| guide | Canonical's latest Ubuntu LTS release, code-named "Jammy Jellyfish," has been well received by users around the world. There are hundreds of new little features and some not-so-common ones that don't get much attention. Here are five unique features of Ubuntu 22.04 that we think make it an epic release. |
Ubuntu 22.04 Release - Five Unique Features
Optimized for data-driven solutions
Data analysis and processing is at the heart of every business today. To do this, you need a lot of computing power. Ubuntu 22.04 LTS brings out-of-the-box NVIDIA virtual GPU (vGPU) driver support. This means you can take advantage of NVIDIA virtual GPU software, which enables you to use GPU computing power in a virtual machine shared from a physical GPU server. Not only that, but if your business depends on SQL Server, Ubuntu LTS for Azure brings SQL Server for Ubuntu powered by "Micro$oft", providing optimized performance and scalability.
Improved Active Directory integration
Additionally, many enterprises deploy Ubuntu across multiple workstations for users across the enterprise. It is also important to deploy workstation policies to monitor and control user access and various key business controls. Active Directory support for policy-based workstation management (introduced in Ubuntu 20.04) has been further improved in this release. Apart from this, this release also brings ADsys client which helps in remote management of Group Policy, privilege escalation and remote script execution via command line . Active Directory now also supports Setup integration using Advanced Group Policy Objects starting with this release.
Real-time kernel support
Also, an interesting announcement from Canonical in the Ubuntu 22.04 LTS release is the availability of a "real-time" kernel option, which is now in beta. For telecommunications and other industries, time-sensitive work requires low-latency operating systems. So, with this in mind and the vision to penetrate these areas, Ubuntu 22.04 LTS brings a live kernel build with the PREEMPT_RT patch applied. It is available for x86_64 and AArch64 architectures. However, the patch has not yet appeared in the mainline kernel, and it is expected to be optimized soon.
The latest applications, software packages and drivers
In addition to the above changes, this release brings with it an extensive list of package and toolchain upgrades. For example, this version brings a variety of Linux Kernel types according to usage, such as Ubuntu desktop can choose to join Kernel 5.17, while the hardware support Kernel is still 5.15. Not only that, but Ubuntu Server also has a long-term supported Kernel 5.15, while Ubuntu Cloud images can choose to use a more optimized Kernel in cooperation with cloud providers. Also, if you're an NVIDIA user, it's worth knowing that a Linux-restricted module for the NVIDIA driver on ARM64 is now available (already available in x86_64). You can use the ubuntu-drivers program to install and configure NVIDIA drivers. Related:
A complete operating system works flawlessly thanks to core modules and subsystems. So, with that in mind, Ubuntu 22.04 LTS upgrades all of these to cater to this great release. Below is a brief introduction. GNU/Linux kernel
- GCC 11.2.0
binutils 2.38
glibc 2.35

performance improvement
But that's not all. Thanks to some long-pending updates, you should experience a faster Ubuntu 22.04 Jammy Jellyfish, finally in this release.
First, the long-pending triple buffering code for the GNOME desktop. Triple buffering is automatically enabled when the previous framebuffer lags, which results in faster desktop performance in both Intel and Raspberry Pi drivers. Not only that, but the code monitors the last frame so the system doesn't overrun the buffer.
Second, improved power management for AMD and NVIDIA GPUs at runtime will help laptop users.
Additionally, Wayland is now the default display server for most systems, except for NVIDIA GPU hardware which defaults to X11. Wayland gives you a faster desktop experience across applications, including web browsers.
Finally, the customized GNOME 42 with its unique features such as Balanced and Power Saving power profiles gives heavy laptop users even more advantages. Also, new accent colors with a light/dark look and GTK4/libadwaita ports of selected GNOME modules are just a few addons to this epic Ubuntu 22.04 LTS release.
in conclusion
All in all, with all the changes above and many others, I believe this is one of the best LTS releases Canonical has ever released.
