Hey I have a Sentelic touchpad that doesn't work very well in Linux, its supposed to be all multi-touch and such, it works all right in MS Windows. I really am not a fan of using Windows though.
The worst thing that it does .. is that it doesn't disable itself when typing, so it will always take focus away. I can disable it with modprobe -r psmouse
but it would be nice to have it do this automatically.
Also if you can think of a workaround to re-enable it automatically that would be great :)
