### Lubuntu 20.04 点评：第一个基于 LXQt 的长期支持版


我在 Lubuntu 20.04 发行前几天就已经开始使用它了。我通常使用 Arch 阵营中 Manjaro 和 Cinnamon 桌面，所以使用 Lubuntu 对我来说是一个愉快的改变。


以下是我在使用 Lubuntu 20.04.时的一些感受和注记。


#### 再见 LXDE，你好 LXQt！


长期以来，[Lubuntu](https://lubuntu.me/) 都依靠 [LXDE](https://github.com/lxde) 来提供轻量级的 Linux 体验。但现在，它使用的是 LXQt 桌面环境。


[LXDE](https://lxde.org/) 是基于 GTK（GNOME 所使用的库），更具体地说是基于 2020 年的 GTK+ 2。由于对 GTK+ 3 不满意，LXDE 开发人员 Hong Jen Yee 决定将整个桌面移植到 Qt（KDE 所使用的库）。LXDE 的 Qt 移植版本和 [Razor-qt](https://web.archive.org/web/20160220061334/http://razor-qt.org/) 项目合并形成 [LXQt](https://lxqt.org/)。所以现在，LXDE 和 LXQt 作为单独的项目而共存。


既然 LXDE 开发者本身专注于 LXQt，那么 Lubuntu 坚持使用三年多前上一次稳定发布版的桌面环境 LXDE 是没有意义的。


因此，Lubuntu 18.04 是使用 [LXDE](https://lxde.org/) 的最后一个版本。幸运的是，这是一个长期支持版本。Lubuntu 团队将提供支持直到 2021 年。

#### 不仅适于老机器


随着在 2020 年“老机器”的定义发生了变化，Lubuntu 18.04 成为了最后一个 32 位版本。现在，即使是一台 10 年前的老机器也至少有 2G 的内存和一个双核 64 位处理器。


因此，Lubuntu 团队将不再设置最低的系统需求，也不再主要关注旧硬件。尽管 LXQt 仍然是一个轻量级的、经典而不失精致的、功能丰富的桌面环境。


在 Lubuntu 20.04 LTS 发布之前，Lubuntu 的第一个 LXQt 发行版是 18.10，开发人员经历了三个标准发行版来完善 LXQt 桌面，这是一个很好的开发策略。


#### 不用常规的 Ubiquity，Lubuntu 20.04 使用的是 Calamares 安装程序


![](/data/attachment/album/202005/23/133509wg8nmgfx9pnaugcg.jpg)


在新版本中使用了全新的 [Calamares](https://calamares.io/) 安装程序，取代了其它 [Ubuntu 官方版本](https://itsfoss.com/which-ubuntu-install/)使用的 Ubiquity 安装程序。


整个安装过程在大约能在 10 分钟内完成，比之前 Lubuntu 的版本稍微快一些。


由于镜像文件附带了预先安装的基本应用程序，所以你可以很快就可以完成系统的完全配置。


#### 不要直接从 Lubuntu 18.04 升级到 Lubuntu 20.04


通常，你可以[将 Ubuntu 从一个 LTS 版本升级到另一个 LTS 版本](https://itsfoss.com/upgrade-ubuntu-version/)。但是 Lubuntu 团队建议不要从 Lubuntu 18.04 升级到 20.04。他们建议重新安装，这才是正确的。


Lubuntu 18.04 使用 LXDE 桌面，20.04 使用 LXQt。由于桌面环境的巨大变化，从 18.04 升级到 20.04 将导致系统崩溃。


#### 更多的 KDE 和 Qt 应用程序


![](/data/attachment/album/202005/23/133546ytjfqniuacatucir.gif)


下面是在这个新版本中默认提供的一些应用程序，正如我们所看到的，并非所有应用程序都是轻量级的，而且大多数应用程序都是基于 Qt 的。


甚至使用的软件中心也是 KDE 的 Discover，而不是 Ubuntu 的 GNOME 软件中心。


* Ark – 归档文件管理器
* Bluedevil – 蓝牙连接管理
* Discover 软件中心 – 包管理系统
* FeatherPad – 文本编辑器
* FireFox – 浏览器
* K3b – CD/DVD 刻录器
* Kcalc – 计算器
* KDE 分区管理器 – 分区管理工具
* LibreOffice – 办公套件（Qt 界面版本）
* LXimage-Qt – 图片查看器及截图制作
* Muon – 包管理器
* Noblenote – 笔记工具
* PCManFM-Qt – 文件管理器
* Qlipper – 剪贴板管理工具
* qPDFview – PDF 阅读器
* PulseAudio – 音频控制器
* Qtransmission – BT 下载工具（Qt 界面版本）
* Quassel – IRC 客户端
* ScreenGrab – 截屏制作工具
* Skanlite – 扫描工具
* 启动盘创建工具 – USB 启动盘制作工具
* Trojita – 邮件客户端
* VLC – 媒体播放器
* [MPV 视频播放器](https://itsfoss.com/mpv-video-player/)


