What model of TouchPad is it? When it is used in Windows, is there a specific driver loaded, or does it rely on a generic PS/2 mouse driver? It is possible that the TouchPad is a Synaptics TouchPad with the DisGest (Disable Gestures) bit set. In this case, the TouchPad gestures will not work when a standard mouse driver is used. You can read more about this in the "Synaptics TouchPad Interfacing Guide" from www.synaptics.com Some vendors requested that the gestures should be disabled by default. Some vendors install a PS/2 command sequence in the BIOS which turns gestures off every time the machine boots. In the second case there may be a BIOS option to change this behaviour. In either case it ought to be possible to send the PS/2 command sequence to change the DisGest bit to zero. In Windows, when the Synaptics driver is in use all gesture processing is done in the driver, so the DisGest bit is ignored. A Control Panel setting allows the tapping gesture to be turned on or off, which merely changes the behaviour of the driver. Synaptics does not supply a Linux driver, so the available features/settings may be different or not present depending on what exactly is talking to your TouchPad. If it's not Synaptics, then this discussion is most likely not useful. HTH Andy
