Can't start VNCServer - User enviroment not set

[xxxxxx]

Hi there,

I am trying to start my VNC server using the kali menu > services > Start VNC Server > on all interfaces.

The terminal returns
vncserver: the USER enviroment variable is not set.
Display Number:X will be port 590X.
Press any key to continue...

Is there a way I can get it to work ?

I am running it on a Note 4.
