    Default X11VNC

    Please forgive me if I missed an article actually showing a solution to x11vnc being broken in openSUSE 11.4, I did use the search tool and it brought up zero results.

    Does anyone know:
    A) Why it doesn't just work after being installed like it did in previous versions?
    B) What steps must be taken in order to restore functionality in openSUSE 11.4?

    Any help is appreciated.
    Yes, I have heard of NX, and have no interest in setting it up as x11vnc takes (when it works) all of about 5 seconds to start and then connect to the :0 display.

    Maybe because it is not broken, and works much the same as it has for several years. Are you having problems with the server, client, or both? What exactly have you done, and what (did not) happen?

    You need the following packages installed:
    tightvnc
    x11vnc
    xorg-x11-Xvnc
    xinetd

    Check that the appropriate sections in the configuration file -- "/etc/xinetd.d/vnc" are enabled ("disable = no").

    In YaST:
    Enable "Remote Administration (VNC)" and check the firewall ports are open.
    Enable the "xinetd" daemon in "System Services (Run Level)"

    If you can connect to the server, but see a grey X screen with no GUI login; there is probably a conflict with IPv6 configuration:
    Comment out the " ::1 localhost ipv6-localhost ipv6-loopback" line in "/etc/hosts".

    X server authentication apparently changed.

    I have found that to connect to display :0, I have to run it as root and
    supply the -auth parameter (do a 'ps ax | grep -i xorg' and pull the auth
    parameter from there). The file itself is not world readable, though
    there might be a group setting you can set to read it.

    The other alternative is to enable vino-server on the desktop - that's
    what I do now to get to :0 on my systems. Then I tunnel the connection
    over ssh so it's secured.

    Does vino-server work for KDE?

    Honestly don't know, but don't see why it wouldn't - it runs underneath
    the DM (ie, it interfaces with Xorg), so it should work fine.

    Jim,
    I use krfb for remote support to KDE desktops. The local user has to approve/invite the remote connection. Does vino permit the remote site to connect to the local desktop uninvited as per VNC on MS Windows? That is what I understood from your post, but not from The GNOME Journal: Remote Desktop Administration Using Vino

    There is a configuration option to allow this, yes.

    Awesome, I'm glad we started a discussion on the topic, and I apologize for my ignorance, last time I had checked x11vnc was broke and they hadn't posted a fix anywhere. I am VERY grateful for your feedback!

    Thanks again!

    In searching for a solution to a problem with VNC yesterday, I saw posted in Index of /repositories/X11:/RemoteDesktop/openSUSE_11.4 two new rpms for x11vnc:

    http://software.opensuse.org/search/...m&query=x11vnc
    and
    http://software.opensuse.org/search/...m&query=x11vnc

    I installed these in my 11.4(x86_64)/KDE4.7.1 system and they seem to work for standard user(no need for root) out of the box.

    I spent a few hours over the past few evenings getting this working on my home server running openSUSE 11.3. I did

    I had a heck of a time getting XAUTH working since I was running this server completely headless and so was not logged into gdm at all. After a few hours of wasting time and trying to google it... I went down and hooked up a monitor and logged in like some bank teller from 1980's. :-(

    So... here is the x11vnc command-line options that worked for me.

    x11vnc -nopw -noxdamage -ncache 10 -ncache_cr -geometry 1280x720 -solid blue -auth /var/run/gdm/auth-for-gdm-oJ4HRi/:0.Xauthority -display :0

    To find the correct auth parameters, you will want to ls the directory to get the secret-squirrel text in the directory or perform "ps auxw | grep Xorg".
