Is it possible to reopen this bug??
Please file a new one, as it's fixed for other people. Do the

I don't understand why we have to rely on 3rd party packages to fix

No, I think it can be solved. I mean it will be a fix (or a hack)

Martin, which packages/repositories will the backports be found in?
Also, out of curiosity: voria/ppa solution relies on xbindkeys, which
