Oh yeah, Arch isn't for the faint of heart, but this should work on any distro running KDE. A quick check tells me Ubuntu is running Gnome 3 by default where you need Gnome Tweak Tool to access the same setting. That sucks, I agree, and I hate that Gnome is trying to go the direction of mobile by locking things down and removing configuration, but considering the OSX doesn't expose this setting at all and you need either the terminal or a 3rd party app to modify it, I also don't think that not having this setting readily available disqualifies Linux from being usable without the terminal, unless we're going to claim the same is true of Macs.
