5 Less Popular Features that Make Ubuntu 22.04 LTS an Epic Release
======
A LIST OF MINOR HIGHLIGHTED FEATURES OF UBUNTU 22.04 LTS THAT MAKES IT
ONE OF THE BEST LTS RELEASE SO FAR.
Canonical’s latest LTS instalment of [Ubuntu code-named “Jammy Jellyfish”][1] is well received from users worldwide. There are hundreds of new tiny features and some less popular ones that didn’t catch much attention. So, here are five unique Ubuntu 22.04 release features which we think make it an epic release.
![Ubuntu 22.04 LTS Desktop \(GNOME\)][2]
### Ubuntu 22.04 Release – Five Unique Features
#### Optimised for Data-Driven Solutions
Data analysis and processing are the core of every business today. And to do that, you need enormous computing power. Ubuntu 22.04 LTS brings out of the box [NVIDIA virtual GPU (vGPU)][3] driver support. That means you can take advantage of NVIDIA virtual GPU software, enabling you to use GPU computing power in virtual machines shared from physical GPU servers.
Not only that, if your business relies on SQL Servers, Ubuntu LTS for Azure brings SQL Server for Ubuntu which is backed by “Micro$oft” providing optimised performance and scalability.
#### Improved Active Directory Integration
Furthermore, Many businesses deploy Ubuntu in multiple workstations for the entire enterprise users. And it is important to deploy workstation policies to monitor and control user access and various business-critical controls.
Active Directory, which enables the policy-based workstation administration (introduced in Ubuntu 20.04), is further improved in this release. In addition to that, this release brings [ADsys][4] client, which helps to remotely manage the group policy, privilege escalation and remote script execution via command line. Active Directory also now supports installer integration beginning this release with the Advanced Group Policy object.
#### Realtime Kernel Support
Moreover, one of the interesting announcements from Canonical during the Ubuntu 22.04 LTS release is the offering “real-time” Kernel option, which is now beta. For telecom and other industries, a low-latency operating system is required for time-sensitive work. So, with that in mind and a vision to penetrate those areas, Ubuntu 22.04 LTS brings a real-time kernel build with PREEMPT_RT patches applied. It is avialble for x86_64 and AArch64 architectures.
However, the [patch][5] is not in mainline Kernel yet and hopefully, and it will be streamlined soon.
#### Latest Apps, Packages and Drivers
In addition to the above changes, this release also brings a vast list of package and toolchain upgrades. For example, this release brings multiple Linux Kernel types based on usage, such as Ubuntu desktop can opt into [Kernel 5.17][6], whereas the hardware enablement Kernel remains 5.15.

Not only that, Ubuntu Server features long-term-support [Kernel 5.15][8], while the Ubuntu Cloud images have the option to use a more optimised Kernel in collaboration with cloud providers.
Moreover, if you are an NVIDIA user, it is worth knowing that Linux-restricted modules of NVIDIA drivers on ARM64 are now available (already available in x86_64). You can use the [ubuntu-drivers][9] program to install and configure NVIDIA drivers.
A complete operating system works flawlessly because of core modules and subsystems. So, with that in mind, Ubuntu 22.04 LTS upgraded all of them carefully to cater for this great release. Here’s a brief.
* GCC 11.2.0
* binutils 2.38
* glibc 2.35
* Python 3.10.4
* Perl 5.34.0
* LLVM 14
* golang 1.18
* rustc 1.58
* OpenJDK 11 (option to use OpenJDK 18)
* Ruby 3.0
* PHP 8.1.2Apache 2.4.52
* PostgreSQL 14.2
* Django 3.2.12
* MySQL 8.0
* Updated NFS and Samba Server
* Systemd 249.11
* OpenSSL 3.0
* qemu 6.2.0
* libvirt 8.0.0
* virt-manager 4.0.0
#### Performance Boost
But that’s not all. Thanks to some long-pending updates, you should experience a much faster Ubuntu 22.04 Jammy Jellyfish experience, which eventually lands in this release.
Firstly, the long-pending [Tripple buffering code][10] for GNOME desktop lands. The Tripple buffering is enabled automatically when the prior frame buffering lags behind, and it yields a much faster desktop performance in Intel and Raspberry Pi drivers. Not only that, but the code also monitors the last frame so that the system doesn’t run into excess buffering situations.
Secondly, improved power management that works at runtime for AMD and NVIDIA GPUs will help laptop users.
In addition, Wayland is now the default display server for most systems except for NVIDIA GPU hardware which defaults to X11. Wayland gives you a much faster desktop experience across applications, including web browsers.
Finally, the customised GNOME 42 and its [unique features][11] such as balanced and power saver power profiles gives more advantage to heavy laptop users. Also, the new accent colour with a light/dark look and GTK4/libadwaita port of selected GNOME modules is just an addon to this epic Ubuntu 22.04 LTS release.
### Conclusion
To conclude, I believe this is one of the best LTS releases that Canonical shipped in terms of all the above under the hood changes and many others.
We hope it is well received and remains stable in the coming days.

