Well you could open terminal by pressing CTRL+ALT+T

then simply type :

-for shutdown:

sudo shutdown

or

sudo poweroff

-for restart:

sudo reboot

As far as I am aware, there isn't a system shortcut for shutdown, but you could create one. Read Are there any Keyboard Shortcuts to Shutdown?

I've got a nice one for you:

Shutting down by using a hotkey

1. Install consolekit:

    sudo apt-get install consolekit

or use the Ubuntu Software Center: consolekit

2. Press Super, then type Keyboard, then click on the Keyboard icon

3. Click on Hotkeys

4. Click on Custom hotkeys

5. Add a new entry by clicking on the + sign:

Name: Shutdown

Command:

 /usr/bin/dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Stop

6. Now click Apply, then click in the second column to assign a hotkey.

7. Press any hotkey combination you desire. For instance: Ctrl+Alt+U

8. Enjoy!

Reboot, hibernate, suspend

If you want to restart instead, replace said command by:

dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Restart

If you need to hibernate, replace it by:

dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Hibernate

Finally, if you're looking for a suspend shortcut, use this one:

dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend
