Turn Off Screen Saver in Ubuntu

OK, so CRTs are, like, so 20th Century. If you left them running showing the same image for days on end, like the log on screen in a computer lab, you would eventually find that image burnt onto the screen itself. This is bad. So we invented the screensaver, a bit of software which detects when you have not typed anything or moved the mouse for a while and either blanks your screen, rifles through your pictures collection, or shows some high art animation usually involving toasters. This stops the insides of the CRT from being damaged.

However:
a) no one uses CRTs anymore
b) LCDs do not burn in
c) sometimes I want to leave the screen displaying information without the fucking screen going dark every ten minutes.

Now, I am an intelligent guy, so I go to the System -> Preferences -> Screensaver tool and uncheck the "Activate Screensaver when computer is idle" dialogue box. That should do it?

After ten minutes: blank screen. Oh for fucks sake. So I go to the Power Management options from the Screensaver tool. I tell it 'Never' to put the display to sleep.

After ten minutes: blank screen. Oh for fucks sake. I have to activate the god damned trackpad every nine minutes or so to avoid the screen blanking. Brilliant. I seriously consider trying to activate the trackpad automatically every 9 minutes.

It turns out (and by it turns out I mean after spending the better part of my life trawling through google and forum searches) that you need to change a setting in the gconf file. Whatever the gconf file is. You do this by running this command in a terminal:

gconf-editor

You then navigate through the tree structure until you get to:

/apps/gnome-screensaver/idle_activation_enabled

which you set to false by unchecking it. Hey Ubuntu developers, when someone unchecks the "Activate Screensaver when computer is idle" turn off this bloody setting.

Now, here at the end of all things, sam, I finally have an LCD which does not go dark every 10 minutes.
