Off hand, that behavior sounds much like you have X-clients installed,
but not an X-server; the VNC software on the Beagle may be acting as the
server when it is running. cf:

See above answer... Your X clients (applications) are sending drawing
commands to the VNC server on the Beagle, which relays them to the VNC
client on the other computer for display. Note: the desktop manager is a
/client/ application. {Note: the usage of server/client WRT VNC is opposite
of the usage for pure X Window. In X, the /display/ doing the rendering is
the server, clients send commands to the server over the network -- But
with VNC, the software on the Beagle is intercepting the commands and
reformulating them for VNC network protocol}

packages):
