I am trying to apply this fix for 13.10 Xubuntu
For those looking for a temporary workaround, look at /usr/share/dbus-1/services/indicator-sound.service and change the Exec line
But I can't edit the file without root access? How do I get root access? I know there is way to do it via a gui with mouse pad or leafpad, but when I type gksudo is says it's not found. Do I install it? What commands do I use?
