The Ubuntu Studio team is pleased to announce the release of Ubuntu Studio 24.04.3 LTS. This is a minor release which wraps-up the security and bug fixes into one .iso image, available for download now.
The biggest change is the lowlatency kernel has been officially retired, replaced by the generic Ubuntu kernel. Those that have been using Ubuntu Studio 24.04 and upgraded may have already noticed this change.
With that said, much like Ubuntu Studio 24.10 and higher, the generic kernel includes kernel parameters added upon boot that allow the kernel to act in a lowlatency mode, so you now can enjoy the benefits of the lowlatency kernel while using the generic kernel.
We realize this may come as a shock, but when 24.04 was released, we knew this day would eventually come. However, there is no difference between the lowlatency kernel and the generic kernel with these boot parameters. They are:
preempt=full: Makes the kernel fully preemptiblercu_nocbs=allOffloads Read-Copy Update (RCU) callbacks from all CPUs dedicated to kernel threads, improves real-time performancethreadirqsForces interrupt handlers to run in a threaded context, reducing buffer xruns
These kernel parameters can be found in the files in /etc/defaults/grub.d
