Blue Screen Of Death on freshly-installed system

Yes. Forcing a hard shutdown (or reset) is never a safe option. Instead, REISUB/REISUO would have been a better option.

I appreciate the suggestion. I suppose I should have known this - I’ve been using Linux a fairly long time.

Just to be clear, the tutorial says:

How to invoke the REISUB procedure?
First we have to unlock the SysRq key so:

• Execute echo kernel.sysrq=1 | sudo tee --append /etc/sysctl.d/99-sysctl.conf

So, if I understand correctly, this would seem to require advance preparation. It wouldn’t be practical to follow the above step in a GUI environment when the screen has gone blank, right?

So in order to use REISUB, I would have had to anticipate a freeze and execute the above before anything else on a freshly installed system?

Or am I misunderstanding something?
