Snakeoil 1.4.0 (High End)

[fliptoback]

Is there a drag n drop experimental real-time kernel for 1.4.0?

No drag and drop.  If you are running the Amd version you can join Ubuntu Pro and install, enable the real time kennel.

You can then switch RT kernels using SnakeOil/ Kernel.

P/s bug in Pi version, cannot switch

Hi there, I am watching this realtime kernel question with interest. I have installed Snakeoil High End 1.4.0 on Ubuntu 24.04.01 LTS and would like to also use the realtime kernel.

I have an ubuntu pro subscription and a token.

I have done the "sudo pro attach token###" command and also the "pro enable realttime-kernel" command.

My console looks like this:

root@songbird:~#  pro status
SERVICE          ENTITLED  STATUS       DESCRIPTION
anbox-cloud      yes       disabled     Scalable Android in the cloud
esm-apps         yes       enabled      Expanded Security Maintenance for Applications
esm-infra        yes       enabled      Expanded Security Maintenance for Infrastructure
landscape        yes       disabled     Management and administration tool for Ubuntu
livepatch        yes       disabled     Current kernel is not covered by livepatch
realtime-kernel* yes       enabled      Ubuntu kernel with PREEMPT_RT patches integrated

But that is where I am stuck. How do I proceed next?

I tried to install the kernel and it return this:

root@songbird:~# sudo apt install linux-image-rt-amd64 linux-headers-rt-amd64
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package linux-image-rt-amd64
E: Unable to locate package linux-headers-rt-amd64

I tried to apt update but it still fail.

Please point me in the right direction? Thanks!

Edit: I am using Snakeoil on a HP T630 thin client - all works as it is - just wanting to upgrade to the Real time kernel.

are u looking for this？

Yes I was, but my snakeoil does not have this menu structure. I attached my screenshot below for reference.






What should I do?

I didn't see your attachment.  And, did you finish the activation?

Ahh I see. I have to activate first. okay. I will do that.

sorry for the newbie question. Have been using snakeoil so a few years but I am still not too familiar with the software.

Thanks for your help. I activated the realtime kernel successfully. Havent tried to play back yet but will report back.

You're welcome, enjoy.

is there a specific variant of the RT kernal we should be using?    or just the generic one it suggests on activation?

Use generic for X86 or raspi for Pi.  There are further tweaks that hopefully may come in 1.4.2 ?

So Ubuntu 24.04 server loaded onto a MicroSD card and inserted into unpowered Raspberry Pi, 

BTW, later revisions of Pi 4 and all of Pi 5 are capable of directly booting the OS from a SSD or NVMe now.

A worthy upgrade to switch from MicroSD to a faster solid state media.. And also the rabbit hole of "does SSD sound better than MicroSD"? It certainly boots up faster though.

Yet to really listen critically though, will have to find a day to do a proper listening session some day.

I just found that SO 1.4.0 in Pi5 can't run the latency test, neither from the webui nor cli.  Is that normal?

I think this was a problem in 1.3?  And it is on list of issues to be fixed soon..
