I recently upgrade to Ubuntu 10.10 Maverick Meerkat and to my dismay, the mediakeys "volume up" and "volume down" do not send Dbus signals anymore... how can I add these back?


Update: it seems that under some circumstances (which I don't know exactly yet), the DBus signals start working again. It is as though when a certain application (TBD) is executed, the dbus signals are re-activated.

Found the problem: the service HAL isn't running. To start, use:

sudo hald --daemon=yes


Try opening Keyboard Shortcuts (System -> Preferences -> Keyboard Shortcuts or Alt-F2 gnome-keybinding-properties) and reassigning the Volume Up and Volume Down keys.
