This is Hacker Public Radio Episode 4137 for Tuesday 11 June 2024.
|
|
Today's show is entitled, I used Rice of Key Sequence to reboot my Frozen Linux computer.
|
|
It is hosted by Henrik Hemrin and is about three minutes long.
|
|
It carries a clean flag.
|
|
The summary is, a Frozen Linux computer can safely be reboot with the Rice of Key Sequence.
|
|
Welcome to Hacker Public Radio.
|
|
My name is Henrik Hemrin and I am your host today.
|
|
In two earlier episodes I have been talking about DigiCam Photo Management Software.
|
|
I hope to come back to that topic in another episode in the future.
|
|
But not today.
|
|
Because today I want to talk about what happened to me about two weeks ago.
|
|
Maybe it happened because I had used the hibernate state which I rarely use.
|
|
That caused my laptop to behave somewhat strange.
|
|
So I decided to turn it off.
|
|
It was my Lenovo Thinkpad T460P laptop running Linux Mint Debian Edition.
|
|
So I turned it off the normal way with the soft button inside the operating system.
|
|
But instead of power off, I was shown a full terminal screen with a lot of text what it was doing.
|
|
But the laptop never came to the conclusion to turn off.
|
|
I have learned that in those situations, although tempting that on Linux I should not force
|
|
to turn off with a physical mechanical power button.
|
|
I have tried that before on another other Linux laptop and it was not the success rather the opposite.
|
|
What I should do with Linux is to talk with Alex Trudge directly to the central brain or in other words
|
|
call the Linux kernel with help of a system request and by that side step the operating system.
|
|
A system request is done with a sysrq key on the keyboard.
|
|
In this situation, I did the raise-up key sequence with a system request.
|
|
I hold down the system request key together with the alternate ALT key.
|
|
And when still holding them down, I type the letters R, E, I, S, U and B.
|
|
One by one in a very slow pace.
|
|
I take seconds between them.
|
|
Then I release all keys.
|
|
And the machine reboots.
|
|
This was very successful for me and the laptop has since then worked as normal.
|
|
I use a full-size keyboard that has a system request key.
|
|
But not all laptops has such a key anymore.
|
|
However, system requests can be reached also on all or most laptops with some key combination.
|
|
But that key combination varies between manufacturers and models.
|
|
In the show notes I add a link to a how-to-geek article about the raise-up sequence
|
|
as well as to Wikipedia about system request.
|
|
Thank you for listening, take care and goodbye.
