In older versions of Ubuntu when you pressed Ctrl+Alt+L it would lock and blank the screen (start the screensaver). In 14.04 it just locks the screen.

How can I get it to lock AND blank the screen?

Open System Settings and navigate to Keyboard -> Shortcuts. Open the "System" section, click on "Lock screen" and press Backspace. This will disable the system lock screen shortcut.

Now click the + button. A dialog will pop up asking for your input. Add a custom name and put:

gnome-screensaver-command -la  

in the "command" field.

Click "Apply". Now click "disabled" next to the shortcut you just created and press the key combination you want to use to lock and blank the screen.
