Good idea, stupid name.

Excellent for causing FUD.

No, this will not increase the amount of kernel panics you see. It just makes them more informational to the average person. Technical folks can disable it, non-technical folks won’t know how to enable it, so on by default it is.


I hope this isn’t going to be the default. I know, the average granny might prefer to have a BSOD with a QR code, but I think a lot of the people who are more tech-savvy, like me, would prefer to see log messages when booting because then you could see which service failed and why or why it’s all of a sudden taking so long to boot. That’s also why I choose not to have a splash screen when booting.

Anyways, this BSOD thing doesn’t apply to me because I use Gentoo with OpenRC.

I’m honestly fine if this is the default for beginner distros, as long as it’s easy to disable and there is still a way to get to the logs

Just let me hit ESC and see the panic.


Came here to say this. Let them toggle the logs or the QR code.


Phantastic! Can we have ads in the task bar next?

I just wish they would use another name for it, it’s linux here no need to copy windows slang! Or use another color! (I hope they’ll update it to make it a customizable color)


Fun fact: The Windows BSOD colour was as easy as adding a couple of lines to a .INI file for a long time. Then, as they tend to do, they made it more difficult, but it was still possible. Third party tools were written to do the work.

Very recent MS Windows I have no idea about. My search-fu is failing me.

Anyway, my point is that the "two lines in a config file" method would be nice.

Knowing systemd though, it'll be "send some kind of message into a /proc pseudo-file", or a sub-sub-sub-command of one of the many systemd* commands which ultimately does the same thing.

I love this! Not only for the comedic value, but throwing kernel oopses on-screen when they can’t be easily captured when unprepared would be of great help in solving system problems. Unlike the cryptic messages Windows displays, Linux kernel messages are quite useful.


Isn’t this the default behavior of all(?) modern *nix init? Maybe not SysV, i don’t know.

avidamoeba, avatar

Is it? I’ve been on Debian/Ubuntu since 2005 and I’ve never seen anything on-screen whenever I’ve gotten a kernel oops.


They use Systemd, so there.


I want it with Elon’s face in the backgrund, so that I can throw some darts at it!


Is it April 1st already?

Holzkohlen, avatar

At least make it pink or smth

ikidd, avatar

Maybe it can be the “brown screen of death”. Kinda like poop.


PSoD is already used by VMware ESXi. And Windows Insider builds, I think.

Maybe green?



Piss Screen of Death?

edit: oh nvm, I mistakenly thought this was in reply to the suggestion for dark yellow.

uriel238, avatar

Maybe a customizable setting? Black screen with red border and a looping kittens video?


Green is Windows Insider builds


Dark yellow?

  • Hibernation into swap files backed by Btrfs are now supported.

So, with btrfs on ssd, is there any use case for a swap partition?


Use case is not having enough RAM?


I think what they mean is that you can just make a swap FILE instead, which you can grow and shrink as needed. No need to mess with partitioning.

Infiltrated_ad8271 avatar

Yep. In fact my comment seemed so clear to me that I assumed it was some kind of joke, but looking at the votes, maybe swapfiles aren't as well known as I thought.


Swap is not “disk RAM”.

falsem, (edited )

What would you describe it as? With virtual memory it pretty much functions that way, no?


I’m not sure what that post is meant to show, if swap isn’t “disk RAM”. That post even concludes:

Swap […] provides another, slower source of memory […]


Um, you really need to read the entire phrase and not pick out only what you want from it. 😃

Swap can make a system slower to OOM kill, since it provides another, slower source of memory to thrash on in out of memory situations

It means that if you try to use it as a source of memory, when you run out of actual RAM it will make your system almost completely unresponsive due to disk thrash, instead of allowing the kernel to just kill the process that’s eating your RAM. So you’ll just end up hard-booting system.


Yes, and that’s a good thing if you don’t want it to start killing processes. You have that extra time/space to deal with the out-of-memory condition yourself.

Or you can ignore that condition and continue using the system in a degraded state, with swap as “disk RAM”.


Like I said, the system will be almost completely unresponsive due to disk access being several orders of magnitude lower than RAM and allocation thrashing… you won’t be able to do much, the mouse, keyboard and display will react extremely slowly. There may be situations where you’d prefer this to an OOM kill, for example if you’re running a test or experiment where you’d rather have it finish even if it takes a very long time rather than lose the data. But if you’re a regular desktop user or server admin you’ll probably just reboot.

Do you mean that you don’t have to find the LBA of the extents of your swap file, and put that into a kernel argument anymore?

Cuz that is a nasty, skanky hack.

Infiltrated_ad8271 avatar

I've never heard of that, it's beyond me. So it's an increased risk when tweaking the kernel? As an average home user it's all right?

rotopenguin, avatar

I don’t think it’s going to do a whole lot of good when the whole KMS/DRM falls over.

(okay I haven’t had that for a few months now. But i am still traumatized)


Seems like some kind of sacrilege.


i totally understand if they named it bsod just for the meme, it’s funny also they could make an option to change de color :b


They could have gone with the “Red Screen of Wrath” or something.


Mauve Screen of Suffering


Lilac of Log Level 1


I’m giving you bonus points for the alliteration.


That almost sounds soothing.


Tosca Screen of Wailing


Crimson Screen of Grief


Black Screen of Meditation


That one I already have.


The thought of someone’s Linux install failing catastrophically, displaying a “MSoS”, then the user switching back to the is MS OS because of it is funny to me.

Thorned_Rose avatar

Back about two decades when I was using Windows and it was till easily customisable, I changed the bsod colour to red for funsies. Windows being Windows crashed and went to my red screen of death - my ex's cousin saw it and thought it was something really really bad, "Wow, a red screen, never seen that before. Must be even worse than blue". No mate, I just customise the shit out of anything I touch 😅


Fuchsia Screen of Disappointment


Agreed, bsod is precisely what I’ve been running from with Linux.


Correct me if I’m wrong but isn’t this basically just better error reporting? It’s not like it’s gonna crash more often, it will just actually show log info if something catastrophic happens.


No, there is a random crash every six hours now to increase familiarity.


Unfortunately this only affects boot messages, not normal system operation, for that you still get core dumps and kernel panics / oops

ikidd, avatar

A BSOD that gave you a clue about why it happened would be a welcome change.


that’s the goal, they also gonna implement the QR code, but not like the crappy of QR code on windows(that send you to a suppirt page with a dozen of possible sulution, where nothing work), the qr code is going translate to the kernel panic message, i liked, i can scan the qr code and search the error on my cell


Some Highlights:

  • A new component “systemd-bsod” has been added to show logged error messages full-screen if they have a “LOG_EMERG” log level. This is intended as a tool for displaying emergency log messages full-screen on boot failures. Yes, BSOD in this case short for “Blue Screen of Death”. This was worked on as part of Outreachy 2023. The systemd-bsod will also display a QR code for getting more information on the error causing the boot failure.
  • Hibernation into swap files backed by Btrfs are now supported.
  • Support for split-usr has been removed.

Actually looking forward to the btrfs swapfile hibernation; I have tried setting it up on my machine before but the documentation was never clear on whether it would work (or why mine wasn’t).
