no copy/paste between vncviewer and shell

In case that there is no copy/paste functionality between a vnc session and
your linux shell then check the if the following command is running on the
computer where the vncserver is running:
>vncconfig -display :? -iconic -nowin &
the ? has to be replaced with the display of the vncsession.
It is handy to store this line already in the ~/.vnc/xstartup script
