How can I investigate the cause of total hang? Is there some information that I should pay attention to in order to get some hint?

[Drew Einhorn]

I'm starting a brand new thread,
I'm using the same title as the old.

Although the underlying cause is different, I do have the same problem.

I'm using my computer.
I walk away come back later.
It is now unresponsive, and at first, the only way I could recover was by
cycling power and restarting.

By taking the advice in the prior thread I have made some progress, but not
yet solved the problem.

I'm sorry at this point the email escaped before I was ready to send it.
I replied to my own message and added more information.
I'll restart at this point.

I see a message that indicates the screen is locked and that in a few
seconds I will see an unlock dialog.
After a few seconds, the screen blanks and I am locked up again.
I looked around in /var/log and did not find anything useful.

How can I further troubleshoot this problem?
How do I get graphics up and running again?
How do I prevent this from happening?

At least now, I can restart the system more gracefully after logging in to
tty2 without turning off the power.

Where are we going?
And, why am I in this handbasket?
