Ubuntu 的粉丝们！现在是时候为下一个大版本，也就是 Ubuntu 22.04 LTS 感到激动了。是的。这是一个长期支持版本，它将被支持五年，直到 2027 年 4 月。


即将发布的 LTS 版本带来了一些新的功能。如果你正在使用 Ubuntu 20.04 LTS，你会注意到许多视觉上的变化。如果你正在使用 Ubuntu 21.10，你已经看到了大量的变化，但在这个即将发布的版本中仍然会有一些新的变化。


在我向你展示 22.04 中新的预期新功能之前，让我们看看它将在什么时候发布。


### Ubuntu 22.04 发布时间表


Ubuntu 22.04 的稳定版计划于 2022 年 4 月 21 日发布。开发工作已经在紧锣密鼓地进行，它将遵循如下发布时间表：


* 2022 年 2 月 24 日：功能冻结
* 2022 年 3 月 17 日：用户界面冻结
* 2022 年 3 月 31 日：测试版发布
* 2022 年 4 月 14 日：候选版本
* **2022 年 4 月 21 日：最终稳定版本**


现在你知道了重要的发布日期，是时候了解一下 Ubuntu 22.04 LTS 将带来的新功能了。


### Ubuntu 22.04 LTS “Jammy Jellyfish” 的新功能


由于开发工作仍在进行中，许多新功能会在不久的将来陆续加入。我将在它们被发现时进行更新。


现在，这里是 Ubuntu 22.04 中主要的已确认和预期的新功能。


#### GNOME 42 和随之而来的视觉变化


GNOME 42 将于 2022 年 3 月发布。它将被包含在 Ubuntu 22.04 中。


像往常一样，Ubuntu 将使用定制的 GNOME 版本，所以不是所有的 GNOME 42 的变化都会反映在这里。然而，由于使用了新的 libadwaita 和迁移到了 GTK 4，你还是应该看到一些视觉变化。


![GNOME 42 有一个重新打造的屏幕截图工具](/data/attachment/album/202201/14/111930fg52gauakb0r7s77.png)


你应该看到一个界面崭新的设置程序和重新打造的屏幕截图工具。GNOME 42 还将更新一些 GNOME 应用程序，如 Boxes，并引入一个新的文本编辑器。然而，我认为 Ubuntu 会坚持使用 Gedit 作为其默认的文本编辑器。


#### Grub 2.06 和它带来的麻烦


Ubuntu 22.04 LTS 将拥有 [Grub 引导加载程序](https://itsfoss.com/what-is-grub/) 2.06 版本，但其中有一个问题，它的 os-prober 功能默认是禁用的。


这意味着，如果你在一个双启动系统上，Grub 不会探测其他操作系统，因此它不会在 Grub 中列出 Windows（或其他操作系统）。一些升级到 Ubuntu 22.04 开发版本的人已经 [开始面临这个问题](https://itsfoss.community/t/windows-10-boot-option-missing-in-grub-after-upgrading-to-ubuntu-22-04-developer-version/8306/5)。


这并不是说这个问题不能被解决，有一个变通办法。


安装 os-prober（通常已经安装），然后编辑 `/etc/default/grub` 文件，在这个文件中加入 `GRUB_DISABLE_OS_PROBER=false`。保存这个文件，[更新 Grub](https://itsfoss.com/update-grub/)，Grub 现在应该可以看到其他操作系统了。


#### 新的固件更新程序


正如 [OMG! Ubuntu](https://www.omgubuntu.co.uk/2021/11/ubuntu-is-working-on-a-new-firmware-updater-app) 报道的那样，Ubuntu 22.04 可能会有一个新的固件更新程序。


通常情况下，GNOME 软件中心能够处理固件更新，即使在 Ubuntu 的 Snap 版本中。尽管如此，开发团队仍在努力开发一个专门的 GUI 工具来处理固件更新。


![图片来源：OMG! Ubuntu](/data/attachment/album/202201/14/111931l58y3jfjzg7zfhpa.jpg)


这个新工具基本上是 `fwupd` 的基于 Flutter 和 Dart 的 GUI 前端，`fwupd` 是一个命令行工具，用于获取 [Linux 供应商的固件](https://fwupd.org/)。


