It doesn't seem that your x11vnc is actually starting from this error message. Do you have X running on the BBB ? If you have X running, do this: ps ax | fgrep -- -auth /usr/bin/X :0 vt7 -nr -nolisten tcp -auth /var/run/xauth/A:0-Hu3Jac See that '-auth /var/run/xauth/A:0-Hu3Jac' ? You will have something similar, use that like this, replacing where appropriate: sudo x11vnc -auth -auth /var/run/xauth/A:0-Hu3Jac You can usually go without the '-auth' as long you run x11vnc as the user that started X. regards, Nuno - -- http://aeminium.org/nuno/ -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJSkLtnAAoJEPIY6fuKMkz5yHMP/3dETeRLQNkPp8CP6w7EtTwf Crw3/cN/IHEK+arwBcfZCJ+5P41Evwz8wKW0rAq189YQ+R1dGFxS2AMzE+jV3ONO g6iHIWHQhEaROVmCcF2FmEAmU+Duy12Nx0bONcwrPstXAAIjt40aaU0NLLiYSsFn OjsXqesi3cbWsYO72K+XQUci1M7XkVp90HQBVJcKzkAvaw+kBXExBDMeQVwLpFkf ueAQ9b7+lR0sMusPTyncwRwhGTG7If3UDM/PDmsJ7RIxqeTTpbvG/YnzfNWfW4YI msql/V7W4RWnmKN7oQ2MqoN7DewudTRUb5HFisytkqEYk0PlgUMcn6LSgDRkrFVt 7t5ot83CRjy5zU6WNDh1+L1DCchFbNCBV8GOrqajv5rUG98fvaKXi+dnppEo4thM sXOj2PcnXyknzxKYZEI1ds3Nw0yT0xh4YKnA72pyv9PqeDE8PrAKJzx3/ao0jkwM gXQpWfwmt3AiatUxf0v3D7OEu7fajDJX6uWPesTzwLa0niaUeIB2JrSU9N2y1Pz2 WrrvE3IuZYVR1051C2t3xmLk1pEJCBef92pani/IQZMAiYmCd6ZyCzc7oLBCCEru N4QvVr9pzqHpZgOcw6lHCv+P2YZMKPgH6eG4Smdia41QuHd1rLXz2YXMCZ0E8fvv MQen9My/8mTxdIF2wEwC =U+kT -END PGP SIGNATURE- -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Re: [beagleboard] setting up VNC for ubuntu
You need to specify the port number too. e.g. xxx.xxx.xxx.xxx:1234
If that doesnt work then i have no idea.

[beagleboard] setting up VNC for ubuntu
I am trying to set up VNC from a WIn7 PC into the BBB I am running ubuntu
on the BBB.
on the terminal:
ubuntu@arm:~$ sudo apt-get install x11vnc vnc-java
ubuntu@arm:~$ x11vnc -storepasswd (wrote my password)
ubuntu@arm:~$ x11vnc -foreever -usepw
Password written to: /home/ubuntu/.vnc/passwd
22/11/2013 18:22:19 x11vnc version: 0.9.13 lastmod: 2011-08-10 pid: 1926
22/11/2013 18:22:19 XOpenDisplay("") failed.
22/11/2013 18:22:19 Trying again with XAUTHLOCALHOSTNAME=localhost ...
22/11/2013 18:22:19
22/11/2013 18:22:19 *** XOpenDisplay failed. No -display or DISPLAY.

22/11/2013 18:22:19 *** 1 2 3 4
22/11/2013 18:22:23 XOpenDisplay(":0") failed.
22/11/2013 18:22:23 Trying again with XAUTHLOCALHOSTNAME=localhost ...
22/11/2013 18:22:23 XOpenDisplay(":0") failed.
22/11/2013 18:22:23 Trying again with unset XAUTHLOCALHOSTNAME ...
22/11/2013 18:22:23
22/11/2013 18:22:23 ***
22/11/2013 18:22:23 *** XOpenDisplay failed (:0)
*** x11vnc was unable to open the X DISPLAY: ":0", it cannot continue.
*** There may be "Xlib:" error messages above with details about the
failure.
Some tips and guidelines:
** An X server (the one you wish to view) must be running before x11vnc is
started: x11vnc does not start the X server. (however, see the -create
option if that is what you really want).
** You must use -display , -OR- set and export your $DISPLAY
environment variable to refer to the display of the desired X server.
- Usually the display is simply ":0" (in fact x11vnc uses this if you
forget
to specify it), but in some multi-user situations it could be ":1", ":2",
or even ":137". Ask your administrator or a guru if you are having
difficulty determining what your X DISPLAY is.
** Next, you need to have sufficient permissions (Xauthority)
to connect to the X DISPLAY. Here are some Tips:
- Often, you just need to run x11vnc as the user logged into the X session.
So make sure to be that user when you type x11vnc.
- Being root is usually not enough because the incorrect MIT-MAGIC-COOKIE
file may be accessed. The cookie file contains the secret key that
allows x11vnc to connect to the desired X DISPLAY.
- You can explicitly indicate which MIT-MAGIC-COOKIE file should be used
by the -auth option, e.g.:
x11vnc -auth /home/someuser/.Xauthority -display :0
x11vnc -auth /tmp/.gdmzndVlR -display :0
you must have read permission for the auth file.
See also '-auth guess' and '-findauth' discussed below.
** If NO ONE is logged into an X session yet, but there is a greeter login
program like "gdm", "kdm", "xdm", or "dtlogin" running, you will need
to find and use the raw display manager MIT-MAGIC-COOKIE file.
Some examples for various display managers:
gdm: -auth /var/gdm/:0.Xauth
-auth /var/lib/gdm/:0.Xauth
kdm: -auth /var/lib/kdm/A:0-crWk72
-auth /var/run/xauth/A:0-crWk72
xdm: -auth /var/lib/xdm/authdir/authfiles/A:0-XQvaJk
dtlogin: -auth /var/dt/A:0-UgaaXa
Sometimes the command "ps aux | grep auth" can reveal the file
location.
Starting with x11vnc 0.9.9 you can have it try to guess by using:
-auth guess
(see also the x11vnc -findauth option.)
Only root will have read permission for the file, and so x11vnc must be
run
as root (or copy it). The random characters in the filenames will of
course
change and the directory the cookie file resides in is system dependent.
On the Windows PC I installed RealVNC and open it to 192.168.7.2 and it
keeps giving me "Connection Refused 10061"
Cannot find a good solution online.
Any help would be appreciated
Bill
