Comment 3 for bug 267018

As near as I can tell, this is still present in jaunty.

/usr/share/gconf/schemas/apps_gnome_settings_daemon_keybindings.schemas contains:

        <schema>
            <key>/schemas/apps/gnome_settings_daemon/keybindings/xrandr</key>
            <applyto>/apps/gnome_settings_daemon/keybindings/xrandr</applyto>
            <type>string</type>
            <default>0xd6</default>
            <locale name="C">
                <short>Activate connected display</short>
                <long>Activate a connected display using xrandr</long>
            </locale>
        </schema>

If I disable my keybinding override (which had pointed this at XF86Display), then Fn+F7 has no effect. (If I re-enable my keybinding override, it has lots of broken effects, but that's for another bug report. :-)

I'm pretty sure that this is an event that belongs in the keyboard event layer (per https://wiki.ubuntu.com/Hotkeys/Architecture) rather than as a hal event; so this looks unfixed to me.