#### 测试 Lubuntu 20.04 LTS


LXQt 版 Lubuntu 的启动时间不到一分钟，虽然是从 SSD 启动的。


LXQt 目前需要的内存比基于 Gtk+ 2 的 LXDE 稍微多一点，但是另一种 Gtk+ 3 工具包也需要更多的内存。


在重新启动之后，系统以非常低的内存占用情况运行，大约只有 340 MB（按照现代标准），比 LXDE 多 100 MB。


![](/data/attachment/album/202005/23/133558asy8t83t74763a7a.jpg)


LXQt 不仅适用于硬件较旧的用户，也适用于那些希望在新机器上获得简约经典体验的用户。


桌面布局看起来类似于 KDE 的 Plasma 桌面，你觉得呢?


![](/data/attachment/album/202005/23/133612eszrsd3oocoendpu.jpg)


在左下角有一个应用程序菜单，一个用于显示固定和活动的应用程序的任务栏，右下角有一个系统托盘。


Lubuntu 的 LXQt 版本可以很容易的定制，所有的东西都在菜单的首选项下，大部分的关键项目都在 LXQt “设置”中。


值得一提的是，LXQt 在默认情况下使用流行的 [Openbox 窗口管理器](https://en.wikipedia.org/wiki/Openbox)。


与前三个发行版一样，20.04 LTS 附带了一个默认的黑暗主题 Lubuntu Arc，但是如果不适合你的口味，可以快速更换，也很方便。


就日常使用而言，事实证明，Lubuntu 20.04 向我证明，其实每一个 Ubuntu 的分支版本都完全没有问题。


#### 结论


Lubuntu 团队已经成功地过渡到一个现代的、依然轻量级的、极简的桌面环境。LXDE 看起来被遗弃了，迁移到一个活跃的项目也是一件好事。


我希望 Lubuntu 20.04 能够让你和我一样热爱，如果是这样，请在下面的评论中告诉我。请继续关注!

*Lubuntu 20.04 LTS is significantly different than its previous LTS version. It is aiming to give you a more polished experience rather than just focusing on older computer. Read more about it as I review Lubuntu 20.04.*

## Lubuntu 20.04 Review: First LTS release with LXQt

I have been using Lubuntu 20.04 from a few days before the release. I usually dwell in Arch world with Manjaro and Cinnamon desktop so using Lubuntu was a pleasant change for me.

Here’s what I have noticed and felt about Lubuntu 20.04.

### Bye bye LXDE, Hello LXQt!

For a long time, [Lubuntu](https://lubuntu.me/) relied on [LXDE](https://github.com/lxde) to provide a lightweight Linux experience. It now uses LXQt desktop environment.

[LXDE](http://lxde.org/) is based on GTK (the libraries used by GNOME) and more specifically on GTK+ 2 which is dated in 2020. Dissatisfied with GTK+ 3, LXDE developer Hong Jen Yee decided to port the entire desktop to Qt (the libraries used by KDE). LXDE, the Qt port of it, and the [Razor-qt](https://web.archive.org/web/20160220061334/http://razor-qt.org/) project were combined to form [LXQt](http://lxqt.org/). Although today, LXDE and LXQt coexist as separate projects.

Since LXDE developer itself is focusing on LXQt, it makes no sense for Lubuntu to stick with a desktop environment that had its last stable release more than three years ago.

Lubuntu 18.04 is the last version of with [LXDE](https://lxde.org/). Fortunately it’s a long term support edition. It will be supported officially by Lubuntu team till 2021.

![Lubuntu 20.04 Review](https://itsfoss.com/content/images/wordpress/2020/04/Lubuntu-20-04-review.jpg)

### Not exclusively for older machines

As the definition of “older machine” has changed in 2020 Lubuntu 18.04 is the last 32bit version. Nowadays even a 10 year old machine comes with at least 2 gigabytes of ram and a dual-core 64bit processor.

