Losing mouse pointer in non-Kubuntu KDE system

[Doug]

This is OT for Kubuntu, but you guys are into KDE, so I'll ask, because
I'm more likely to get a quick, usable response here.  (Have tried the
PCLinuxOs forum with no answer.)  This is PCLOS 2010.

The system runs KDE 4.4.5, I believe.  Every so often, I wake the system
up and the mouse pointer is missing, and so far as I know, the mouse
is non-functional.  I can get to a command line with ALT-F2.  Is there
a command that will start the mouse back up, and if so, what is it?
(I have tried /etc/.rcsysinit, but it didn't do anything I could determine.)

Thanx.  --doug
