Setting up x11vnc on Raspbian

Tue Jul 24, 2012 8:51 pm

I've been using tightvncserver to sucessfully run remote sessions on my Pi but I'd like to be able to directly view/control the same session as I seen on my Pi HDMI connected monitor.

I understand I need to use x11vnc for this (which I've downloaded and installed) but I'm struggling with Mr Google to find a working example of what parameters to use with it.

Can anyone help please?

I'm sure someone asked a very similar question a few days ago. I don't think it was fully resolved though. I'll see if I can find the thread.

It was here...
http://www.raspberrypi.org/phpBB3/viewt ... 55#p129655

Don't know if you've seen that one (maybe it's where you got the x11vnc thing from?)

As you say - not really resolved :(
For things like this, you need the person who been there and got the t-shirt :)

Ta tho :)

Hello,
I'm no expert but having spent some time trying various methods (without success), the following worked for me:

1. Install

Code: Select all

sudo apt-get install x11vnc
NB I chose not to set a password

2. Auto-start
NB Previously configured auto-login & StartX by following: http://elinux.org/RPi_Debian_Auto_Login

Create new / edit existing ~/.xsessionrc file:

Code: Select all

# Start X11VNC
x11vnc -bg -nevershared -forever -tightfilexfer -nopw -display :0
NB no need to make it executable.

Comments:
-bg : run in background after screen setup. Without it I get a blank / black screen on local (& remote) display - had to SSH-in, to fix via CLI. So, this option seems *essential* for me, though is rarely mentioned!?
-nevershared -forever : on creating a new connection, drop existing. (I only need 1 connection). From x11vnc --help, this combo "guards against hung TCP connections that do not go away."
-nopw : I choose not to use a password; this prevents a warning.
-tightfilexfer : I use TightVNC client
-display 0 : default X11 server display

I use the TightVNC client, as UltraVNC connects but displays solid (red) window, no contents.

Hope this helps.

Cheers,
Pete.

hi Pete
Did you actually try
http://www.raspberrypi.org/phpBB3/viewt ... 62#p108862

because it worked for me and everyone else who's tried it :)

I use is on a daily basis as I'm remoting into battery powered robot RPi.

Its worked with both tightnvcviewer and ultravncviewer, both here at home and in 2 of my schools.

So I think its a runner :)

Hi Simon,

Thanks for your reply. Yeah, I did try that - it's near the end of http://www.raspberrypi.org/phpBB3/viewt ... 63&t=24809

Using the .config/autostart/x11vnc.desktop file, Ultravnc still gives me a solid red(ish) [on Auto] or blue [manual settings] window - no desktop contents.

With hindsight, I abandoned this method due to the above problem (I have) with UltraVNC [Win32, 1.0.9.6.1]; I've just confirmed it works fine with TightVNC.

Thanks again,
Pete.

Hi, first post. Have my headless Pi with x11vnc up and running, using the instructions on this page, thanks. Only issue is that if I boot the Pi without a monitor attached, I end up with a tiny little VNC window, apparently a default monitor size. If I boot with a monitor attached and then disconnect it, the VNC window is the size of the monitor that was previously attached. What do I need to do to tell x11vnc to create a session of a specific window size, e.g. 1920x1080? Thanks...

Figured out that it's not x11vnc that I need to tweek, but it's the X environment, so that when it's headless, it doesn't default to the small 656x416 window size. What do I need to change? A default 1024x768 would be enough for me.

Solved my own problem, got it working by forcing hdmi in config.txt. Defaults to a decent screen size now.

Could you post more details on how you did this?

I think he meant that you have to edit /boot/config.txt and force hdmi display.

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

After making this change i get a decent screen in my vnc connection.
