If I remember correctly, the integrated finger fat smear annoying device (usually called "touchpad" in this context) is being represented to the system as a PS/2 mouse (older models) or as a USB mouse (newer models). If you do _not_ load a driver for that device, it should be disabled. You should be able to do this with a partial xorg.conf. It might be possible with the HAL/DBus/ConsoleKit XML conglomerate of doom, but I can't tell you where the setting is, _if_ there is... However, this might cause problems with other pointing devices you might have installed. Especially if the touchpad is represented "in parallel" with the TrackPoint (if your model has one). It's also possible that X picks up an external USB mouse and the trackpad and "connects" it to the same (and only) pointer arrow, so this would lead to disabling _all_ pointing devices which obviously is not what you want. In short: Cut the red wire. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
