  This may be a wrong detection by the '''xserver''' or the '''kernel''' itself. So xserver-xorg-input-synaptics has nothing to do with it. In case, filing a bug against the kernel('''linux'''), please note that you should not mark the bug as duplicate even if you can find a closely related bug and you have a strong feeling that the bug should be duplicate. This is a new policy of Kernel Team and it help them to handle the bugs better.