#### 新的安装程序


![新的 Ubuntu 安装程序](/data/attachment/album/202201/14/111931f7uwsexdq69w7ciz.jpg)


这个基于 Flutter 的新安装程序已经开发了很长时间。它本来应该和 Ubuntu 21.10 一起推出，但并没如期实现。有一个单独的 Ubuntu 21.10 预览版，其中有这个新的安装程序，它将成为 Ubuntu 22.04 的默认安装程序。


新的安装程序与 Ubuntu 桌面风格无缝整合，从而使 Ubuntu 22.04 从一开始就具有更现代的外观和感觉。


#### 改进对树莓派的支持


随着 20.10 版本的发布，Ubuntu 开始支持树莓派设备上运行桌面版。虽然它可以在 8GB 版本的树莓派上工作，但在 4GB 上却很吃力，在 2GB 型号上也无法工作。


随着 Ubuntu 22.04 的推出，其性能应该会得到改善，特别是它 [引入了 zswap](https://www.omgubuntu.co.uk/2022/01/ubuntu-on-raspberry-pi-4-2gb-zswap)。


#### 其他变化


在软件供应方面，你应该看到一些其他变化。大多数著名的软件应该有较新的版本。其中一些是：


* OpenSSL 3.0
* Ruby 3.0
* Python 3.10
* PHP 8.1
* GCC 11（预计）


目前还没有确认，但更有可能的是 Ubuntu 22.04 将采用 Linux 内核 5.17。


正如我之前所说，一切正在开发中，一旦有更多的新功能被披露，我将立即更新这篇文章。


### 获取 Ubuntu 22.04 LTS


**警告**：Ubuntu 22.04 仍在努力开发中，你不应该在生产机器或你的主系统上使用它。


如果你想在备用机或虚拟机上测试它，你可以从 Ubuntu 的网站上下载日常构建版。


* [下载 Ubuntu 22.04 日常构建版（不稳定）](https://cdimage.ubuntu.com/daily-live/current/)


如果你在备用机上使用 Ubuntu 20.04 LTS 或 Ubuntu 21.10，你可以强制升级到开发分支。


### 你期待 Ubuntu 22.04 的哪些功能？


很明显，GNOME 42 将是 Ubuntu 22.04 的最大亮点。你希望在这个新的 LTS 版本中看到哪些功能？

Ubuntu fans! It’s time to get excited about the next big release which is Ubuntu 22.04 LTS. Yes. It is a long-term support release and it will be supported for five years till April 2027.

The upcoming LTS release brings several new features. If you are using Ubuntu 20.04 LTS, you will notice numerous visual changes. If you are using Ubuntu 21.10, you already have seen plenty of changes but there will still be a few new ones in the upcoming release.

## New features in Ubuntu 22.04 LTS Jammy Jellyfish

![ubuntu 22 04 jammy jellyfish wallpaper](https://itsfoss.com/content/images/wordpress/2022/04/ubuntu-22-04-jammy-jellyfish-wallpaper-800x450.jpg)

There are several visual and under the hood changes in this release. Since it is easy to show the visual features, my focus will be on these visual changes, followed by the under-the-hood changes.

Most of the visual features come with the GNOME 3.42 version. Some are additionally added (or removed) by the Ubuntu development team.

I made a video to show some features in action:

### 1. New dock mode

Ever since Ubuntu switched to GNOME as the default desktop environment, it has featured a Unity-styled full-length launcher. However, the vanilla GNOME has a shorter launcher.

Ubuntu 22.04 has a surprise new addition where you can change the size of the dock (basically detach it from the left-side to a floating look)

![Ubuntu 22.04 new dock mode](https://itsfoss.com/content/images/wordpress/2022/04/ubuntu-22-04-new-dock-mode-800x450.jpg)

It works best when combined with the auto-hide feature. You can see it when you disable the Panel mode, as shown in the image below.

![ubuntu 22 04 dock shrink](https://itsfoss.com/content/images/wordpress/2022/04/ubuntu-22-04-dock-shrink.jpg)

### 2. Accent Color Selection

![ubuntu 22 04 appearance settings](https://itsfoss.com/content/images/wordpress/2022/03/ubuntu-22-04-appearance-settings.png)

With Ubuntu 22.04, you can now [choose a different accent color](https://itsfoss.com/accent-color-ubuntu/).

