Hi Pascal, Since it seems to all be working for me, I hesitate to mess with it.
I still have two issues, neither of which are too serious (or else maybe I still dont understand them). 1) The touch pad, under synaptic, is supposed to scroll when you touch it with two fingers. With your previous changes, the synaptic driver has been removed, as verified by /var/log/system, (as intended), so the two-finger scroll is not working at all. But the touch pad does respond to the one finger (thumb) touch, and works just like a second mouse input. 2) Every now and then, as I'm typing, my thumb slightly touches the touchpad causing the focus to move to where-ever the mouse pointer is sitting at that moment (i.e., some random position). Once my thumb, or more likely my palm, touches the track pad, anything I'm typiing moves to the pointer (mouse) random location, so my typing focus moves away from where the cursor is. Note I'm distinguishing the typing location (cursor) from the mouse pointer location, as they are distinct pointers. Having the text-cursor (pointer at which your typing) switch to the mouse pointer (pointer that moves with the mouse) location, while your typing, is a very serious problem, as you typing moves to that location. "Bandaid workaround" So my workaround, and it is quite effective is to place two large bandaids on the left and right side of the touchpad, to mask off about 1 inch on each side. Once I did this, the touch pad became useful again. It is simply too large, so large, that I cannot avoid touching it as I type. Note, I'm a full 10 finger typer, not a two finger "pecker." For a small move of the mouse pointer, I can use the trackpad via thumb. For large movements, that's too inefficient, so I use the red eraser-head (track point mouse). The orginal problem was that the mouse would randomly stick on.
