Not exactly as funny meme as I would like it to be, but I just found out about that feature after having to hold the power button due to a frozen system countless times, and I had to tell someone.

Related and IMO a much better option for Linux desktops:

Early OOM

This is great! Why doesnt distros use this by default???

Just put plasmashell and a few in there and you will have a working oom killer. Finally.

I will install this the first thing tomorrow

Wait... Fedora has this since quite a while, strange.

Because if i'm rendering on blender on my lower end PC with expected freezes but it auto kills the render?

[-] Brickardo@feddit.nl -1 points 1 year ago

Sounds like niche use cases

[-] mexicancartel@lemmy.dbzer0.com 6 points 1 year ago

Not niche there can be times when you want to run something heavy and it auto kills the exact thing you are trying to run. You have a 1gb ram device and it kills everything? Thats undesirable

[-] boredsquirrel@slrpnk.net 1 points 1 year ago

Hm.... the process itself should not take that much RAM. I dont know if normally the OS should assign the max RAM to the program.

But this should not happen and I wonder how "just letting it freeze" works

We do not break userspace in this household young man.

Nohang has some explanations to this.

I.e. kernel devs are ignorant to the issue of oomkiller not working as intended on desktop.

Edit: Lkml is down.

[-] marcos@lemmy.world 2 points 1 year ago

Just decrease your swap space.

Unless you have an unusual system, there's no reason to have several GB of swap.

[-] eager_eagle@lemmy.world 7 points 1 year ago

that won't solve the system unresponsiveness

[-] marcos@lemmy.world 0 points 1 year ago

Have you tried?

Because it does.

[-] eager_eagle@lemmy.world 10 points 1 year ago

yes, even turning swap off entirely doesn't solve it. It doesn't take much to find people reporting a similar experience.

[-] MonkderDritte@feddit.de 1 points 1 year ago* (last edited 1 year ago)

Better enable swap again. Linux expects swap.

[-] vox@sopuli.xyz 2 points 1 year ago

or fiddle with the vm/swappiness value

Wasn't oomd the facebook thing for complicated server setups?

edit: yeah, for large data centers. Imho overengineered for single user desktop sessions. Earlyoom is simple and tiny.

[-] CraigeryTheKid@lemm.ee 17 points 1 year ago

ok... I'll ask.. where the heck is the "sysreq" key on my standard keyboard?

[-] julianh@lemm.ee 8 points 1 year ago

Should be the screenshot key

[-] CraigeryTheKid@lemm.ee 6 points 1 year ago

so it is! and I tested it, of course, with alt-sys-b which instantly rebooted my machine. nice.

[-] CarlosCheddar@lemmy.world 7 points 1 year ago

How come sysreq + f is not on by default? After discovering and enabling it I haven’t had to hard restart due to hangs or crashes.

[-] stepan@lemmy.cafe 10 points 1 year ago

Debian has it by default I think. Arch has it disabled because it might be a security risk if someone had physical access to your computer.

[-] lurch@sh.itjust.works 9 points 1 year ago

those debian daredevils like the thrill of living on the edge

Raising Skinny Elephants Is Utterly Boring ... Or so I've heard.
