Thanks Akkana

Yeah, can't check much when frozen. I've looked at dmesg but too much in there that I don't understand. I'll come running for help if this gets worse. It's usually only every couple of days. I do put the machine to sleep a lot. Maybe I need to shut down daily or some such,

This. I've seen a lot of discussion about swap, but if there was any
evidence that swap was the problem, I missed it. If adding swap is
going to be this hard, maybe put the effort instead into diagnosing
why the system is freezing?

For instance, do you know if it's X or the kernel that's freezing?
It would be interesting to try to ssh in from another machine,
to see if maybe the machine is up but X is locked.

Diagnosing a freeze isn't all that easy, because of course if the
kernel is hung, then the system has no way to note what went wrong.
But sometimes you can find out what was happening just before it
froze. Here's a Google search that gives some starting points:
