运行sway窗口管理器

安装

apt安装sway
sudo apt install sway wofi

Kali Linux 默认使用的图形登陆管理器可以自动管理 sway 的登陆会话,并且会正确设置 wayland显示服务器协议 显示服务,所以只需要在图形登陆管理器中选择 sway 登陆就是这个平铺WM了。

我最终改为 Raspberry Pi OS 工作环境,采用精简安装,没有安装窗口管理器。那么最方便自动启动 sway 的方法是在环境配置(例如 ~/.zshrc )添加以下内容:

复制sway个人配置
if [ -z $DISPLAY ] && [ "$(tty)" = "/dev/tty1" ]; then
  exec sway
fi

这样启动到字符终端就会立即启动 sway ,而 sway 图形管理器退出后会立即再次启动 tty ,也就是再次自动登陆到 sway

使用设置

  • sway窗口管理器使用fcitx5 输入法可以非常完美使用中文,但是需要注意

    • 默认 foot 终端虽然能够输入中文,但是无法现实中文候选字词,所以改为 qterminal (默认 Kali Linuxxfce 配套终端模拟器,轻量级且功能完备)就可以正常输入中文

    • chromium 无法输入中文(显示运行没有问题),不过好在 firefox 使用中文输入正常,所以我同时采用这2个浏览器取长补短

  • 配置定制,先将全局配置复制到个人目录下:

复制sway个人配置
mkdir -p ~/.config/sway
cp /etc/sway/config ~/.config/sway/
  • 我的配置:

sway个人配置
# Default config for sway
#
# Copy this to ~/.config/sway/config and edit it to your liking.
#
# Read `man 5 sway` for a complete reference.

### Variables
#
# Logo key. Use Mod1 for Alt.
# 我尝试过使用 Alt ,但是有些应用默认内置了 Alt 作为快捷键,可能会有冲突
set $mod Mod4

# Home row direction keys, like vim
# 结合 $mod + 移动键可以快速在4个方向上移动聚焦窗口
set $left h
set $down j
set $up k
set $right l

# Your preferred terminal emulator
# 将默认foot终端修改成qtermianl可以支持fcitx中文输入
#set $term foot
set $term qterminal

# Your preferred application launcher
# Note: pass the final command to swaymsg so that the resulting window can be opened
# on the original workspace that the command was run on.
set $menu dmenu_path | dmenu | xargs swaymsg exec --

include /etc/sway/config-vars.d/*

### Output configuration
#
# Default wallpaper (more resolutions are available in /usr/share/backgrounds/sway/)
output * bg /usr/share/backgrounds/sway/Sway_Wallpaper_Blue_1920x1080.png fill
#
# Example configuration:
#
#   output HDMI-A-1 resolution 1920x1080 position 1920,0
#
# You can get the names of your outputs by running: swaymsg -t get_outputs

### Idle configuration
#
# Example configuration:
#
# exec swayidle -w \
#          timeout 300 'swaylock -f -c 000000' \
#          timeout 600 'swaymsg "output * dpms off"' resume 'swaymsg "output * dpms on"' \
#          before-sleep 'swaylock -f -c 000000'
#
# This will lock your screen after 300 seconds of inactivity, then turn off
# your displays after another 300 seconds, and turn your screens back on when
# resumed. It will also lock your screen before your computer goes to sleep.

exec_always fcitx5 -d --replace

### Input configuration
#
# Example configuration:
#
#   input "2:14:SynPS/2_Synaptics_TouchPad" {
#       dwt enabled
#       tap enabled
#       natural_scroll enabled
#       middle_emulation enabled
#   }
#
# You can get the names of your inputs by running: swaymsg -t get_inputs
# Read `man 5 sway-input` for more information about this section.

