Thread: VNC viewer is connected but blank screen

  1. VNC viewer is connected but blank screen

    I was able to run a vncserver and connect to it without a problem.
    After switching to xfce from kde, viewer connects but all I get is a
    blank screen with mouse working.

    I am running the server on a Kubuntu machine. I tried connecting to it
    via TightVNC from a Windows machine as well as via vncviewer to
    localhost from the Linux server itself.

    When I run the server I get the following log:

    4/03/08 13:32:12 Xvnc version 3.3.7 - built May 24 2007 12:47:11

    24/03/08 13:32:12 Listening for VNC connections on TCP port 5901

    When I connect from the client using vncviewer, this additional
    message is received:

    I don't know how to debug it and logs do not tell much. Does anybody
    have any idea what would be the cause?

    Thanks...

    sounds like your not starting a xfce session manager if you want to run
    xfce. Do you have:

    /usr/bin/xfce4-session
    in your xstartup and does
    ps -aef | grep xfce
    show some xfce processes running after you start your vncserver?

    VNC is only going to show what's on the screen of the remote machine.
    What is that remote screen displaying?

    You have now created a screen called 'cellular:1'.

    Looks good, you're now connected to the screen 'cellular:1'.

    The screen is blank because no programs are running that might put
    output on that screen. You need to run some program, like a window
    manager or an terminal.

    David, how do I run the programs. Does that mean that my x-session is
    not starting properly? With KDE only configuration, all I had to do
    was to run vncserver and it was running the window manager itself.

    Looks like the problem is not connection but x-session not running.
    Even though at many sites switching from kde to xfce is said to be
    easy, going back and forth gives many problems.

    Thank you Jack. Where is the "xstartup" file located? Do I need to
    manually edit it to run the x-session?

    On my Fedora install, when you start vncserver for the first time,
    it creates a ~/.vnc directory with a xstartup script in it.
    I changed my xstartup scrript to do:

    #!/bin/sh

    # Uncomment the following two lines for normal desktop:
    # unset SESSION_MANAGER
    # exec /etc/X11/xinit/xinitrc

    /usr/bin/xfce4-session &
    wait


    so when vncserver starts, it starts an X session and the
    xstartup script starts my xfce4-session manager.

    Thank you for the detailed explanation. I actually uninstalled
    Xubuntu using the directions at http://www.psychocats.net/ubuntu/purekde
    and re-installed the KDE desktop. Everything works now. Note that
    running simply "sudo apt-get remove xubuntu-desktop" does not work. I
    will follow your directions if I decide to switch to xfce.

    xfce is just supposed to be a trimmed down x-windows desktop. I use
    it for all my remote, vnc sessions. it's fairly responsive and functional
    over the slower links.

    Thanks Jack. I installed xfce4 back and updated the xstart file as you
    suggested. it works perfect.. It is definitely a neater interface, I
    will use this one for remote access..
