KWin takes the windows of an output that goes to the outputs that are left and puts them where it likes, so komorebi's tiles for them were on a screen that was gone and the windows sat untiled where they landed. The monitor reconciliator now deals with a change in the set of monitors: the table announces it as a display connection change instead of a resize, and reconcile_display_change reads the monitors again, keeps each one that went (workspaces, layouts, paddings, offsets) in a cache, has the window manager move what was on it to the monitors that are left, and removes it. The move is WindowManager::evacuate_monitor, in the new reconcile module: each container and floating window goes to the workspace of the same number on the monitor that holds the middle of its window, or on the first monitor that is left when it is on none, and the workspaces that changed are tiled. A stack goes as one container, and a monocle and a maximized window come as ordinary containers. A monitor that is plugged in takes what was cached under its serial number id, less the windows that closed or that the window manager has elsewhere by now, so it comes back with its settings and none of the windows it had. A monitor komorebi never saw gets workspaces of its own, and when the compositor reports no output at all nothing is done. The workspace rules of a monitor that goes are dropped, and those of the workspaces of one that comes back apply again. komorebi.json fills the cache as well: a monitor that has the entry its display index preference names is kept with it, and so is the entry of each preference whose monitor is not connected, which that monitor takes when it is plugged in. vm-hotplug now sends two windows to the other monitor with komorebic, disables that output, enables it again and sends a window over once more.

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, is unplugged or is plugged in.
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.
