newbie: no shutdown or root login in gnome desktop manager
I have a dual boot (Win XP + Debian Linux 3.0 r1), and someone installed gnome desktop manager to me, it seems like KDE, but I don't understand why I can't login as root from the login screen, I can't even stop the login screen before coming up tp login from command prompt, so, I uncleanly close the system, and then next time it firces checking the disk (fsck), and when it fails, It allows me to login as root to fix it manually, and this GUI allows me only to login as a normal user, and no shutdown is available to users, only root can shutdown the system, so I am stuck
is there a way to change this version of GUI, or add a root login, and shut down for normal users,
then, I need to configure dialup on it, and don't know how?
also, I need to configure it to read a usb drive as well?
sorry I am new to Linux, and have a lot to do with it, I appreciate any help I get, thanks,
