reenabling root password

There are some applications, which require the root password in X. How can I run them? I tried "passwd" as root, but it didn't help... :(
How can I enter the default blank password?

Try sudo passwd or sudo < app >.

Try this script, prompts and all:

Code:

---

#! /bin/bash
# name beroot
clear
echo
echo
echo FIRST: Change the password for root
echo
sudo passwd root
echo
echo Now actually log in as root and run mc
echo
su root -c mc
# remove the -c mc above to NOT run mc
