Since upgrading to Mountain Lion, upon waking from sleep, my Trackpad's gestures, (ie. swiping spaces by dragging 3 fingers across trackpad), disappears. No trackpad gestures work, (ie pinch to zoom, etc.)
After some time, Mountain Lion appears to sleep without reason momentarily, (less than a second) and gestures then return.
Or a restart will restore gestures.
iMac, Mac OS X (10.7.2)
Resetting the SMC worked liked a charm. I was having the same issue with the TrackPad and my Early 2009 Intel iMac. After sleep mode, the extended functions of the TrackPad stopped working. Reset the SMC and then let the iMac sleep for about 2 hrs, came back and it worked as its supposed to.
This appears to have worked. Thanks.
Spoke too soon.
The SMC reset did NOT resolve my issue. It appears to be inconsistent, as initially I did not lose gestures after the SMC reset, but now I am again.

this may be an application you have installed or your settings... make sure you have tap tp click on. creat a new user and see if your issue persists.
Trackpad settings are default. As the issue only began after upgrading to Mountain Lion, I don't know how I can track an errant application that did not cause an issue with Lion but does with Mountain Lion.
But thanks for the help.
You can start by creating a new user in system preferences>users and groups.
sign into a new user and you are virtually on a clean installation of ML. See if your issue happends in this setting.
You may need to perform a PRAM reset

if that doesn't fix it, and a new user does not show the issue, then it is certainly a third party app conflicting with the OS.
if it still happens in a new user, you may need to reinstall ML from the recovery partition>
To get to the recovery partition restart your computer, hold CMD+R down when you hear the boot up chime. Open Disk Utility first (verify your boot disk and repair if needed) and then close it and reinstall ML.
I had this problem but I found it was the settings that changed when mountain lion was installed.
Mountain lion changed my three finger gestures to four finger gestures when swiping between full screen apps.
I found there were extra settings. Apparently when installing mountain lion my three finger gestures were changed to four finger gestures.
It seems that gestures reappear every other time or so my Mac wakes up, as far as I can tell.
Weird.
I have called to apple support and did all the resets they instructed me to do and it worked for a week or so and now it is doing the exact same thing, computer wakes up from sleep and the two finger gesture is the only thing that will work. very annoying. I have a case number and was about to call back in but found this is a known issue and dont want to waste my time calling. suggestions?
The issue seems to be connected to screensaver, not just sleep.
If I've lost trackpad gestures upon waking from sleep and then screensaver kicks in, coming out of screensaver, gestures is back.
Might be a workaround, instead of restarting.
The work around is turning off your screensaver. I think the glitch is in the screensaver. Once I turned it off, no more problems.
There are a couple of other discussions on this same topic - and yes the issue is related to both screensaver and sleep. It seems to occur when the computer goes to sleep while the screensaver is active.
Two suggestions that help (but don't fix) the problem (see https://discussions.apple.com/thread/4180109 ):
1. Set a "hot corner" to "start screen saver" (it's in your "Desktop and Screen Saver" system preferences). Whenever this happens, just move your mouse to that corner for a moment, and gestures will start working again.
2. Use terminal to type killall "Dock" whenever the issue occurs.
Since I first posted this solution it never happened again.
