PROBLEM:
Can't remote access lubuntu server with Vino but can ssh it.
DESCRIPTION:
You open a ssh tunnel (map remote 5900 port to local 12345 port) of remote lubuntu station (ex: 192.1.1.180) at terminal client side to remote access lubuntu station.
Example to type at cmd prompt:
ssh -L 12345:localhost:5900 user@192.1.1.180
note: change "user" and address (192.1.1.180) with your own ID.
You open a second terminal window at client station to start vnc with cmd:
xvncviewer localhost:12345
Error msg client side:
xvncviewer: VNC server closed connection
Error msg server (the ssh terminal) side:
channel 3: open failed: connect failed: Connection refused
DIAGNOSE:

SOLUTION:
At cmd prompt type (remote server side):
export DISPLAY=:0.0
/usr/lib/vino/vino-server
Error msg:
