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?
Thanks!!
It would appear that the root cause of this problem is the service HAL: somehow, this service isn't started most of the time on my machine. To start, use:
sudo hald --daemon=yes
To configure the keys used for volume up, and volume down, press ALT+F2, type in gconf-editor, and press Enter. Then, navigate to /apps/gnome_settings_daemon/keybindings.
The values on my system are:
volume_down -> XF86LowerVolume
volume_up -> XF86RaiseVolume
volume_mute -> XF86Mute
If those don't work for you you can use xev to figure out the exact keycode your media keys fire and configure those.
