Hi Ian,
it would probably be a valid approach except for these facts:

- The problem ONLY appears when I have reached the login screen and stay there,
like after a reboot and noone touches the system

- The time interval between the reboots is fairly constant as long as the system
just sits there (384 +/- 2 seconds)

- If I stay on the login screen and move the mouse a bit, the interval enlarges,
but only for that specific "run"

- If I have been running the GUI for say 24+ hours (no reboots then even while I
am sleeping over night) and then log out and walk away when it sits on the login
screen, then 6 min later it reboots. It seems like the boot takes about 20
seconds so that gets us up to 384 seconds again, (this is not accurately timed)

BIOS
----
I rebooted and entered the BIOS (F10) key and found a "Power Management Options"
page where I Unchecked "Runtime Power Management" and "Extend Idle Power States"

Then I rebooted and let it stay on the login screen.
Reboots every 384 seconds again. So no change.

I will probably stop this futile hunt now and install (maybe as dual boot)
Ubuntu-Mate and see if that fares better.
It has an OK desktp out of the box so I do not have to fix selectable desktop
managers to log in to.
