view story

http://ubuntuforums.org – I've been using Ubuntu 12.10 fore months now and all of a sudden today a log in and my Fn keys won't change the volume and i noticed there was no volume indicator from my top panel was gone so now can't change my volume unless I use the terminal. I've also tried launching gnome-sound-applet from terminal but to no avail: Code: ~$ gnome-sound-applet (gnome-sound-applet:5713): sound-cc-panel-WARNING **: Failed to connect context: Connection refused Any ideas?
