 0x0, time 191628552, (142,442), root:(363,710),
    state 0x10, keycode 169 (keysym 0x1008ff2c, XF86Eject), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

(note that this works with the default Gnome3 keyboard shortcut – it ejects the CD tray)

ErgoDox EZ:

KeyPress event, serial 55, synthetic NO, window 0x5200001,
    root 0xd9, subw 0x0, time 191723071, (585,221), root:(806,489),
    state 0x10, keycode 248 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 55, synthetic NO, window 0x5200001,
    root 0xd9, subw 0x0, time 191723142, (585,221), root:(806,489),
    state 0x10, keycode 248 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

Also, I was curious about what was KC_MEDIA_SELECT so I added it to my keymap. Here is what it gives:

KeyPress event, serial 83, synthetic NO, window 0x5200001,
    root 0xd9, subw 0x0, time 191864282, (301,-52), root:(522,216),
    state 0x10, keycode 179 (keysym 0x1008ff81, XF86Tools), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 83, synthetic NO, window 0x5200001,
    root 0xd9, subw 0x0, time 191864354, (301,-52), root:(522,216),
    state 0x10, keycode 179 (keysym 0x1008ff81, XF86Tools), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

So Ubuntu recognises it as a "Tools" key. In fact, the default action on Gnome3 for this key is to open the Gnome Settings.

It looks like this is a known issue with the eject key - that's all the info I have on it right now :/

Thanks, this is actually discussed in tmk/tmk_keyboard#250

I tried to use F20 as suggested but that does not work: it sends the AudioMicMute. Gnome3 even recognises and apparently mutes the microphone, but I cannot find where this is configured. Anyway I think this is Linux-specific as Freedesktop remapped a Mac Mic-Mute to F20: https://bugs.freedesktop.org/show_bug.cgi?id=54171
