I have installed Ubuntu v5.04, with its default GDM, I was able to enable root login through the GNOME GUI.
Since then I had installed KDE and and made KDM the default login manager. And I think I had enabled the root login on KDM through the KDE GUI as well. I can see the option of root is checked from the KDE's control centre.
However, I can't change the login settings. With my normal account, I would be prompted password to change those settings, but after entering the password, either the windows freezes or it jumped back to the parent page, so I can't touch any of the login settings. And since I can't login as root from KDM, I can't try it out with root setting.
Now my questions are:
1. What's wrong with the control centre? What can I do?
2. How do I switch the default login manager to GDM?
3. I can login as root from the command prompt, and when I execute startx it would bring me to GNOME. How do I get into KDE from the command prompt?
Thanks in advance.
