Thanks for the reply Stephen, it's so sporadic that it may go a day or
so then lockup. At first I thought it may have been xscreensaver because
I'd turn the monitor on after being gone for awhile and the screen would
be black however the mouse pointer would move. I turned that off for a
few days however the freeze happened again this time as I was scrolling
down through my feed in Facebook. It's weird because not only would FF
freeze but the whole system even the clock on the top taskbar stopped.
I'll install Cinnamon and see what add-ons I can disable that I can do
without for now. I've been clearing the content cache every so often to
keep it low. I'll let that go and see what happens.
