6. Run the command /usr/pubsw/bin/vncserver.glx

7. You must note the number value that is returned for your remote desktop. In this example the value is 1.
You do not normally need to run steps 5-7 every time you connect. Unless your workstation has rebooted or you have explicitly killed your VNC server process, the vncserver.glx program will still be running. After connecting to your workstation run /usr/pubsw/bin/vnccheck to see see if the process is still running.
