    THANK YOU TO ALL THAT RESPONDED SO QUICKLY!!!:

    Charlie summed it up best when he asked the question I
    should've included information for in the first place:

    Are you logging in as root or as a different user
    account and then su'ing to root?

    I am su'ing to root. Well...

    Charlie Ballowe:

    Unlike Linux, Tru64 doesn't pass along X credentials
    with a su.

    try:
    DISPLAY=hostname:0
    XAUTHORITY=~username/.Xauthority
    export DISPLAY XAUTHORITY

    then run your command.

    I did just that and it worked like a charm. Thank you
    all once again...

    Initial problem below:

    Managers,

    I'm hoping I can get some help with this situation.
    It is probably
    something simple that I'm overlooking:

    I have a A8400 system running TRU64 5.1a with a
    graphics terminal connected
    to it. I am able to login to the system and
    manipulate the CDE just fine.
    The problem occurs when I try to open up an
    application such as
    'dxaccounts'. I get the following error message:

    dxaccounts: Cannot open display

    Not a problem yet. I didn't think I have to provide
    any display parameters
    when opening up a GUI from the console, as the host
    properties would already
    be set. So, I try to give it the proper $DISPLAY
    values:

    (/bin/ksh)
    # export DISPLAY=hostname:0.0

    I now get the following error message:

    Xlib: connection to "hostname:0.0" refused by server
    Xlib: Client is not authorized to connect to Server
    dxaccounts: Cannot open display

    What am I missing? Thank you in advance...
