Which Arch Linux Kernel Should I Use!

There's a bunch of kernels available in the standard repos and the AUR for arch linux but what do they all do and which one should you use.

for anyone using any kernel aside from the non-stable, be sure to read the wiki! Some things, like nvidia-dkms, may require the kernel specific headers! each package should have the following naming style: kernel-headers. For example: linux-zen is the kernel, while linux-zen-headers is the proper header package.

I've been using the Zen kernel for around a year now on my desktop and could never go back for one single reason: when out of RAM and in need of using swap, my system behaves perfectly fine on the Zen kernel, I barely feel it. The same thing was absolutely horrible on both the standard and the LTS kernel: when my system started swapping, it became unresponsive, with my mouse lagging for seconds to minutes in the worst cases. I looked up why the standard kernel was behaving the way it was, and it turns out that it's because it's optimized for server usage and high throughput.
TLDR: when RAM is full and in need of using swap, my system is just as responsive as otherwise when using the Zen kernel, but on the standard kernels my systems starts to lag and becomes unusable.

Also, the LTS kernel gets a lot of backported code from the newer releases. But only code that doesn’t change the ABI or the behavior of features that other software relies on.

My personal experience with the zen kernel has been wonderful. Even with my 9900k and 2080 it is basically required on windows only AAA titles(ie cyberpunk 2077, gta V, etc). Without it these games jump from 20-40 fps at 4k to a stable 60 fps at 4k. Also if you run nvidia drivers you will need to replace them with the nvidia-dkms package.

Been using LTS for months and I love it. It seems to use less RAM and my laptop seems to be cooler too

[ayushmaanaggarwal]

You might need to search for and use a hardware specific kernel sometimes. The Microsoft Surface lineup, especially the touchscreen and pen options wouldn't work in most cases without using the surface-linux kernel.

[ZephyrCheez]

The one I use is less known, but it's called the xanmod kernel with the task type scheduler

I'm using stable 5.14.10-1 right now...
That Manjaro Kernel switcher is quite handy.

I have used different kernels for Arch Linux, but I didn't get any massive performance difference. So I switched back to the main (stable) Arch Linux kernel.

[maxarendorff]

I've been running the LTS kernel for years now. It's just a more stable and reliable experience and I don't need any of the newer features of the latest kernel or support for brand new hardware.

[systemthirtytwo]

Are you guys mind readers? Every day when i think of something to do with my Arch install, one of you guys drops a video on it. Like when i had just been thinking of switching display manager to SDDM Dt drops a video on it, when i think of switching kernel you drop a video on it. I'm getting scared!

[LevisRaju]

when I had my ryzen apu on its early days which the kernels out there was not completely supporting it, I learned to compile them myself to include some newly released kernel patches from amd which were not merged to the latest stable releases.

[Nzer]

I've been using linux-amd-znver2 from the AUR for months now, on a Ryzen 4700U laptop, of course. It's newer than the official linux package from core/testing and still stable, never had any problems with it.

[scavanger]

I've been using zen on desktop and laptop for like half the year, it's pretty neato

[DerekWitt]

I run the Xen (not Zen) kernel on my Ubuntu 21.04 server (HP compaq presario from 2008). Works quite stable for my various virtual machines I sometimes fire up from time to time.

I need Waydroid, so I have no choice but installing linux-zen if I don't want to compile the kernel.

[JeoshuaCollins]

The best way to maximize your kernel performance is to find a pre-made kernel that works for your needs, get the source for that, run the xconfig, and select "Native" for your compiler optimizations. Then make the kernel package for your distro and profit.

[nnaaaaaa]

i personally love the debian testing kernel because it's got all the benefits of rolling release without having to deal with the arch linux package maintainer breaking stuff every few months.

[Bagginsess]

If you're familiar with it could you do a video on overclocking CPU/GPU? Would be cool to flex on windows power users 🍿

[paulnoecker]

Funtoo user btw. The aufs kernel is live cd specific. Aufs was recently deprecated by new union file systems in the kernel
