I think you have to change /etc/hosts also, so if you open a terminal and type
gksu gedit /etc/hostname
edit it, save and exit.  Then
gksu gedit /etc/hosts
and edit a line which should be something like
127.0.1.1      your_current_host_name
replacing the current name with the desired new one (leave the rest of
the file as it is), then save exit and reboot and I believe that
should do it.  It might be best to hang on a bit however in case
someone else comes up with more things you need to do.