使 Ubuntu 22.04 LTS 成为史诗版本的 5 个不太流行的功能
======
一份关于 Ubuntu 22.04 LTS 的次要特点的列表，这些特点使它成为迄今为止最好的 LTS 版本之一。
Canonical 的最新 LTS 版本 [Ubuntu 代号为 “Jammy Jellyfish”][1] 受到了全球用户的好评。有数百个新的微小功能，也有一些不太流行的功能，没有引起人们的注意。因此，这里有五个独特的 Ubuntu 22.04 版本功能，我们认为这些功能使它成为一个史诗般的版本。
![Ubuntu 22.04 LTS Desktop \(GNOME\)][2]
### Ubuntu 22.04 发布 – 五个独特的功能
#### 为数据驱动的方案进行了优化
数据分析和处理是当今每个企业的核心。而要做到这一点，你需要巨大的计算能力。Ubuntu 22.04 LTS 带来了开箱即用的 [NVIDIA 虚拟 GPU（vGPU）][3] 驱动支持。这意味着你可以利用 NVIDIA 虚拟 GPU 软件，使你能够在从物理 GPU 服务器共享的虚拟机中使用 GPU 计算能力。
不仅如此，如果你的业务依赖于 SQL Server，Ubuntu LTS for Azure 带来了 Ubuntu 中的 SQL Server，它由 “Micro$oft” 支持，提供优化的性能和可扩展性。
#### 改进的活动目录集成
此外，许多企业在多个工作站中为整个企业用户部署 Ubuntu。而且，部署工作站策略以监测和控制用户访问和各种关键业务控制非常重要。
活动目录实现了基于策略的工作站管理（在 Ubuntu 20.04 中引入），在这个版本中得到了进一步改善。除此之外，这个版本还带来了 [ADsys][4] 客户端，它有助于通过命令行远程管理组策略、权限升级和远程脚本执行。活动目录现在也支持从这个版本开始与高级组策略对象的安装程序集成。
#### 实时内核支持
此外，在 Ubuntu 22.04 LTS 发布期间，Canonical 宣布的一个有趣的消息是提供“实时”内核选项，现在是测试版。对于电信和其他行业来说，一个低延迟的操作系统对于时间敏感的工作是必需的。因此，考虑到这一点和渗透到这些领域的愿景，Ubuntu 22.04 LTS 带来了一个应用了 PREEMPT_RT 补丁的实时内核构建。它可用于 x86_64 和 AArch64 架构。
然而，[补丁][5]还没有在主线内核中出现，希望它能很快能出现。
#### 最新的应用、软件包和驱动程序
除了上述变化之外，这个版本还带来了大量的软件包和工具链的升级。例如，这个版本带来了基于用途的多种 Linux 内核类型，如 Ubuntu 桌面可以选择使用 [Kernel 5.17][6]，而硬件启用的内核仍然是 5.15。
不仅如此，Ubuntu Server 的特点是长期支持 [Kernel 5.15][8]，而 Ubuntu Cloud 镜像可以选择使用与云供应商合作的更优化的内核。
此外，如果你是 NVIDIA 用户，值得一提的是，ARM64 上的 NVIDIA 驱动的 Linux 限制模块现在已经可用（在 x86_64 中已经可用）。你可以使用 [ubuntu-drivers][9] 程序来安装和配置 NVIDIA 驱动。
由于核心模块和子系统的存在，一个完整的操作系统可以完美无缺地工作。因此，考虑到这一点，Ubuntu 22.04 LTS 对它们都进行了仔细的升级，以迎合这个很好的版本。以下是简介。
* GCC 11.2.0
* binutils 2.38
* glibc 2.35
* Python 3.10.4
* Perl 5.34.0
* LLVM 14
* golang 1.18
* rustc 1.58
* OpenJDK 11（可选使用 OpenJDK 18）
* Ruby 3.0
* PHP 8.1.2Apache 2.4.52
* PostgreSQL 14.2
* Django 3.2.12
* MySQL 8.0
* 更新的 NFS 以及 Samba Server
* Systemd 249.11
* OpenSSL 3.0
* qemu 6.2.0
* libvirt 8.0.0
* virt-manager 4.0.0
#### 性能提升
但这还不是全部。由于一些长期等待的更新，你应该体验到更快的 Ubuntu 22.04 Jammy Jellyfish 体验，这些体验最终会在这个版本中出现。
首先，GNOME 桌面的[三重缓冲代码]长期悬而未决。当先前的帧缓冲落后时，三重缓冲会自动启用，它在 Intel 和树莓派驱动中产生了更快的桌面性能。不仅如此，代码还监控最后一帧，以便系统不会遇到过量缓冲的情况。
其次，改进的电源管理，在运行时对 AMD 和 NVIDIA 的 GPU 起作用，将帮助笔记本电脑用户。
此外，Wayland 现在是大多数系统的默认显示服务器，除了 NVIDIA GPU 硬件默认为 X11。Wayland 为你提供了更快的跨应用的桌面体验，包括网络浏览器。
最后，定制的 GNOME 42 及其[独特功能][11]（例如平衡和省电电源配置文件）为重度笔记本电脑用户提供了更多优势。 此外，带有浅色/深色外观的新强调色和选定 GNOME 模块的 GTK4/libadwaita 端口只是这个史诗般的 Ubuntu 22.04 LTS 版本的一个插件。
### 结论
总而言之，我相信这是 Canonical 发布的最好的 LTS 版本之一，就上述所有内容的变化和许多其他方面而言。
我们希望它受到好评并在未来几天保持稳定。
