Using Windows 8.1, after closing the lid or setting my Asus N750JV laptop to sleep / hibernate, when resuming the touchpad no longer reads multitouch gestures like pinch, zoom etc. It behaves like a regular touchpad.
Switching the touchpad on and off using FN+F9 doesn't help either. Only a full reboot fixes it.
How does one re-initialize / run the gesture driver software?
