Starting Joystick

• Joystick is plugged into USB port.
• Open Terminal window. Note: CalVR and VRPN for joystick tracking will be run in separate terminal windows.
• Navigate to directory containing Joystick tracking executable.
  cd /home/neuro/CalVR/bin
• The "vrpn.xml" configuration file should already be in this directory, but if not, the most up to date file location is: "/home/neuro/CalVR/applications/vrpn_libusb_general/vrpn.xml"
• Type the following command into the terminal
  ./libusb_general_server

• There are a few possible ways that this command may not run properly.
  • If the output from the terminal indicates that the "vrpn.xml" configuration file was not found, use the following command:
    ./libusb_general_server XXX
    Where "XXX" is the absolute path to the "vrpn.xml" configuration file.
  • If the terminal output indicates that:
    libusb couldn't open USB device /dev/bus/usb/XXX/XXX
    There are two solutions:
    • Run the previous command again as a sudo command.
      sudo ./libusb_general_server
    • Modify permissions of the USB joystick. sudo chmod a+rw /dev/bus/usb/XXX/XXX and run the previous command again.
    • Note: Both solutions require sudo privileges. If you do not have sudo privileges, have a user that does and run the second command to modify the permissions of the USB device.

Troubleshooting

• To confirm that the Joystick is plugged in to the head node, open a terminal and type in the command

 lsusb

and hit enter.

You should see

 Logitech, Inc. ATK3 (Attack III Joystick)

among the listed USB devices.

• if a node hangs on a black screen after exiting CalVR, run tentakel killall -9 CalVR

Starting OpenAL Audio Server for NexCave

• VNC into Server (IP: 137.110.116.10) Note: This currently does not work. Either a separate VNC server needs to be installed or the Mac installed VNC server needs to add a user for linux VNC connections.
• Start Jack Router.
  • Launch the Jack Pilot app.
  • Click start.
• Launch OAS.
  • Open a terminal.
  • Type: cd OAS/Open-Audio-Server/server/build/bin
    Then: ./OAS oas_config.xml

• Note: If VNC does not work, access the server from its physical location in the server room (1608 B).
