When Ctrl-Alt-Del fails on Linux: Fix a Frozen System with the Magic SysRq Keys (via FOSSwire)

Posted by jpluimers on 2024/04/26

Ctrl-Alt-Del will not safely reboot all systems under all circumstances.

If you run Linux, your keyboard has a magic RysRq key (sometimes not marked, but its the same key as the Print-Scrn key) and the Linux kernel is still running not all is lost.

Due to link rot, the archived links are the most recent that have all the comments for [Wayback/Archive] Fix a Frozen System with the Magic SysRq Keys | FOSSwire which amend

You finally got your Linux environment to crash. Ctrl+Alt+Backspace does nothing, nor do the F-keys. You know you shouldn’t have installed that bad driver, but you did it anyway.
So you reach for the power button.
Stop.
Mashing in the power button to reboot could cause a problem if your hard drive is still being written to, and usually causes more problems than it solves. The Linux kernel includes a secret method of restarting your PC should it ever stop doing its job.
  1. Hold down the Alt and SysRq (Print Screen) keys.
  2. While holding those down, type the following in order. Nothing will appear to happen until the last letter is pressed: REISUB
  3. Watch your computer reboot magically.

This 2007 comment makes it easier to remember: REISUB is the reverse of BUSIER:

R E I S U B – is just the word busier in reverse.

Some notes on Input Director and alternatives: what about multiple platforms and mixing local plus remote access?

Posted by jpluimers on 2022/07/29

More than 10 years ago, I wrote about 7 screens; 3 computers; 1 keyboard/mouse to direct them all: Input Director and started with

At home, I have 7 screens on 3 computers on the same desk. That sounds like a clutter, but all these keyboards and mice hooked up to them add even more clutter. Until I found out about Input Direct…

In the mean time, I’ve mainly used a Mac with MacOS as a front-end to virtually logon to remote machines using both the internal display and one or two external monitors.

Especially when doing video (think Covid-19 and especially on-line meetings!) in addition to software development work, this is far from ideal.

So here are some things on my list of potential enhancements to this situation:

How to Configure Stack Overflow The Key Macropad? | Drop

Posted by jpluimers on 2022/07/20

In the past I joked about a Copy/Paste keyboard for Stack Overflow, and even Stack Overflow had an April 1st joke about it early 2021 (see below). Boy  was I surprised by now it actually has existed for more than half a year!

Thanks [Archive.is] Matthijs ter Woord for pointing my attention to this.

Drop actually has some nice keyboards. Now I wish they made an UltraNav one. Their selection is at [Wayback/Archive.is] Mechanical Keyboards | Recommended Products | Drop.

The process where The Key became reality: [Wayback/Archive.is] Can I actually buy a copy-paste keyboard like the Stack Overflow April Fool’s “The Key”? – Meta Stack Overflow

First/Last-Tab: Ctrl-1/9 (or Command-1/9): Switch Between Tabs in Any Browser Using Shortcut Keys

Posted by jpluimers on 2021/12/10

Only recently, I learned this works on just about any web-browser:

  • Ctrl-9 (macOS: Command-9) goes to LAST tab
  • Ctrl-1 (macOS: Command-1) goes go FIRST tab

Via: [WayBack] Switch Between Tabs in Any Browser Using Shortcut Keys

For those keyboard ninjas who hate using the mouse, switching between tabs in your browser window is essential since most people probably have a bunch of tabs open at once. […]

If you want to go to a specific tab, you can press CTRL + N, where N is a number between 1 and 8. Unfortunately, you can’t go past 8, so if you have more than eight tabs, you’ll have to use a different keyboard shortcut or just click on it. CTRL + 9 will take you to the last tab, even if there are more than 8!

Yet again, GitHub violates the Web Content Accessibility Guidelines by stealing a key: not it is the dot (.)

