How To Remove Or Disable Ubuntu Dock
|
||||
======
|
||||
|
||||
|
||||
|
||||
**If you want to replace the Ubuntu Dock in Ubuntu 18.04 with some other dock (like Plank dock for example) or panel, and you want to remove or disable the Ubuntu Dock, here's what you can do and how.**
|
||||
|
||||
Ubuntu Dock - the bar on the left-hand side of the screen which can be used to pin applications and access installed applications -
|
||||
|
||||
|
||||
### How to access the Activities Overview without Ubuntu Dock
|
||||
|
||||
Without Ubuntu Dock, you may have no way of accessing the Activities / installed application list (which can be accessed from Ubuntu Dock by clicking on Show Applications button at the bottom of the dock). For example if you want to use Plank dock.
|
||||
|
||||
Obviously, that's not the case if you install Dash to Panel extension to use it instead Ubuntu Dock, because Dash to Panel provides a button to access the Activities Overview / installed applications.
|
||||
|
||||
Depending on what you plan to use instead of Ubuntu Dock, if there's no way of accessing the Activities Overview, you can enable the Activities Overview Hot Corner option and simply move your mouse to the upper left corner of the screen to open the Activities. Another way of accessing the installed application list is using a keyboard shortcut: `Super + A` .
|
||||
|
||||
If you want to enable the Activities Overview hot corner, use this command:
|
||||
```
|
||||
gsettings set org.gnome.shell enable-hot-corners true
|
||||
|
||||
```
|
||||
|
||||
If later you want to undo this and disable the hot corners, you need to use this command:
|
||||
```
|
||||
gsettings set org.gnome.shell enable-hot-corners false
|
||||
|
||||
```
|
||||
|
||||
You can also enable or disable the Activities Overview Hot Corner option by using the Gnome Tweaks application (the option is in the `Top Bar` section of Gnome Tweaks), which can be installed by using this command:
|
||||
```
|
||||
sudo apt install gnome-tweaks
|
||||
|
||||
```
|
||||
|
||||
### How to remove or disable Ubuntu Dock
|
||||
|
||||
Below you'll find 4 ways of getting rid of Ubuntu Dock which work in Ubuntu 18.04.
|
||||
|
||||
**Option 1: Remove the Gnome Shell Ubuntu Dock package.**
|
||||
|
||||
The easiest way of getting rid of the Ubuntu Dock is to remove the package.
|
||||
|
||||
This completely removes the Ubuntu Dock extension from your system, but it also removes the `ubuntu-desktop` meta package. There's no immediate issue if you remove the `ubuntu-desktop` meta package because does nothing by itself. The `ubuntu-meta` package depends on a large number of packages which make up the Ubuntu Desktop. Its dependencies won't be removed and nothing will break. The issue is that if you want to upgrade to a newer Ubuntu version, any new `ubuntu-desktop` dependencies won't be installed.
|
||||
|
||||
As a way around this, you can simply install the `ubuntu-desktop` meta package before upgrading to a newer Ubuntu version (for example if you want to upgrade from Ubuntu 18.04 to 18.10).
|
||||
|
||||
If you're ok with this and want to remove the Ubuntu Dock extension package from your system, use the following command:
|
||||
```
|
||||
sudo apt remove gnome-shell-extension-ubuntu-dock
|
||||
|
||||
```
|
||||
|
||||
If later you want to undo the changes, simply install the extension back using this command:
|
||||
```
|
||||
sudo apt install gnome-shell-extension-ubuntu-dock
|
||||
|
||||
```
|
||||
|
||||
Or to install the `ubuntu-desktop` meta package back (this will install any ubuntu-desktop dependencies you may have removed, including Ubuntu Dock), you can use this command:
|
||||
```
|
||||
sudo apt install ubuntu-desktop
|
||||
|
||||
```
|
||||
|
||||
**Option 2: Install and use the vanilla Gnome session instead of the default Ubuntu session.**
|
||||
|
||||
Another way to get rid of Ubuntu Dock is to install and use the vanilla Gnome session. Installing the vanilla Gnome session will also install other packages this session depends on, like Gnome Documents, Maps, Music, Contacts, Photos, Tracker and more.
|
||||
|
||||
By installing the vanilla Gnome session, you'll also get the default Gnome GDM login / lock screen theme instead of the Ubuntu defaults as well as Adwaita Gtk theme and icons. You can easily change the Gtk and icon theme though, by using the Gnome Tweaks application.
