"Binary package hint: udev (but not quite sure)
On my Lenovo T60 the Touchpad works great until I login using GDM.
After 2-3 seconds I've pressed "Login" it suddenly stops working and I must use an external USB mouse."
I think it a different problem. In our case touchpad working well before press the enable/ disable switch.. e then the pad still working but the GUI has problems (freeze buttons, etc.)
