Comment 56 for bug 701060

Are these procedures safe on a production machine that just has to work at all times?

 - if logged in, log out
 - switch to VT1 with Ctrl+Alt+F1
 - log in as root (or log in as admin user and run sudo -s, if you don't have a root password)
 - run 'service gdm stop' to shut down X
 - run 'service plymouth start' to start the plymouth daemon
 - run 'plymouth splash; sleep 30; plymouth quit' as a single commandline
