https://apps.ubuntu.com/cat/applications/quantal/gnome-system-monitor/
It comes already installed with Ubuntu (I think).

-h does not seem to be a valid option for free, but without that option
               total           used          free       shared

No it is not swapping, but I had expected it to show that there is
swap space available.  Perhaps it is fine and swap space will be made
available if it is needed, I don't know.  Is there a simple way of
using up lots of ram so to force it to swap?
