    session manager authentication problems


    Hi,
    I've recently installed FC5 on my AMD x86_64.
    I am working iwith VMD witch is a molecular visualization program that uses openGL (it use to work just fine on my FC4). Whenever I try to run it on the FC5 it seems to open for less than a second and then it quits. When I tried to run it as root I got this warning:

    Warning: Tried to connect to session manager, Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed

    Does anyone know how to fix this? I am assuming that it is a problem with the session manager rather than the program I am runnig but I am not sure.

    Thank you for you're help.

    Jonathan.

    Are you trying to run this program as root, or as a user?

    Anyway that only means that the program you are trying to launch doesn't have the autorization to connect to your current X session.

    Verify a few things:

    1) Are you able to login to a X session?

    2) Do you have this line in your /etc/network/interfaces:
    Code:
    127.0.0.1  localhost.localdomain localhost
    3) Check the log of your login manager. If GDM, then
    Code:
    cat /var/log/gdm/\:0.log

    when I log in as user or root the program just won't run - it will just seem to opent for a sec and close. when I logon as user and go to super user mode it gives the warning as above.

    I do have the local host lione in my config file.

    my gdm log reads:

    I have deleted several other threads that asked this same question. Do not ask the same question in more than one section of the forum.
