Hi,I have a IBM ThinkPad R50. It has a synaptics touchpad and an extra trackpoint device. When I use the synaptics driver (found here: http://w1.894.telia.com/~u89404340/touchpad/index.html), the touchpad works with a extra features of a synaptics touchpad, but the trackpoint is not functional.
If I cat /dev/psaux or /dev/input/mice both devices give output. I can use the Trackpoint if I use the standard driver include in X.
