Gentlepeople, Although I have found a work around to this problem, I would still like to know why it doesn't work properly, and why my work around works when it prints a message on my terminal saying authentication failed!
So: (1) When I click the menu item "GDM Configurator", I get an error dialog saying: "You must be the superuser (root) to configure GDM". I am not offered any way of entering a root password before I get this error. This happens on a number of menu items so I would like to fix the root cause of the problem rather than working around it all the time. (2) I found the program to run by inspecting the menu item properties. (a) After logging into GDM as me (a user) I then logged into a terminal session as root and tried to run the command. I got the error message: "Gtk-WARNING **: cannot open display:". There is a way to specify the display, and I added "--display=:0" (which I got from the display environment variable), but now I get the errors: "Xlib: connection to ":0.0" refused by server" and "Xlib: client is not authorised to connect to server". Doesn't root have permission access this user initiated server? How can I connect as root? (b) So I tried su'ing the command directly: "su -c gdmconfig". This prompted me for a password. I entered the root password and voila, the GDM Configurator started in spite of the following error: "GnomeUI-WARNING **: While connecting to session manager: Authentication Rejected, reason: None of the authentication protocols are supported and host-based authentication failed." I was still able to enable the session menu so I could shutdown my machine from the GDM login screen. And it was there and worked the next time I got to the GDM login screen. Clearly the error is a warning and obviously not cataclysmic, but it all makes me feel I don't understand what is going on (I don't) so if anyone can help, it would be much appreciated.
