Can someone please write a "HowTo for installing a Liquorix Kernel"?
I as well as @lilith did not make it despite the instructions on the

<EDIT>The instructions on their HP are correct. See the Install guide on their HP:</EDIT>

the better distro kernel

Liquorix Kernel

Liquorix is a distro kernel replacement built using the best configuration and kernel sources for desktop, multimedia, and gaming workloads.
so far.
Thanks!

What more is there to say beyond the instructions on the website?

I tried to install it a few months ago, and couldn't get my system to boot. So I reverted back to lowlatency.

So that makes at least 3 of us who struggled with it, although I am probably the least of the three when it comes to computing prowess. :)

I'm on Debian 10 and there was an issue with the keys. I haven't give it another trial yet. The Dev changed the installation command. As khz screwed his system last year by installing the kernel I'm a bit cautious.
I opened a thread in the tech patterns forum also: https://techpatterns.com/forums/about2806.html

Oh I'm not the professional about Linux either.
A lot of c/p I simply, also with the Liquorix Kernel install from their HP which was more than unsuccessful with me.
Otherwise I write everything meticulously in my note (signature) because I forget much faster than to find the right solution.

<EDIT>I had tried to install the Liquorix kernel back then with Debian-9 stretch following the instructions on their HP. System was no longer updatable after that. Probably some mistake of mine.</EDIT>

I installed it on Ubuntu and it worked a treat. The system felt snappier, and I could use the Nvidia hardware acceleration, which was not possible with the normal low-latency kernel.

I have installed it under Debian 10 by following the instructions on the website. No issues so far and like openmastering said, it feels snappier and buttery smooth. hands down the best experience I've had with Jack and linux.

Ok, I have another beer and give it a try.
Cause I'm still getting xruns in Bitwig,which does not happen with Reaper or Renoise.

@lad @Openmastering Ah that reassures me that it is to be installed according to HP instructions.

I guess I made a mistake. Although I'm not the only one.

That worked. What do I have to install out of these:
Image

especially what's the difference between: linux-image-5.6.0-18.1-liquorix-amd64 and linux-image-liquorix-amd64 ?

Code: Select all

sudo apt-get install linux-image-liquorix-amd64 linux-headers-liquorix-amd64
You only need to install the packages ^

These are so called meta packages, meaning they will always install the latest version when there are updates. Liquorix kernel updates frequently aka rolling release.

Should I also enable the threadirqs option again for this kernel?

It's a PREEMPT Kernel: Linux marco 5.6.0-18.1-liquorix-amd64 #1 ZEN SMP PREEMPT liquorix 5.6-20.1~buster (2020-06-10) x86_64 GNU/Linux

But the realtimeconfigscript still complains at this point:

I have done it but I am not sure if it is necessary :?: Good question...
