After upgrading to Windows 10, after waking the computer from sleep, 3 finger swipe gestures (to minimize all windows or to go to task view), stop working. 3 finger click still brings up Cortana. I'm on a Lenovo Yoga 2 Pro using the Windows 10 19.0.9.5 touchpad drivers. Any help is appreciated!
Edit: This isn't a duplicate of the question linked by Ramhound. That question concerns a touchpad being completely disabled after sleep. In this case, only three finger swipe up doesn't work; everything else is totally fine. The solution is to restart "synaptics touch pad 64 bit enhancements". I don't have access to the laptop in question at the moment, but a simple "taskkill /IM SynTPEnh.exe" will end the process. The process will automatically restart. You might want to put this command in a batch script and schedule it to run on wake up, though I haven't been able to successfully use the Windows event system to do this, and just manually run the script on wake up.
Best Answer
until synaptics(the touchpad manufacturer) comes with a fix we had to manually restart the synaptics services after resuming from sleep
start the task manager
look for "synaptics touch pad 64 bit enhancements"
click on it
then click on the "end task" button
by now two finger scrolling shouldn't work don't worry
go to control panel
then hardware and sound then synaptics
it might ask you to unistall driver click NO
the synaptics options window appears
wait for 3 or for seconds and all gestures will start working