As per that, [Lubuntu Team will no longer provide minimum system requirements and will no longer primarily focus on older hardware](https://itsfoss.com/lubuntu-no-more-old-distro/). Although LXQt is still a lightweight, classic yet polished and feature rich desktop environment.

The First Lubuntu release with LXQt was 18.10, giving the developers three standard releases to perfect the LXQt desktop before the Lubuntu 20.04 LTS release, which is a good development strategy.

### Not the regular Ubiquity, Lubuntu 20.04 uses Calamares installer

![Lubuntu 20 04 Installer](https://itsfoss.com/content/images/wordpress/2020/04/lubuntu-20-04-installer.jpg)

A fresh installation begins with the new [Calamares](https://calamares.io/) installer, in place of the Ubiquity installer that other [official Ubuntu flavors](https://itsfoss.com/which-ubuntu-install/) use.

The whole process is done in approximately 10 minutes, slightly faster than the previous Lubuntu releases.

As the .iso comes with the essential applications pre-installed you can get your system fully configured pretty fast too.

### No upgrade from Lubuntu 18.04 to Lubuntu 20.04

Normally, you can [upgrade Ubuntu from one LTS to another LTS release](https://itsfoss.com/upgrade-ubuntu-version/). But Lubuntu team advises not to upgrade from Lubuntu 18.04 to 20.04. They recommend a fresh install and rightly so.

Lubuntu 18.04 used LXDE desktop while 20.04 uses LXQt. Due to the extensive changes in the desktop environments, upgrading to 20.04 from 18.04 will result in a broken system.

**More KDE and Qt applications**

![Lubuntu 20.04](https://itsfoss.com/content/images/wordpress/2020/04/Lubuntu-20.04.gif)

Here are some of the applications that are available by default in this new release and as I can see, not all of them are lightweight and most of them are Qt-based.

Even the software center used is KDE’s Discover instead of Ubuntu’s GNOME software center.

- Ark – archive manager
- Bluedevil – bluetooth connector
- Discover Software Center – package management system
- FeatherPad – text editor
- FireFox – web browser
- K3b – CD/DVD burner
- Kcalc – calculator
- KDE partition manager – partition manager
- LibreOffice – Office suite (Qt interface version)
- LXimage-Qt – image viewer and screenshot tool
- Muon – package manager

- Noblenote – note taker
- PCManFM-Qt – File manager
- Qlipper – clipboard manager
- qPDFview – PDF viewer
- PulseAudio – audio controller
- Qtransmission – bittorrent client (Qt interface version)
- Quassel – IRC client
- ScreenGrab – Screenshot creator
- Skanlite – scanning
- Startup Disk Creator – USB boot disk maker
- Trojita – email client
- VLC – media player

### Testing Lubuntu 20.04 LTS

Boot times on the LXQt version of Lubuntu are under a minute, booting from an SSD though.

LXQt currently requires slightly more memory than the Gtk+ v2-based LXDE, but the alternative Gtk+ v3 toolkit would also have required more memory.

After a reboot the system runs approximately at a very low of 340 MB for the modern standards, 100 MB more than LXDE.

![Htop](https://itsfoss.com/content/images/wordpress/2020/04/htop.jpg?fit=800%2C629&ssl=1)

LXQt is not only for users with an older hardware but also for those who are seeking a simple and classic experience at their new machine.

The desktop layout looks similar to KDE’s Plasma desktop, don’t you think?

![Lubuntu 20.04 Desktop](https://itsfoss.com/content/images/wordpress/2020/04/Lubuntu-20.04-desktop.jpg?fit=800%2C450&ssl=1)

There’s an application menu in the lower-left corner, a taskbar for pinned and active applications, and a system tray in the lower-right corner.

Lubuntu in its LXQt version can be easily customized and everything is in the menu under preferences, with most key items under LXQt Settings.

It is worth-mentioning that LXQt uses the popular [Openbox window manager](https://en.wikipedia.org/wiki/Openbox) by default.

Like the last three releases, 20.04 LTS comes with a default dark theme Lubuntu Arc, but it is quick and easy to change it if it doesn’t suit your taste.

In daily use, Lubuntu 20.04 has proven to me completely trouble-free as every Ubuntu flavour in fact.

### Conclusion

Lubuntu team has successfully made the transition to a modern, still lightweight and minimal desktop environment. LXDE looks like abandoned and it is a good thing to move away to an active project.

I hope that Lubuntu 20.04 makes you as much enthusiastic as I am, and if so don’t hesitate to let me know at the comments below. Stay tuned!
