    Question XDMCP & gdm remote login Bug?

    Hi all,
    I am trying to figure out why I can't access my Desktop from a remote machine.

    My configuration:
    server runs openSUSE 11.1 with gnome Desktop (gdm)
    client runs openSUSE 11.0 with KDE Desktop (kdm)
    (both 64bit)

    What I did (on server):
    in /etc/X11/xdm/xdm-config I checked for
    !DisplayManager.requestPort: 0

    I enabled graphical remote login in yast!

    I stopped the firewall (on both machines)!

    Softwareversions (installed packges):
    Kernel 2.6.27.19-3.2-default
    gdm-lang-2.26.0-2.10
    gdm-branding-openSUSE-11.1-1.36
    gdm-2.26.0-2.10
    xorg-x11-libXdmcp-devel-7.4-1.31
    xorg-x11-libXdmcp-7.4-2.1
    (I also tried gdm 2.24 and libXdmcp 7.4-2 -> no effect)

    What works fine:
    I can access the X Desktop through xdmcp on my local machine typing: X -query localhost :1
    I can access another (kdm) Desktop from the client machine typing: X vt8 :1 -query ANOTHERHOST

    When I access my server:
    I type: X vt8 :1 -query server
    X starts and the grey screen appears with the X-Mouse-Cursor in the middle.
    Now the Mouse turns into a pointer and the background gets a new grey structure.
    From this point on it hangs. (Mouse and Keybaord are dead)

    Useful output could be:
    in /var/log/gdm/server:1-greeter.log:
    Fenstermanager-Warnung:Schwerwiegender E/A-Fehler 11 (Die Ressource ist zur Zeit nicht verfgbar) auf Anzeige ::ffff:132.180.193.116:1.0.
    gdm-simple-greeter: Fatal IO error 104 (Die Verbindung wurde vom Kommunikationspartner zurckgesetzt) on X server ::ffff:132.180.193.116:1.0.
    gnome-session: Fatal IO error 11 (Die Ressource ist zur Zeit nicht verfgbar) on X server ::ffff:132.180.193.116:1.0.
    in /var/log/messages:
    gdm-simple-slave[19098]: WARNING: Child process -19115 was already dead.
    gdm-simple-slave[19098]: WARNING: Unable to kill D-Bus daemon
    This is all I have. In /etc/gdm/custom.conf I set:
    # GDM configuration storage

    [xdmcp]
    # SuSEconfig: displaymanager:DISPLAYMANAGER_REMOTE_ACCESS
    Enable=true

    [chooser]

    [security]
    # SuSEconfig: displaymanager:~DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN
    DisallowTCP=false
    # SuSEconfig: displaymanager:DISPLAYMANAGER_ROOT_LOGIN_REMOTE,DISPLAYMANAGER_SHUTDOWN, security:PERMISSION_SECURITY
    AllowRemoteRoot=true

    [debug]
    Enable=true
    But this did not help.

    Any ideas how to solve the problem? Is it a Bug?

    Since I'm having the exact same problem, I was wondering if any solution has been found in the meantime...


    BTW, Marvin, what was the graphics card driver you'd been using?

    Hi again,

    I worked a lot an that problem in the last weeks. My conclusion is: It simply does not work. The xdmcp between gdm and kdm is not supported. Instead you can try a VNC connection.

    I was using an NVIDIA graphics driver of version 180.51

    If somebody has proofed the opposite please tell me

    However it's not only when the login omes from kdm - the nomachine nx server produces exactly the same sequence of errors when trying to connect to gdm ...
