Angstrom and VNC on Beaglebone

I have been trying to set up an Angstrom system so it is possible to connect to it using VNC, but without any luck. I have found lots of suggestions to how this should be done, but none detailing a success. The working setups all seem to use Ubuntu.

Does anyone have a step-by-step guide to this?

This is what I have done:
I have used this image:

Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.05-beaglebone-2012.05.09.img.xz

And installed

x11vnc
angstrom-x11vnc-init

If I then run

x11vnc -create

I see:

13/06/2012 09:42:17 x11vnc version: 0.9.13 lastmod: 2011-08-10 pid: 373

13/06/2012 09:42:17 Listening also on IPv6 port 5900 (socket 4)

13/06/2012 09:42:17

The VNC desktop is: beaglebone:0

PORT=5900

So far so good…
But when I try to connect, I get the following error:

The program “Xvfb” could not be found in PATH and standard locations.

You probably need to install a package that provides the “Xvfb” program.

Without it FINDCREATEDISPLAY mode may not be able to create an X display.

Unfortunately there is no Xvfb package available for the beaglebone if I search for xvfb: opkg update ; opkg list | grep xvfb

If I check the feed browser at http://www.angstrom-distribution.org, I can find xserver-xorg-xvfb for arm7a architectures, but not for v2012.05 eglibc

Same problem here, do you know whether there was any progress on this issue, or did you solve the problem?

Thanks a lot.

Nope, I never found a solution. Since I needed this functionality for my project, I gave up on Angstrom, and moved to Ubuntu, where it was very easy to set up.

I haven’t been on my beaglebone in a while, but I was able to use x11vnc and put the command in /etc/rc.local . The command syntax is something like :

code:
x11vnc -display :0 -forever -passwdfile /point/to/passwd/file

Also if you read the help for x11vnc it is very easy to make it listen only to localhost, and setup ssh for stronger encryption.
