Media keys no longer assignable in eos7

[svandragt]

What Happened?

In eos6.1 I was able to set my eject key to trigger multitasking view but on eos7 the key is no longer recognised when attempting to capture it (setting a new shortcut key). Instead nothing happens.

Steps to Reproduce

1. Open Keyboard settings > Shortcuts > Workspaces
2. Click the cog on Multitasking View > Set New shortcut
3. Press the eject key

Expected Behavior

Eject key is set as shortcut

OS Version

7.x (Early Access)

Software Version

Latest release (I have run all updates)

Log Output

This is the log of xev for a keypress and release of the eject key:

I tried the same way with #457 to fix this issue and confirmed I can assign Eject key for shortcuts on my MacBook Air (11-inch, 2010):

However, the assigned action is not triggered for some reason even if I push Eject key. (might be swallowed by someone like GSD?)

[svandragt]

As a workaround you can use dconf and set the <Eject> string as a value for the keybinding (in my case /org/pantheon/desktop/gala/keybindings/expose-windows) until the settings panel is updated. Interestingly, for me that is triggering once it is assigned.

However, the assigned action is not triggered for some reason even if I push Eject key. (might be swallowed by someone like GSD?)

Kind of... When gala starts, GSD grabs all media-keys listed as *-static in /org/gnome/settings-daemon/plugins/media-keys/ (such as XF86Eject or XF86AudioLowerVolume) and for that reason the shortcuts are not triggered.

The workaround is to find corresponding *-static shortcut in /org/gnome/settings-daemon/plugins/media-keys/ and remove it. After that the <Eject> (and all the others) should work.

TBH I don't know why *-static exists. Maybe we can move the *-static shortcuts into their normal versions and fix the issue by displaying the shortcuts in the plug.
