Since you did not mention using su with a new username or ssh I am assuming:
A. you are not concerned with remote systems
B. you are referring to using 'su' to switch to the root user
C. you have the root password to do so
the simple solution here is sudo.
as root (use 'su' regularly the first time) issue the 'visudo' command to edit the '/etc/sudoers' file. Add a line like:
%wheel ALL=(ALL) NOPASSWD: ALL
visudo will open the file in vi/vim.
now add your user to the wheel group:
usermod -G <username>
where <username> is your username and NOT root.
now to su to root without a password simply type the command 'sudo su -' and to run a command as root without switching to root just type 'sudo <command of choice>'
cheers!

qshutdown
qshutdown(1) General Commands Manual qshutdown(1)
NAME
qshutdown - An avanced shutdown tool
SYNOPSIS
qshutdown [options]
DESCRIPTION
qshutdown is a simple tool to choose a time or a number of minutes to shutdown, reboot, suspend or hibernate after.
qshutdown will show itself 3 times as a warning if there are less than 70 seconds left. (if 1 Minute or local time +1 Minute was set
it'll appear only once.)
This program uses qdbus to send a shutdown/reboot/suspend/hibernate request to either the gnome- or kde-session-manager, to
HAL/ConsoleKit/DeviceKit/UPower and if none of these works, the command 'sudo shutdown' will be used.
OPTIONS
-h --help
Prints options with description.
-i Prints information about qshutdown.
-v Prints all errors and warnings.
NOTES
When sending the request to HAL or ConsoleKit, or the shutdown command is used, the Session will never be saved. If the shutdown command is
used, the program will only be able to shutdown and reboot.
If nothing happens when the shutdown- or reboot-time is reached, it means that one lacks the rights for the shutdown command. In this case
one can do the following: Post the following in a terminal:
$ EDITOR=nano sudo -E visudo
and add this line:
* ALL = NOPASSWD:/sbin/shutdown
whereas * replaces the username or %groupname.
For admins:
If you want qshutdown to run with "parental lock" for every user, you can do
$ sudo cp /usr/share/qshutdown/autostart/99qshutdown /etc/X11/Xsession.d/
and set the option Lock_all in /root/.qshutdown/qshutdown.conf to true. Note that qshutdown has to start once to generate the qshut-
down.conf. Furthermore there is a need to do
$ EDITOR=nano sudo -E visudo
and add the following line to the sudoers:
* ALL = NOPASSWD:/usr/bin/qshutdown
If you should ever forget your set password, just remove the whole line starting with Password manually from the qshutdown.conf.
FILES
The configurationfile (and logfile) is located at ~/.qshutdown/ (under Linux/Unix). The maximum Number of countdown_minutes is 1440 (24
hours).
KNOWN ISSUES
There is no system tray icon for qshutdown in Ubuntu 11.04.
SOLUTION: Type the following line in a terminal:
$ gsettings set com.canonical.Unity.Panel systray-whitelist "['all']"
HINTS ON USAGE
If you want qshutdown to stop "bugging" you, just remove the hook from "warnings on?".
HOTKEYS
Ctrl+I information window
Ctrl+Q Quit
Ctrl+P Prefereces
Ctrl+L write the run time once into the logfile (works
only if qshutdown quits. To make it permanent set it in the preferences.)
Ctrl+S set to shutdown
Ctrl+R set to restart
Ctrl+U set to suspend to RAM
Ctrl+H set to hibernate
Ctrl+E stop timer (only if the countdown has started and
the admin didn't restrict the access)
Shift+E to edit the config file (for this a password is
necessary. If you are a user, you can set an "empty password" (leave the password field empty)).
