Starting the NexCAVE
- make sure you have door access
- check calendar for demos at http://reservations.calit2.net/BrowseForSpace.aspx
- turn on 3 power strips under center screens
- if already logged in, System -> Log off
- log in with user credentials provided (account: neuro)
- open a terminal
- run "gedit mycalvr.xml &"
- make sure the desired plugins are set to "on" in the .xml file (save if you make any changes)
- run "CalVR"
Leaving the NexCAVE
- turn off all the screens
- log out
- close both doors
Troubleshooting
- if a node hangs on a black screen after exiting CalVR, run tentakel killall -9 CalVR
- if a specific node dies, run ssh nexcave-X-X (numbers from the map on the wall) reboot
- if a node still dies, find Philip/Andrew/Joe/Jurgen to hard reboot the server in the server room
- When you start CalVR, if it starts asking for passwords, just keep hitting return until it dies. You should see a "Gnome Keyring has crashed" notification. Wait a minute, then start CalVR again.
Joystick
- If the joystick does not work, first make sure it is plugged in.
- If the joystick still does not work, run the following commands:
cd /home/neuro/CalVR/applications/vrpn_libusb_general /home/neuro/CalVR/bin/libusb_general_server vrpn.xml &
- If it then complains about libusb couldn't open USB device /dev/bus/usb/XXX/XXX: Permission denied, run:
sudo chmod a+rw /dev/bus/usb/XXX/XXX (or get someone with sudo privileges to run it for you)
then run:
cd /home/neuro/CalVR/applications/vrpn_libusb_general /home/neuro/CalVR/bin/libusb_general_server vrpn.xml &
again.
- It will say "Init good." when it has initialized correctly.