|
||||
|
||||
Furthermore, the AppIndicators extension will be disabled by default (so applications that make use of the AppIndicators tray won't show up on the top panel), but you can enable this by using Gnome Tweaks (under Extensions, enable the Ubuntu appindicators extension).
|
||||
|
||||
In the same way, you can also enable or disable Ubuntu Dock from the vanilla Gnome session, which is not possible if you use the Ubuntu session (disabling Ubuntu Dock from Gnome Tweaks when using the Ubuntu session does nothing).
|
||||
|
||||
If you don't want to install these extra packages required by the vanilla Gnome session, this option of removing Ubuntu Dock is not for you so check out the other options.
|
||||
|
||||
If you are ok with this though, here's what you need to do. To install the vanilla Gnome session in Ubuntu, use this command:
|
||||
```
|
||||
sudo apt install vanilla-gnome-desktop
|
||||
|
||||
```
|
||||
|
||||
After the installation finishes, reboot your system and on the login screen, after you click on your username, click the gear icon next to the `Sign in` button, and select `GNOME` instead of `Ubuntu` , then proceed to login:
|
||||
|
||||
|
||||
|
||||
In case you want to undo this and remove the vanilla Gnome session, you can purge the vanilla Gnome package and then remove the dependencies it installed (second command) using the following commands:
|
||||
```
|
||||
sudo apt purge vanilla-gnome-desktop
|
||||
sudo apt autoremove
|
||||
|
||||
```
|
||||
|
||||
Then reboot and select Ubuntu in the same way, from the GDM login screen.
|
||||
|
||||
**Option 3: Permanently hide the Ubuntu Dock from your desktop instead of removing it.**
|
||||
|
||||
If you prefer to permanently hide the Ubuntu Dock from showing up on your desktop instead of uninstalling it or using the vanilla Gnome session, you can easily do this using Dconf Editor. The drawback to this is that Ubuntu Dock will still use some system resources even though you're not using in on your desktop, but you'll also be able to easily revert this without installing or removing any packages.
|
||||
|
||||
Ubuntu Dock is only hidden from your desktop though. When you go in overlay mode (Activities), you'll still see and be able to use Ubuntu Dock from there.
|
||||
|
||||
To permanently hide Ubuntu Dock, use Dconf Editor to navigate to `/org/gnome/shell/extensions/dash-to-dock` and disable (set them to false) the following options: `autohide` , `dock-fixed` and `intellihide` .
|
||||
|
||||
You can achieve this from the command line if you wish, buy running the commands below:
|
||||
```
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock autohide false
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock dock-fixed false
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock intellihide false
|
||||
|
||||
```
|
||||
