F13 how to enable system-wide tapping

[kto]

Hi guys, it's me again
I was wondering how I can enable systemwide and desktop-independent touchpad-tapping. I found a tutorial for f11 and f12, but its not working with f13.
My current pseudo-solution is to start gnome-mouse-properties, whenever I start XFCE, but that's not really what I want, obviously.
It would be nice if someone of you knows how I can achieve this the right way.

After a lot of searching and trying I found a solution to this.
What you have to do to enable system-wide tapping is to add the following lines to the InputClass-section in the file /etc/xorg.conf.d/10-synaptics.conf:

	Option "TapButton1" "1"
	Option "TapButton2" "3"
	Option "TapButton3" "2"

I don't know if a desktop environment different from XFCE will override this once you log in. Just try it and post your results here (although it doesn't seem like there are people who are interested in this).
At least, this worked for me and I can now use my touchpad to click in GDM and XFCE.

Edit: Well, this is awkward. Seems like someone hates me a lot ^^. One minute after i wrote this, i did a yum update, which updated my xorg-x11-drv-synaptics package and removed the file mentioned above. But I found it again, it is now in /usr/share/X11/xorg.conf.d/50-synaptics.conf.
