Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

In short: is there (under Unity) any way to find out which application grabbed some global shortcut? I do not ask for "standard shortcuts" but for some way to get information about actual shortcuts (which app is actually keeping given key just now in my current config)

Longer story:

I have repeatable problems with managing keyboard shortcuts. At the moment:

  • Synapse sometimes (*) can't bind Win-Space as it's activation shortcut, reporting "Failed to register hotkey 'activate' with signature 'space'" (what usually means that this shortcut is already taken)

    (*) After one login it works, after another login it does not. I suspect some race between two apps…

  • F9 for some reason makes my screen slightly darker (and F9 does not reach application-level shortcuts so for example my byobu menu does not work)

I tried looking at various places, and:

  • I do not see any of those shortcuts in Keyboard settings/Shortcuts

  • I can't find them in gconf-editor (I tried searching for F9 in values in particular, nothing found)

  • I could not find them in dconf-editor (there is no search so I clicked some most obvious paths)

So my question is: is there any way to ask unity/dconf/gconf/d-bus/whatever about current global hotkeys allocation (which process is keeping which key). Or force logging those allocations to some log file. Or grep them from somewhere. Or………

Could you clarify or define (for the purpose of this question) what is meant by global shortcut? –  user25656 Mar 7 '13 at 17:06
The key which I press and which causes something unrelated to the currently active window to happen. For example global shortcut Win-S opens expo view, global shortcut Alt-Tab switches windows, F12 (in my setup) opens tilda drop-down terminal etc etc. And, as I said, whenever I press F9, the screen dims, and I have no clue which app does that and why. And something sometimes grabs Win-space. And in the past I happened to see F12 taken away from tilda (luckily this problem went away). So I'd be happy to have some way to examine those keyboard allocations. –  Mekk Mar 7 '13 at 17:33