In case you change your mind and you want to undo this, you can either use Dconf Editor and re-enable (set them to true) autohide, dock-fixed and intellihide from `/org/gnome/shell/extensions/dash-to-dock` , or you can use these commands:
|
||||
```
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock autohide true
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock dock-fixed true
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock intellihide true
|
||||
|
||||
```
|
||||
|
||||
**Option 4: Use Dash to Panel extension.**
|
||||
|
||||
You can install Dash to Panel from
|
||||
|
||||
If you change your mind and you want Ubuntu Dock back, you can either disable Dash to Panel by using Gnome Tweaks app, or completely remove Dash to Panel by clicking the X button next to it from here:

如何移除或禁用 Ubuntu Dock
|
||||
======
|
||||
|
||||
|
||||
|
||||
**如果你想用其它 dock（例如 Plank dock）或面板来替换 Ubuntu 18.04 中的 Dock，或者你想要移除或禁用 Ubuntu Dock，本文会告诉你如何做。**
|
||||
|
||||
Ubuntu Dock - 屏幕左侧栏，可用于固定应用程序或访问已安装的应用程序。使用默认的 Ubuntu 会话时，[无法][1]使用 Gnome Tweaks 禁用它。如果你需要，还是有几种方法来摆脱它的。下面我将列出 4 种方法可以移除或禁用 Ubuntu Dock，以及每个方法的缺点（如果有的话），还有如何撤销每个方法的更改。本文还包括在没有 Ubuntu Dock 的情况下访问多任务视图和已安装应用程序列表的其它方法。
|
||||
（to 校正：Activities Overview 在本文翻译为多任务视图，如有不妥，请改正）
|
||||
### 如何在没有 Ubuntu Dock 的情况下访问多任务试图
|
||||
|
||||
如果没有 Ubuntu Dock，你可能无法访问活动的或已安装的应用程序列表（但是可以通过单击 Dock 底部的“显示应用程序”按钮从 Ubuntu Dock 访问）。例如，如果你想使用 Plank Dock。（to 校正：这里是什么意思呢）
|
||||
|
||||
显然，如果你安装了 Dash to Panel 扩展来使用它而不是 Ubuntu Dock，那么情况并非如此。因为 Dash to Panel 提供了一个按钮来访问多任务视图或已安装的应用程序。
|
||||
|
||||
根据你计划使用的 Dock 而不是 Ubuntu Dock，如果无法访问多任务视图，那么你可以启用 Activities Overview Hot Corner 选项，只需将鼠标移动到屏幕的左上角即可打开 Activities。访问已安装的应用程序列表的另一种方法是使用快捷键：`Super + A`。
|
||||
|
||||
如果要启用 Activities Overview hot corner，使用以下命令：
|
||||
```
|
||||
gsettings set org.gnome.shell enable-hot-corners true
|
||||
|
||||
```
|
||||
|
||||
如果以后要撤销此操作并禁用 hot corners，那么你需要使用以下命令：
|
||||
```
|
||||
gsettings set org.gnome.shell enable-hot-corners false
|
||||
|
||||
```
|
||||
|
||||
你可以使用 Gnome Tweaks 应用程序（该选项位于 Gnome Tweaks 的 `Top Bar` 部分）启用或禁用 Activities Overview Hot Corner 选项，可以使用以下命令进行安装：
|
||||
```
|
||||
sudo apt install gnome-tweaks
|
||||
|
||||
```
|
||||
|
||||
### 如何移除或禁用 Ubuntu Dock
|
||||
|
||||
下面你将找到 4 种摆脱 Ubuntu Dock 的方法，环境在 Ubuntu 18.04 下。
|
||||
|
||||
**方法 1: 移除 Gnome Shell Ubuntu Dock 包。**
|
||||
|
||||
摆脱 Ubuntu Dock 的最简单方法就是删除包。
|
||||
|
||||
这将会从你的系统中完全移除 Ubuntu Dock 扩展，但同时也移除了 `ubuntu-desktop` 元数据包。如果你移除 `ubuntu-desktop` 元数据包，不会马上出现问题，因为它本身没有任何作用。`ubuntu-meta` 包依赖于组成 Ubuntu 桌面的大量包。它的依赖关系不会被删除，也不会被破坏。问题是如果你以后想升级到新的 Ubuntu 版本，那么将不会安装任何新的 `ubuntu-desktop` 依赖项。
|
||||
|
||||
为了解决这个问题，你可以在升级到较新的 Ubuntu 版本之前安装 `ubuntu-desktop` 元包（例如，如果你想从 Ubuntu 18.04 升级到 18.10）。
|
||||
|
||||
如果你对此没有意见，并且想要从系统中删除 Ubuntu Dock 扩展包，使用以下命令：
|
||||
```
|
||||
sudo apt remove gnome-shell-extension-ubuntu-dock
|
||||
|
||||
```
|
||||
|
||||
如果以后要撤消更改，只需使用以下命令安装扩展：
|
||||
```
|
||||
sudo apt install gnome-shell-extension-ubuntu-dock
|
||||
|
||||
```
|
||||
|
||||
