Hello,

For me a reboot- that is a complete shutdown and cold boot with no hibernate, will clear the problem, but then if I allow the machine to sleep or hibernate again, the problem will return.

No problems in the device man, nothing in the troubleshooter, however, the synaptics software is not recognising the device as a touchpad and complains about the touchpad not being installed.

Having a slight suspicion here - I used taskman to locate, and kill any synaptics pointing device processes, and then started the synaptic software again - first by starting "synaptics info", then the "synaptics settings". This seems to work which indicates there is some kind of unclean state in the synaptics pointing device helper that is causing this. The settings version I have says "Synaptics Touchpad 7.5". Looking on the net - synaptics do not offer software to end users - it is down to the OEM's (read your laptop brand) to integrate and update them.

However - my machine is a Samsung laptop, and there own SW Update tool does show a touchpad update - so I'll see if that remedies the problem - if not - at least killing that process and forcing it to start gives me a workaround.

For the windows Gurus - does the touchpad have some kind of unique device instance (not model) ID in the HAL somewhere, and is this possibly not retained (ie given a new one) between sleep/starting states?

Hi Everyone

I got back the Gestures !!!
I did a System Restore and got back the pinch to zoom and two finger scrolling gestures.

You can either do a System Restore or a Registry Restore (If you have a back up) to a time before the gestures stopped working.

I had the same problem and I finnally fixed it!

go to control panel

click hardware and sound,

click mouse,

select device settings tab,

and click reset devices.

I had the exact same problem in my samsung laptop , It happened because I accidently unistalled synaptics pointer driver.

just type your model ID in google and I'll direct you to your laptops driver page ,

Download the two drivers for touchpad , one of them will be synaptics pointer driver

This solved my problem !!

good luck.
