When an output gets another resolution or scale, or a panel starts, grows or hides, the work area the layout fills is not the one komorebi tiled in, and nothing moved the windows until something else tiled them again. The bridge now sends the outputs, with their geometry and the work area of the desktop each shows, when KWin says they changed, when a dock window opens, closes or moves, and once a second, because KWin has no signal for the room a panel leaves. The table turns a monitor whose size or work area changed into a monitor notification. It is not a window event, since it is about no window: it goes to the monitor reconciliator, a thread that takes the window manager's lock as the threads of events and messages do, reads the size and work area of every monitor again and tiles the workspace in front of the focused monitor. Another monitor's windows keep their tiles until a retile. Every subscriber is notified of it, whether or not the state changed. vm-hotplug starts with the scale of one of two outputs changing under a running daemon. The VM library gets kde.outputs, which lists, disables, enables and scales outputs, for the commits that unplug and plug them.

komorebi for KDE
Overview
komorebi is a tiling window manager for KDE Plasma on Wayland. It decides where each window
goes, and KWin, the window manager of Plasma, moves and draws the windows.
komorebi is a daemon that runs in the background, and it is controlled with a CLI,
komorebic. Every komorebic command that asks something of the daemon is a message on its
socket, so anything that can run a command can drive komorebi: a terminal, a script, or a
program that binds keys, which is how a key is given an action.
komorebi aims to make as few modifications as possible to the operating system and desktop
environment by default. Users are free to make such modifications in their own configuration
files for komorebi, but these will always remain opt-in and off-by-default.
How it fits together
komorebi only responds to the events KWin reports about windows and to the messages it receives on a dedicated socket. komorebic is a CLI that writes messages on komorebi's socket. komorebi doesn't handle any keyboard or mouse inputs: a program that binds keys, such as the custom shortcuts in Plasma's System Settings, runs komorebic commands.

Getting started
Installing komorebi explains how to install the two programs: on NixOS with
the flake's module, which also starts komorebi with every Plasma session, and from source
anywhere else. Running komorebi explains how to start and stop the
daemon, ask it what it is doing and read its log.
Focusing windows explains how to give the focus to another window,
Moving windows how to move a window to another tile,
Stacking windows how to put windows on one tile, have the others wait
out of sight and bring one of them to the front,
Layouts how to change the arrangement of the tiles,
Resizing windows how to change the size of one (and
Resizing a tile by dragging its edge what a drag with the pointer does),
Floating windows how to take a window out of the layout and work with
the floating ones,
Monocle how to give one window the whole work area,
Maximizing windows how to have KWin maximize one,
Managing windows how to minimize, close and unmanage the focused
window and pause the daemon, and
Padding and work area offsets how to put gaps around the tiles
and keep parts of a monitor free of them.
Rules explains how to keep an application out of the layout, always tile it, or
float its windows.
Workspaces explains how each monitor shows one of its workspaces, which
are KWin's virtual desktops, and how to show another or move a window to one, and
Workspace rules how to have the windows of an application go to a
workspace by themselves.
Configuration explains komorebi.json, where komorebi looks for it and
how it is reloaded when it changes, Example configurations has one to
start from, and Application specific configuration
explains the files of rules for particular applications it can name.
Quickstart and autostart explains how to write an example
configuration, how to start komorebi with Plasma without the module, and how to replace the
configuration of a running daemon.
Borders explains how komorebi has KWin draw a border around each window,
Animation how it has KWin animate the windows going to their places, and
Transparency how it makes the windows that do not have the focus
see-through, Focus follows mouse how it has KWin give the focus
to the window under the pointer, Themes how a theme gives the borders their
colors, and Wallpapers how a monitor or a workspace shows a picture of its own,
and what it does to the borders.
Changing monitors explains what komorebi does when a monitor
changes size.
Subscribing to notifications explains how a program
such as a status bar follows what komorebi does. The CLI reference has a page
for every komorebic command, generated from its help.
Community
There is a Discord server available for
komorebi-related discussion, help, troubleshooting etc.
There is a YouTube
channel where I post
komorebi development videos, feature previews and release overviews. Subscribing
to the channel (which is monetized as part of the YouTube Partner Program) and
watching videos is a really simple and passive way to contribute financially to
the development and maintenance of komorebi.
There is an Awesome List which
showcases the many awesome projects that exist in the komorebi ecosystem.
Licensing for Personal Use
