I basically don't ever shut off the machine, unless forced to. Sometimes, after
bringing the machine up out of sleep mode, the mouse-pointer is gone.
You can get to a command input via ALT-F2, and there must
be a command that initializes the mouse pointer. What is it? (Otherwise, the
only cure I know is to shut down and reboot from cold start.) PCLOS 2010.
The mouse is a Kensington usb trackball.
If there is a _particular_ update that fixes this, I will try it, but please do not
suggest I upgrade the whole system or install 2010.07 from scratch. I have
had far too much grief along that highway already, and I will not do it again.
The system basically works, and I would like to be able to use it, not mess
around trying to get it back running. If I ever install a later version from
scratch, it will be on a new machine. Meanwhile, the problem is livable,
especially if I can run a "fix" command.
(This is not the machine that I could not upgrade--that's a different animal
that I await assistance on.)
