I followed the instructions in the Adafruit tutorial for setting up vnc for my RPi (http://learn.adafruit.com/adafruit-raspberry-pi-lesson-7-remote-control-with-vnc). VNC works great when launching vnc directly from the terminal (using vncserver :1). When I launch vncserver on boot (following the tutorial instructions):