If you dislike the default orange theme, the accent color choices should help you personalize the desktop experience.

The folder icons, the notification bar, buttons, and various other elements in your system will reflect the selected accent color.

### 3. New screenshot and screencast tool

Thanks to GNOME 42, Ubuntu 22.04 has a revamped screenshot tool that also includes the screencast (video recording of desktop) option.

The new UI lets you take the screenshot of the selected area, entire screen or current application window. The screenshots are copied to clipboard and saved to the Screenshots folder under Pictures directory.

![new screenshot tool ubuntu 22 04](https://itsfoss.com/content/images/wordpress/2022/04/new-screenshot-tool-ubuntu-22-04-800x450.jpg)

The screencast option works under Wayland. That’s a good news. However, there is no configuration option on frame rate, output quality etc. The recorded videos were in poor quality in my test.

### 4. New multitasking setting

No need to use GNOME Tweaks tool to access these settings the new 22.04 LTS version. The new multitasking settings allows you to enable hot corners. With that, when you move the cursor to the top left corner, it brings the activities area. Otherwise, you have to go to the left corner and click the Activities option.

![multitasking settings ubuntu 22 04](https://itsfoss.com/content/images/wordpress/2022/04/multitasking-settings-ubuntu-22-04-800x664.png)

You can also disable the screen edge effect from the multitasking settings. I prefer to have this setting active because it is very helpful when you are multitasking. Keep a PDF or website open in half of the screen and keep the IDE or terminal open in the other half.

There is also option to control the number of workspaces and their behavior. If you have multi monitor setup, you can choose whether the workspaces will be displayed on all monitors or just the primary one.

### 5. Wayland is default again

With version 22.04, Ubuntu switches to the Wayland display server by default once again. However, it will be limited to systems without Nvidia graphics cards at the time of release due to some known issues.

Hopefully, the Wayland experience has improved as we get to use it. In either case, you can [switch back to the legacy X display server](https://itsfoss.com/switch-xorg-wayland/).

### 6. Grub 2.06 and the trouble that comes with it

Ubuntu 22.04 LTS will have [Grub bootloader](https://itsfoss.com/what-is-grub/) version 2.06 but there is a problem with it. It has os-prober feature disabled by default.

This means that if you are on a dual boot system, Grub won’t probe for other operating systems and thus it won’t list Windows (or other OS) in Grub. A few people, who upgraded to the development version of Ubuntu 22.04, have already [started facing this issue](https://itsfoss.community/t/windows-10-boot-option-missing-in-grub-after-upgrading-to-ubuntu-22-04-developer-version/8306/5?ref=itsfoss.com).

It’s not that the problem cannot be fixed. There is a workaround.

Install os-prober (usually installed already) and then edit the /etc/default/grub file to add GRUB_DISABLE_OS_PROBER=false to this file. Save this file, [update grub](https://itsfoss.com/update-grub/) and Grub should see other operating systems now.

### 7. New option to enable and disable animations

Ubuntu 22.04 now provides the option to toggle animations in the accessibility settings.

![enable disable animation ubuntu 22 04](https://itsfoss.com/content/images/wordpress/2022/04/enable-disable-animation-ubuntu-22-04-800x552.png)

What does it change? By default, the animation is enabled and though you might not have noticed, when you minimize or maximize application windows, go to the activity overview area, there is a slight effect to make the UI more fluid.

Never noticed it? You can disable it to see the impact. Disabling animation could give you a tiny performance improvement. But it’s mainly for the people who have difficulties with such animation effects. Hence, it is under the accessibility settings.

### 8. Position of desktop icons

![desktop icon ubuntu 22 04](https://itsfoss.com/content/images/wordpress/2022/04/desktop-icon-ubuntu-22-04.jpg)

Another change is about the position of the new desktop icons. By default, it is now in the bottom right corner. If you create new folders or documents, it gets created at the position you had selected.

![ubuntu 22 04 desktop icons position](https://itsfoss.com/content/images/wordpress/2022/04/Ubuntu-22-04-desktop-icons-position-800x450.jpg)

But when you arrange the icons, they get placed in the bottom right. Or you can change their position to top right, bottom left, or top left.

