需先装好可用的 Plasma 环境以及 i3 或 i3-gaps,否则新会话无法启动;i3 配置里杀掉 Plasma 壁纸窗口的规则按英文标题匹配,非英文环境需用 wmctrl 查出实际窗口名替换;picom 的模糊效果需用 git 版本构建,发行版自带版本可能不支持。

在 KDE Plasma 之上运行 i3 窗口管理器,不依赖任何集成包,附完整配置指南
一套在 KDE Plasma 之上运行 i3 窗口管理器的配置方案,包含 Debian Sid 环境下的 dotfiles、脚本和踩坑记录,适合想兼顾平铺效率与桌面完整性的用户。
核心能力
- 新建 plasma-i3.desktop 会话文件,在登录管理器里增加 Plasma i3 会话
- 用 for_window 规则把 Plasma 弹窗、面板和对话框设为浮动,避免被平铺
- 可移除 i3bar,改用 Plasma 自带状态栏与 Pager 组件显示工作区
- 用 feh 或 nitrogen 设置桌面壁纸,picom 提供 V Sync 与透明模糊效果
容易踩的坑
暂无 release 数据(可能没有发版,或尚未同步)。

dotfiles
Here you can find the configuration files and a detailed guide to use the i3 window manager on the top of KDE Plasma desktop environment without relying on any kind of "integration" packages.
...as always: If this eats your cat or starts a global thermonuclear war, you are on your own.

The rest of my configuration and dotfiles are described and documented in config.md.
Requirements
You will need the following things:
- A working Plasma environement (just follow the instructions on how to install Plasma for your distro);
i3ori3-gaps;fehornitrogenfor setting the desktop background.
And optionally:
- A compositor like
picom, for V Sync and transparency effects. You may want a version built from their git repo for stuff like blurring.
Create a new X Session file
As root (or with sudo) create a new file called plasma-i3.desktop in /usr/share/xsessions/ with the following content:
[Desktop Entry]
Type=XSession
Exec=env KDEWM=/usr/bin/i3 /usr/bin/startplasma-x11
DesktopNames=KDE
Name=Plasma i3 session
Comment=Plasma i3 session
This will add a new available session in your login manager.
Add some stuff in the i3 configuration
Next, add the following lines in your i3 configuration (~/.config/i3/config):
# Kill the wallpaper window set by Plasma*
for_window [title="Desktop — Plasma"] kill; floating enable; border none
# Set Plasma dialogs and pop ups as floating so they won't get tiled
for_window [window_role="pop-up"] floating enable
for_window [window_role="task_dialog"] floating enable
for_window [class="systemsettings"] floating enable
for_window [class="plasmashell"] floating enable;
for_window [class="Plasma"] floating enable; border none
for_window [title="plasma-desktop"] floating enable; border none
for_window [class="krunner"] floating enable; border none
for_window [class="Kmix"] floating enable; border none
for_window [class="Klipper"] floating enable; border none
for_window [class="Plasmoidviewer"] floating enable; border none
for_window [class="plasmashell" window_type="notification"] border none, move right 700px, move down 450px
no_focus [class="plasmashell" window_type="notification"
# Set other stuff as floating
for_window [class="(?i)*nextcloud*"] floating disable
# Set the desktop background
exec --no-startup-id feh --bg-scale <PATH_TO_YOUR_WALLPAPER>
# Start the compositor daemonizing it (-b) and enabling shadows (-c)
exec_always --no-startup-id picom -cb
*The first line needs to be adapted if your Plasma language is not english. Use a tool like wmctrl to get the name of the window spawning when you login and replace the value in the i3 configuration file.
From this point on, you can logout and relog with the newly created session.
Optional final tuning
Remove i3bar
You may want to remove the lines related to the i3bar if you plan on keeping the Plasma status bar.
The Plasma "Pager" widget shows the i3 workspaces nicely, just be sure to have "Workspace name" instead of "Workspace number" in its configuration.
Disable "Activities" shortcut
Disable the Meta+Q shortcut from Plasma Settings > Category Workspace > Shortcuts > Category System Services > Plasma > Activities
Transparency and blurring
This can be configured per-window or per-application in the compositor settings. See picom.
The git version of picom has also dual_kawase as blur method.
