The problem I'm running into is that the GUI (settings > sharing) seems to have absolutely no control over vino-server.

In the GUI, I can toggle screen sharing on and off, tweak the security settings, etc. The GUI shows the  ...

How can I make KRDC show a pointer instead of a tiny circle for the remote host's pointer?

The 'show local pointer' option allows me to turn the circle off, but then I have no visible pointer at all at the Linux end!