  • GTK应用默认启用wayland所以无需配置,但是QT5应用应用需要设置环境变量引导程序启用Wayland - 配置 /etc/environment 添加

QT5应用环境变量 /etc/environment
QT_QPA_PLATFORM=wayland

问题和解决方法

由于 sway 使用了前沿的 wayland显示服务器协议 图形显示服务,所以有些应用可能无法native支持,或者需要特殊运行参数

  • firefox可以直接运行在纯 waylandsway 环境

  • chromium需要指定参数(上文中 sway 配置中采用快捷键绑定启动参数):

    chromium --enable-features=UseOzonePlatform --ozone-platform=wayland
    
  • 配置linux系统级代理 但是chromium不生效,所以在启动参数上添加 --proxy-server 参数,所以chromium参数如下( 参考 Configure Proxy for Chromium and Google Chrome From Command Line on Linux ):

    chromium --enable-features=UseOzonePlatform --ozone-platform=wayland --proxy-server="http://192.168.10.9:3128"
    

如果使用socks5代理,则类似参数 --proxy-server="socks5://127.0.0.1:1080" 。更为方便的方法是使用 结合SSH Tunnel和AutoProxy插件翻墙 方案中的 Proxy SwitchyOmega

  • chromium不能使用 小企鹅输入法fcitx 输入中文,但是firefox可以,暂时采用双浏览器还没有解决这个问题

  • audacious 启动需要传递 -Q 参数(QT界面),使用默认的 -G (GTK界面)无法打开display

  • 音乐播放需要使用 MPD(Music Player Daemon) 服务,特别需要注意默认配置不能使用HDMI输出,需要定制 mpd.conf 配置

  • VLC可能是最好的视频播放软件,但是我的 sway - i3兼容Wayland compositor 环境运行在 树莓派Raspberry Pi 400 需要配置正确的音频设备 ALSA内核声音子系统 以及正确的视频设备 wayland显示服务器协议 :

    • 音频输出输出:

      • Output module: ALSA audio output

      • Device: bcm2835 HDMI 1,bcm2835 HDMI 1 Default Audio Device

    • 视频设备输出:

      • Output: Wayland shared memory video output

      • Fullscreen Video Device: HDMI-A-1

这是我的 树莓派Raspberry Pi 400 硬件环境配置,你的设备可能不同,请尝试对应的硬件设备配置。

  • 浏览器

    • qutebrowser 是基于QT5的使用vim键盘方式控制浏览器

    • Konqueror 是KDE默认浏览器,功能包含了浏览器和文件管理器功能: 缺点是太沉重了,如果不是使用KDE环境则过于复杂

    • Falkon 也是KDE开发的浏览器,功能精简,经过验证我发现这个浏览器兼容性好(因为引擎就是chromium的精简QTWebkit核心)而且占用资源少,是理想的 sway - i3兼容Wayland compositor 配套浏览器

    • Otter Browser 基于QT5的继承Opera 12的浏览器,但是这个浏览器没有收录在软件仓库,需要源代码编译安装,太过折腾

最终我在 移动开发:树莓派开发环境构建 中采用 Falkon 作为主力浏览器

$mod + d 不能唤起菜单

  • 单独在终端执行 dmenu 命令提示:

    cannot open display
    

这说明没有支持 native wayland 图形显示服务( dmenu 可以运行在 XWayland 环境 )

参考 arch linux: sway : sway wiki 提供 已知兼容sway应用启动器列表 ,网上有人推荐使用 bemenu ,并且Arch Linux案例也推荐使用 bemenu 。不过,arch linux的仓库是直接提供 bemenu ,但是 kali linux(ubuntu) 软件仓库只提供 wofi ,其他启动器需要自己编译

假如使用 bemenu 在修订 ~/.config/sway/config (我没有尝试)

j4-dmenu-desktop --dmenu='bemenu -i --nb "#3f3f3f" --nf "#dcdccc" --fn "pango:DejaVu Sans Mono 12"' --term='termite'

我使用系统自带 wofi

sudo apt install wofi

然后配置设置(注释掉默认的 $menu 配置):

#set $menu dmenu_path | dmenu | xargs swaymsg exec --
set $menu wofi --show=drun --lines=5 --prompt=""
  • 重新加载 sway 配置: Shift + mod4 + c ,然后就可以通过 mod4 + d 加载应用加载器,非常类似macOS环境的Spotlight搜索功能加载应用程序。

Firefox

在 Firefox 的 about:supprt 页面可以观察Firefox是否已经完全切换到 native wayland :

  • Window Protocol 应该是 wayland ,如果显示 xwayland 则建议设置环境变朗 set -x MOZ_ENABLE_WAYLAND 1 然后在启动Firefox观察

Chroium

配置 ~/.config/chromium-flags.conf 添加以下行:

--enable-features=UseOzonePlatform
--ozone-platform=wayland

可以使chromium 运行在wayland模式。