### 9. Controlling mounted drives and trash in Dock

The settings now enables you to control the behavior of mounted drives and trash icon in the dock. You can choose to show the mounted disks in the launcher or hide them as per your preference.

![control usb mount behavior ubuntu](https://itsfoss.com/content/images/wordpress/2022/04/control-usb-mount-behavior-ubuntu-800x450.jpg)

The same goes for the Trash icon.

### 10. Slightly revamped Software Center

Software Center is slightly revamped. The icons are bigger, licensing information is gone and Snaps still get the priority over the DEB version.

![ubuntu software center 22 04](https://itsfoss.com/content/images/wordpress/2022/04/ubuntu-software-center-22-04-800x539.png)

### 11. New icon for Software & Updates

This is really a tiny change but I am happy to see.

Earlier, you had too similar named applications with similar icons: Software Updater and Software & Updates.

![2 overview software and updater](https://itsfoss.com/content/images/wordpress/2022/03/2_Overview_software_and_updater.png)

The icon for Software & Updates is now changed so that it is easier to distinguish between the two applications.

![new software update icon](https://itsfoss.com/content/images/wordpress/2022/04/new-software-update-icon.png)

### 12. Multimonitor settings

If you have two screens, you get the option to join displays, mirror them or use only one of them.

![Multimonitor setting in Ubuntu 22.04](https://itsfoss.com/content/images/wordpress/2022/04/multimonitor-setting-Ubuntu-22-04-800x702.png)

These settings are available for two monitor setup only. For three or more monitors, you won’t see the mirror option. However, you can still drag and arrange their alignment.

### 13. Fractional scaling up to 225%

![fractional scaling in ubuntu 22 04](https://itsfoss.com/content/images/wordpress/2022/04/fractional-scaling-in-ubuntu-22-04-800x674.png)

[Fractional scaling has been available in Ubuntu](https://itsfoss.com/enable-fractional-scaling-ubuntu/) for the past several versions. But it was restricted to 200%. I noticed that in Ubuntu 22.04, the fractional scaling goes up to 225%.

### 14. Brand new logo

![ubuntu 22 04 new logo](https://itsfoss.com/content/images/wordpress/2022/04/ubuntu-22-04-new-logo-800x520.png)

Ubuntu has a new logo and it is visible everywhere in Ubuntu 22.04. You’ll see it while booting into the system, on the login screen, lock screen, and even on the about page.

### 15. New wallpapers but no dark and light variants

GNOME 42 introduced the set of [dual tone wallpapers that get changed based on the dark and light system themes](https://itsfoss.com/dark-light-wallpaper-gnome/). This feature is absent from Ubuntu 22.04.

You do have a bunch of new wallpapers, though.

![ubuntu 22 04 wallpapers](https://itsfoss.com/content/images/wordpress/2022/04/ubuntu-22-04-wallpapers-800x694.png)

### 16. Improved support for Raspberry Pi

Ubuntu started supporting the desktop edition on Raspberry Pi devices with the release of version 20.10. While it could work on the 8 GB version of Raspberry Pi, it struggles on 4 GB and won’t work on 2 GB models.

The performance should improve with Ubuntu 22.04 especially with the [introduction of zswap](https://news.itsfoss.com/ubuntu-desktop-raspberry-pi-4/?ref=itsfoss.com).

### 17. Firefox as Snap

Firefox will now be included as a Snap package by default. While you can install the deb package by downloading it separately, Ubuntu recommends Snap.

This is a joint effort by Canonical and Mozilla to simplify the maintenance of Firefox across distributions, enhance security, and facilitate faster security updates.

### 18. Other changes

There are a few other changes you should see in terms of a software offering. There should be newer versions of most of the prominent software. Some of them are:

- OpenSSL 3.0
- Ruby 3.0
- Python 3.10
- PHP 8.1
- GCC 11

Ubuntu 22.04 features Linux Kernel 5.15 LTS.

As I said earlier, things are in development, and I’ll update this article as soon as more new features are revealed.

### Getting Ubuntu 22.04 LTS

Though Ubuntu 22.04 release has been announced, the ISO will take some time to arrive. Updates for existing users will be roll out in coming days. If you want, you could [force update to Ubuntu 22.04 rig](https://itsfoss.com/upgrade-ubuntu-version/)ht now from 21.10 and 20.04.
