Not been able to Shut Down 13.04

Solution 1:

I've solved the problem through those steps:

I opened the terminal and with nano opened the file below:

sudo nano /etc/default/speech-dispatcher

Inside the file I changed the RUN property to yes, so the file started looking like this:

# Defaults for the speech-dispatcher initscript, from speech-dispatcher

# Set to yes to start system wide Speech Dispatcher
RUN=yes
