Jump is compatible with the remote desktop feature available on most Linux systems, however Jump's automatic configuration via a Gmail account is currently not supported on Linux (you need a PC or Mac to use automatic configuration).
You'll need to manually configure Jump with your Linux computer's host address. You can enter the computer's IP address by tapping the plus button ("+") on the top right hand corner of Jump's main screen. Also, be sure to tap the "VNC" button when creating the connection for your Linux computer.
Further more, Jump also has SSH encryption and port forwarding built-in which is also compatible with most Linux SSH servers. We recommend using this feature for better privacy.