或者重新安装 `ubuntu-desktop` 元数据包（这将会安装你可能已删除的任何 ubuntu-desktop 依赖项，包括 Ubuntu Dock），你可以使用以下命令：
|
||||
```
|
||||
sudo apt install ubuntu-desktop
|
||||
|
||||
```
|
||||
|
||||
**选项2：安装并使用 vanilla Gnome 会话而不是默认的 Ubuntu 会话。**
|
||||
|
||||
摆脱 Ubuntu Dock 的另一种方法是安装和使用 vanilla Gnome 会话。安装 vanilla Gnome 会话还将安装此会话所依赖的其它软件包，如 Gnome 文档，地图，音乐，联系人，照片，跟踪器等。
|
||||
|
||||
通过安装 vanilla Gnome 会话，你还将获得默认 Gnome GDM 登录和锁定屏幕主题，而不是 Ubuntu 默认值，另外还有 Adwaita Gtk 主题和图标。你可以使用 Gnome Tweaks 应用程序轻松更改 Gtk 和图标主题。
|
||||
|
||||
此外，默认情况下将禁用 AppIndicators 扩展（因此使用 AppIndicators 托盘的应用程序不会显示在顶部面板上），但你可以使用 Gnome Tweaks 启用此功能（在扩展中，启用 Ubuntu appindicators 扩展）。
|
||||
|
||||
同样，你也可以从 vanilla Gnome 会话启用或禁用 Ubuntu Dock，这在 Ubuntu 会话中是不可能的（使用 Ubuntu 会话时无法从 Gnome Tweaks 禁用 Ubuntu Dock）。
|
||||
|
||||
如果你不想安装 vanilla Gnome 会话所需的这些额外软件包，那么这个移除 Ubuntu Dock 的这个选项不适合你，请查看其它选项。
|
||||
|
||||
如果你对此没有意见，以下是你需要做的事情。要在 Ubuntu 中安装普通的 Gnome 会话，使用以下命令：
|
||||
```
|
||||
sudo apt install vanilla-gnome-desktop
|
||||
|
||||
```
|
||||
|
||||
安装完成后，重启系统。在登录屏幕上，单击用户名，单击 `Sign in` 按钮旁边的齿轮图标，然后选择 `GNOME` 而不是 `Ubuntu`，之后继续登录。
|
||||
|
||||
|
||||
|
||||
如果要撤销此操作并移除 vanilla Gnome 会话，可以使用以下命令清除 vanilla Gnome 软件包，然后删除它安装的依赖项（第二条命令）：
|
||||
```
|
||||
sudo apt purge vanilla-gnome-desktop
|
||||
sudo apt autoremove
|
||||
|
||||
```
|
||||
|
||||
然后重新启动，并以相同的方式从 GDM 登录屏幕中选择 Ubuntu。
|
||||
|
||||
**选项 3：从桌面上永久隐藏 Ubuntu Dock，而不是将其移除。**
|
||||
|
||||
如果你希望永久隐藏 Ubuntu Dock，不让它显示在桌面上，但不移除它或使用 vanilla Gnome 会话，你可以使用 Dconf 编辑器轻松完成此操作。这样做的缺点是 Ubuntu Dock 仍然会使用一些系统资源，即使你没有在桌面上使用它，但你也可以轻松恢复它而无需安装或移除任何包。
|
||||
|
||||
Ubuntu Dock 只对你的桌面隐藏，当你进入叠加模式（Activities）时，你仍然可以看到并从那里使用 Ubuntu Dock。
|
||||
|
||||
要永久隐藏 Ubuntu Dock，使用 Dconf 编辑器导航到 `/org/gnome/shell/extensions/dash-to-dock` 并禁用以下选项（将它们设置为 false）：`autohide`, `dock-fixed` 和 `intellihide`。
|
||||
|
||||
如果你愿意，可以从命令行实现此目的，运行以下命令：
|
||||
```
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock autohide false
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock dock-fixed false
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock intellihide false
|
||||
|
||||
```
|
||||
|
||||
如果你改变主意了并想撤销此操作，你可以使用 Dconf 编辑器从 `/org/gnome/shell/extensions/dash-to-dock` 中启动 `autohide`, `dock-fixed` 和 `intellihide`（将它们设置为 true），或者你可以使用以下这些命令：
|
||||
```
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock autohide true
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock dock-fixed true
|
||||
gsettings set org.gnome.shell.extensions.dash-to-dock intellihide true
|
||||
|
||||
```
|
||||
|
||||
**选项 4：使用 Dash to Panel 扩展。**
|
||||
|
||||
[Dash to Panel][2] 是 Gnome Shell 的一个高度可配置面板，是 Ubuntu Dock 或 Dash to Dock 的一个很好的替代品（Ubuntu Dock 是从 Dash to Dock 克隆而来的）。安装和启动 Dash to Panel 扩展会禁用 Ubuntu Dock，因此你无需执行其它任何操作。
|
||||
|
||||
你可以从 [extensions.gnome.org][3] 来安装 Dash to Panel。
|
||||
|
||||
如果你改变主意并希望重新使用 Ubuntu Dock，那么你可以使用 Gnome Tweaks 应用程序禁用 Dash to Panel，或者通过单击以下网址旁边的 X 按钮完全移除 Dash to Panel: https://extensions.gnome.org/local/。
