I was forced to enable swap because it I run out of RAM without swap then 95% of the time my laptop hard reboots. Adding a ton of swap fixed it.

My next issue is that sometimes it just hard-freezes. Zero warning, under no load, I can't even move the mouse. Linux on the desktop!

I added a userland OOM and now my browsers or slack dissapears and I'm confused for 5-10 secunds every time. sometimes my editor or one of the lsp servers.

cspell also leaks like crazy

Oh how do I do this? Can you choose what processes it kills first even if they're not the worst offenders?

I had this issue with System 76 with Ubuntu (for work). It was infuriating.

I've had Fedora lock up on me a few times over the years, eventually some update fixes something pretty quick and it stops doing it. Tbf, I've had windows freeze on me far more all the way from '98 to XP to Vista to 8.1 to 10, I kinda just figured it happens sometimes.

Nah this is like once a week. Windows (post XP) crashes on me maybe once a year. It's much more stable than desktop Linux in my experience.

It's been maybe once a year with Fedora (except that time it was three days before the update that fixed whatever the issue was, but then it was like three times and I pretty much count it as the same "incident"). Wish I could help, but short of knowing why all I have is "well that sucks bro." Maybe looking into your logs when it happens will help identify a specific problem that can be fixed, if you care to do so. If you like windows though just stick to windows, whatever.

You may want to consider fixing the system cache value.

I use lower values than Linus suggested.

What hardware did you use ?

[–] FizzyOrange@programming.dev 1 points 2 months ago

Some Dell/Intel business laptop. Nothing exotic.
