I've been using two finger scrollling for a while now and I've really gotten used to it, but suddenly it has stopped working in both Ubuntu karmic and Fedora constantine. I'm really hoping this is a GNOME issue and not my mouse going out

The option for two finger scroll is even grayed-out in fedora under Preferences > Mouse > Toucpad, but in ubuntu I can still select it.
Can anyone recommend anything or at least confirm they have a similar problem and that my mouse isn't going out

This laptop is way too new for that kind of junk to be happening yet.
