Mouse freezes on return from sleep

view story

http://forums.fedoraforum.org – FC18, KDE spin, Lenovo Thinkpad E520, all current patches. Using embedded mouse-pad, no external mouse. Sometimes, but not always, after returning from a time-out sleep, the mouse cursor is frozen. The keyboard works normally. I can alt-tab between windows, and since I normally keep a Konsole window open, I can issue a reboot from there. 1) Any idea what causes this? 2) Is there a way to restore the mouse without having to restart anything? 3) Is there a way to restart X without having to reboot? CTRL-ALT-BACKSPACE does not work as it did years ago. Thanks, JimR (HowTos)
