[Ubuntu] x11vnc

[RabbieBurns]

installed x11vnc and set up a password for it with

x11vnc -storepasswd

but it doesnt prompt for a password it just lets me straight in? Also tried

x11vnc -forever -usepw

but same.

What bit am I doing wrong?

From memory (and it was a while ago) I used to use -rfbauth ~/.vncpasswd

[RabbieBurns]

running that doesnt return me to the terminal just sits there...:

Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval.  It should work with any VNC viewer.  Try it by running:

    x11vnc -ncache 10 ...

running that doesnt return me to the terminal just sits there

That's what the -forever switch is meant to do. I have these notes in my setup checklist for Ubuntu 9.04 (password changed to "bananas" as an example):

apt-get install x11vnc
mkdir /root/.vnc/

x11vnc -storepasswd bananas /root/.vnc/passwd

Add to /etc/rc.local:
sleep 5
/usr/bin/x11vnc -o /var/log/x11vnc.log -rfbauth /root/.vnc/passwd -auth /var/lib/gdm/:0.Xauth -display :0 -noxfixes -loopbg -forever

Edit BOTH /etc/gdm/gdm.conf-custom and /etc/gdm/gdm.conf:
In [daemon] section, make sure you have the line:
KillInitClients=false

Reboot

The above results in a 9.04 machine that, on boot, lets you log in and control the machine's display.
