I never had this problem until upgrading to 8.10, and SO FAR, it has only happened when I have dual monitors running. When I run dual monitors, I'm running Xinerama. When I go with both, it's happening a few times per day. When go with just the lappy screen, it has not occurred yet.
One other difference, when I use only one monitor, I don't have any mouse attached - only the touchpad.
Only resetting X server fixes it, that I can find.
