vncviewer connect to primary display of lightdm on debian jessie (share with physical desktop)?

by

My server setup is: Debian jessie with lightdm DM with only modified changes section to sudo cat /etc/lightdm/lightdm.conf:


[VNCServer]
enabled=true
command=Xvnc -rfbauth /home/abarik/.vnc/passwd
port=5900
listen-address=localhost
greeter-session=lightdm-gtk-greeter
user-session=gnome
width=1024
height=768
depth=24

I also have a desktop with primary monitor attached to it with default DM to lightdm.

My client setup: vnc client is vncviewer on mac (OS X)

How do I make sure that, if I VNC into the server from client, I reuse the primary physical display? If thats not possible, how do i keep atleast one of my virtual port 5900 active even after disconnecting?

Answer

I think X11vnc is what you want.

X11vnc provides ability to connect your physical monitor.

For lightdm, you can use the following line.

x11vnc -display :0 -auth /var/run/lightdm/root/\:0

If you want to run it constantly, you can add –loop flag like.

x11vnc -display :0 -auth /var/run/lightdm/root/\:0 --loop
