first of all, general wisdom is to use a normal account for everyday activities and only switch to root when you need to perform system tasks.
so, you can log in as the normal user, then when you need to be root, run the command
when you're done working as root, run
if you still want to log in as root directly, and if you use kde, go to Control Center -> Login Manager -> Users. there you can unhide the root user. if i remember correctly from the time i used mandrake, it will warn you that you shouldn't log in as root that way.
