Disabling screensaver on LXDE

Caffeine wasn't working for me. I got an error like this:

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ScreenSaver was not provided by any .service files

Bug 1280449 contained the solution for me. Thank you Paulius Vitkus:

sudo apt-add-repository ppa:behda/ppa
sudo apt-get remove caffeine
sudo apt-get update && sudo apt-get install caffeine
