How to setup multiple monitors in sway
|
||||
======
|
||||
|
||||
![][1]
|
||||
|
||||
Sway is a tiling Wayland compositor which has mostly the same features, look and workflow as the [i3 X11 window manager][2]. Because Sway uses Wayland instead of X11, the tools to setup X11 don’t always work in sway. This includes tools like _xrandr_, which are used in X11 window managers or desktops to setup monitors. This is why monitors have to be setup by editing the sway config file, and that’s what this article is about.
|
||||
|
||||
## **Getting your monitor ID’s**
|
||||
|
||||
First, you have to get the names sway uses to refer to your monitors. You can do this by running:
|
||||
|
||||
```
|
||||
$ swaymsg -t get_outputs
|
||||
```
|
||||
|
||||
You will get information about all of your monitors, every monitor separated by an empty line.
|
||||
|
||||
You have to look for the first line of every section, and for what’s after “Output”. For example, when you see a line like “_Output DVI-D-1 ‘Philips Consumer Electronics Company’_”, the output ID is “DVI-D-1”. Note these ID’s and which physical monitors they belong to.
|
||||
|
||||
## **Editing the config file**
|
||||
|
||||
If you haven’t edited the Sway config file before, you have to copy it to your home directory by running this command:
|
||||
|
||||
```
|
||||
cp -r /etc/sway/config ~/.config/sway/config
|
||||
```
|
||||
|
||||
Now the default config file is located in _~/.config/sway_ and called “config”. You can edit it using any text editor.
|
||||
|
||||
Now you have to do a little bit of math. Imagine a grid with the origin in the top left corner. The units of the X and Y coordinates are pixels. The Y axis is inverted. This means that if you, for example, start at the origin and you move 100 pixels to the right and 80 pixels down, your coordinates will be (100, 80).
|
||||
|
||||
You have to calculate where your displays are going to end up on this grid. The locations of the displays are specified with the top left pixel. For example, if we want to have a monitor with name HDMI1 and a resolution of 1920×1080, and to the right of it a laptop monitor with name eDP1 and a resolution of 1600×900, you have to type this in your config file:
|
||||
|
||||
```
|
||||
output HDMI1 pos 0 0
|
||||
output eDP1 pos 1920 0
|
||||
```
|
||||
|
||||
You can also specify the resolutions manually by using the _res_ option:
|
||||
|
||||
```
|
||||
output HDMI1 pos 0 0 res 1920x1080
|
||||
output eDP1 pos 1920 0 res 1600x900
|
||||
```
|
||||
|
||||
## **Binding workspaces to monitors**
|
||||
|
||||
Using sway with multiple monitors can be a little bit tricky with workspace management. Luckily, you can bind workspaces to a specific monitor, so you can easily switch to that monitor and use your displays more efficiently. This can simply be done by the workspace command in your config file. For example, if you want to bind workspace 1 and 2 to monitor DVI-D-1 and workspace 8 and 9 to monitor HDMI-A-1, you can do that by using:
|
||||
|
||||
```
|
||||
workspace 1 output DVI-D-1
|
||||
workspace 2 output DVI-D-1
|
||||
```
|
||||
|
||||
```
|
||||
workspace 8 output HDMI-A-1
|
||||
workspace 9 output HDMI-A-1
|
||||
```
|
||||
|
||||
That’s it! These are the basics of multi monitor setup in sway. A more detailed guide can be found at <https://github.com/swaywm/sway/wiki#Multihead>.

如何在 sway 中设置多个显示器
|
||||
======
|
||||
|
||||
![][1]
|
||||
|
||||
Sway 是一种平铺式 Wayland 合成器，具有与 [i3 X11 窗口管理器][2]相同的功能、外观和工作流程。 由于 Sway 使用 Wayland 而不是 X11，因此就不能一如既往地使用设置 X11 的工具。这包括 `xrandr` 之类的工具，这些工具在 X11 窗口管理器或桌面中用于设置监视器。这就是为什么必须通过编辑 Sway 配置文件来设置显示器的原因，这就是本文的目的。
|
||||
|
||||
### 获取你的显示器 ID
|
||||
|
||||
首先，你必须获得 Sway 用来指代显示器的名称。你可以通过运行以下命令进行操作：
|
||||
|
||||
```
|
||||
$ swaymsg -t get_outputs
|
||||
```
|
||||
|
||||
你将获得所有显示器的相关信息，每个显示器都用空行分隔。
|
||||
|
||||
你必须查看每个部分的第一行，以及 “Output” 之后的内容。例如，当你看到 `Output DVI-D-1 'Philips Consumer Electronics Company'` 之类的行时，则该输出 ID 为 `DVI-D-1`。注意这些 ID 及其所属的物理监视器。
|
||||
|
||||
### 编辑配置文件
|
||||
|
||||
如果你之前没有编辑过 Sway 配置文件，则必须通过运行以下命令将其复制到主目录中：
|
||||
|
||||
```
|
||||
cp -r /etc/sway/config ~/.config/sway/config
|
||||
```
|
||||
|
||||
现在，默认配置文件位于 `~/.config/sway` 中，名为 `config`。你可以使用任何文本编辑器进行编辑。
|
||||
|
||||
现在你需要做一点数学。想象有一个网格，其原点在左上角。X 和 Y 坐标的单位是像素。Y 轴反转。这意味着，例如，如果你从原点开始，向右移动 100 像素，向下移动 80 像素，则坐标将为 `(100, 80)`。
|
||||
|
||||
你必须计算最终显示在此网格上的位置。显示器的位置由左上方的像素指定。例如，如果我们要使用名称为“HDMI1”且分辨率为 1920×1080 的显示器，并在其右侧使用名称为 “eDP1” 且分辨率为 1600×900 的笔记本电脑显示器，则必须在配置文件中键入 ：
|
||||
|
||||
```
|
||||
output HDMI1 pos 0 0
|
||||
output eDP1 pos 1920 0
|
||||
```
|
||||
|
||||
你还可以使用 `res` 选项手动指定分辨率：
|
||||
|
||||
```
|
||||
output HDMI1 pos 0 0 res 1920x1080
|
||||
output eDP1 pos 1920 0 res 1600x900
|
||||
```
|
||||
|
||||
### 将工作空间绑定到显示器上
|
||||
|
||||
与多个监视器一起使用 Sway 在工作区管理中可能会有些棘手。幸运的是，你可以将工作区绑定到特定的监视器，因此你可以轻松地切换到该显示器并更有效地使用它。只需通过配置文件中的工作区命令即可完成。例如，如果要绑定工作区 1 和 2 到显示器 “DVI-D-1”，绑定工作区 8 和 9 到显示器 “HDMI-A-1”，则可以使用以下方法：
|
||||
|
||||
```
|
||||
workspace 1 output DVI-D-1
|
||||
workspace 2 output DVI-D-1
|
||||
```
|
||||
|
||||
```
|
||||
workspace 8 output HDMI-A-1
|
||||
workspace 9 output HDMI-A-1
|
||||
```
|
||||
|
||||
就是这样。这就在 Sway 中多显示器设置的基础知识。可以在 <https://github.com/swaywm/sway/wiki#Wiki#Multihead> 中找到更详细的指南。
