Ubuntu Studio : Liquorix doesn't appear on Grub menu

Soli Deo Gloria · 06-13-2020, 10:23 AM

I installed the Liquorix kernel on Ubuntu Studio 20.10 with the official installation instructions. After the sudo update-grub thing and reboot, it doesn't show at all on the Grub menu. I tried Boot Repair and the Grub customizer, but even there I can only see the Linux low latency kernels. If I check the installed kernels with dpkg --list | grep linux-image, I can see it there :

ii linux-image-5.4.0-26-lowlatency 5.4.0-26.30 amd64 Signed kernel image lowlatency
ii linux-image-5.4.0-33-lowlatency 5.4.0-33.37 amd64 Signed kernel image lowlatency
ii linux-image-5.6.0-18.1-liquorix-amd64 5.6-20ubuntu1~focal amd64 Linux 5.6 for 64-bit PCs
ii linux-image-liquorix-amd64 5.6-20ubuntu1~focal amd64 Linux image for liquorix on 64-bit PCs
ii linux-image-lowlatency 5.4.0.33.38 amd64 lowlatency Linux kernel image

Is it "unsigned"? (Whatever that means?) How do I make Liquorix to appear on the Grub menu in order to boot from it? This is quite frustrating, since I need to test that Kernel to see if I can improve the performance with Kontakt.

Thanks so much in advance.

Is it under a submenu? ("Advanced options" I think.)

I installed it yesterday because of xruns in Bitwig and it appeared directly in Grub using Debian 10. Have you looked at the forum?

The dev is very helpful and answers quick.

I'll write to him during this week. At least, I want to try it once to see if it makes any significant difference in my setup....

did you contact the dev? I tried installing this kernel in Ubuntu Studio 20.04 and it also won't show up in Grub.

In the instructions you've read - did it say "sudo update-grub" ?

Seems to me that that's whats missing.

I did update the grub many times, but it never showed up... Anyway, I finally moved to Manjaro, and its stock kernel seems to be much better for realtime tasks than even Ubuntu's lowlatency one (mainly due to being the 5.10 version, which includes some substantial improvements).
