After installing Leap Motion https://www.leapmotion.com/setup/desktop/linux/ I was trying to run it.
sudo leapdConfiguration file not foundResetting /var//.Leap Motion/config.json.[Info] WebSocket server started[Info] Secure WebSocket server started...and thats it...does not seem to work.
Not sure what to do next. Also, I am newbie in Linux.
The issue has been resolved.
I re-installed it.
then ran sudo service leapd stopsudo leapd
then opened a new terminal to callVisualizer
I hope other Linux users will find it useful.
