The ubuntu package has been fixed. You can find the launchpad bug here : https://bugs.launchpad.net/debian/+source/xserver-xorg-input-synaptics/+bug/68370 And the source package here : http://packages.ubuntu.com/gutsy/x11/xserver-xorg-input-synaptics I'm not sure if a patch has been made, I think that the package just got fixed. -- Saïvann
