You can connect to Ponyland using VNC.
First, connect to one of the servers on Ponyland, and run the following script (on any machine, as long as it's not the old Applejack applejack.science.ru.nl):
<property name="<Super>Tab" type="string" value="switch_window_key"/>
<property name="<Super>Tab" type="empty"/>
If you prefer to start the VNC server manually, that's fine, but please use the following script to determine your display number:
/vol/customopt/config/scripts/vnc/vncdisplay.py ># Display number for johndoe is :20
It will permanently assign a unique display number to you. If everyone uses this script, there can never be conflicts.