Posted by jpluimers on 2021/08/17

More sites seem to have a tendency of stealing keyboard shortcuts and violating the WCGA (Web Content Accessibility Guidelines), especially the (lowest!) conformance level A in [Wayback] WCAG version 2.1, section Success Criterion 2.1.4 Character Key Shortcuts

If a keyboard shortcut is implemented in content using only letter (including upper- and lower-case letters), punctuation, number, or symbol characters, then at least one of the following is true:

1. Turn off
mechanism is available to turn the shortcut off;
2. Remap
A mechanism is available to remap the shortcut to use one or more non-printable keyboard characters (e.g. Ctrl, Alt, etc);
3. Active only on focus
The keyboard shortcut for a user interface component is only active when that component has focus.

Mind you, I’m a keyboard person, there is even a: Keyboards and Keyboard Shortcuts category, but they always need to be configurable, anything else is a sin.

And GitHub did it again: [Archive.is] GitHub on Twitter: “🤫 New shortcut: Press . on any GitHub repo.… “.

So I’m totally with these:

Now they have started to steal the dot (.) keyboard to (in-place, with a fully new URL and no indication how to easily go back) start Visual Studio Code in the current repository.

Going back, though not documented, actually takes between one and three “back” movements in your web-browser history: utterly ridiculous for a key one can accidentally hit.

This behaviour violates all three above sub-criterions:

  1. it cannot be turned off
  2. there is no way to remap it
  3. it is almost always activated (unless there a text input – like “search” or “goto file” – has focus)

This is a very bad way to cope with accessibility, especially as conformance level A is yet again violated.

[Wayback] WCAG 2.1: section 5.2.1 Conformance Level:

One of the following levels of conformance is met in full.

  • For Level A conformance (the minimum level of conformance), the Web page satisfies all the Level A Success Criteria, or a conforming alternate version is provided.
  • For Level AA conformance, the Web page satisfies all the Level A and Level AA Success Criteria, or a Level AA conforming alternate version is provided.
  • For Level AAA conformance, the Web page satisfies all the Level A, Level AA and Level AAA Success Criteria, or a Level AAA conforming alternate version is provided.

To me another cardinal sin is that they stole Ctrl-F / Command-F (depending if you use non-MacOS or MacOS) from the web browser. So now it does not find it in the full page, but only in the currently selected file. (You guessed it, I’m with [Archive.is] KewlCat on Twitter: “I hate it when they intercept “/” and even [Ctrl]-F… “ too)

More of those conformance violation sins are at [Wayback] Keyboard shortcuts – GitHub Docs.

It isn’t hard to prevent this kind of thinking: it’s a mind set as described by [Archive.is] Patrick Joannisse on Twitter: “I don’t know if you are expecting a real answer but here goes: it starts with the mindset. In my training they had us wear goggles to block our vision and made us use a screen reader for a while. We met people with disabilities and they would show us how they work.… “

If you still like it and want to know how it works

Operant Conditioning by Software Bugs – Embedded in Academia

Posted by jpluimers on 2020/07/21

Good to remember both these:

[WayBack] Operant Conditioning by Software Bugs – Embedded in Academia which means when using a system, you subconsciously start behaving around it’s issues. This also happens when you the software you wrote the software for such a system: you hardly test the things that you broke.

The magic SysReq key on Linux systems running on PC-hardware allows you to sync/mount read-only/shutdown a system by keyboard (and many more options – see the Wikipedia list below). Do not forget to enable this as it is disabled by default. And remember that many laptops forego the SysReq key (as do Mac systems).

The order while holding Alt-SysReq down is S,U,B…

Remapping a mac keyboard for windows user In my quest to make this macbook air into a usable machine: Karabiner-Elements

Posted by jpluimers on 2020/07/10

I am still a bit ambivalent on remapping keys on a keyboard, mainly because of two reasons:

  • Without remapping, tools used for virtualisation, remote access and shells already get it wrong every now and then. Finding causes is already tough, so adding more degrees of freedom complicates this more.
  • Switching systems or assisting people without the tools can be cumbersome. I vividly remember the really hard times when I had switched from Windows Explorer to Windows Commander (now Total Commander) and could not use it on a sequence of contracting jobs.

Just in case I am going to use it:
