Logging into VNC session

Once connected to squiggles over ssh

Creating a VNC session

VNC sessions will be created at bootup using the port numbers above If the VNC session fails or is not working: vncserver :## -geometry 1900x1200 (This will open a vnc session on port 59## with a resolution of 1900x1200) The ## must match your port number for this to work.

Connecting to a VNC session

Use realvnc viewer to log into your VNC session.

VNC viewer download

Log in using RealVNC

Open vncviewer In the top bar that accepts a VNC Server address
type localhost:## (where ## are the last two digits of your port number 59##)
