Kröhnkite

AUR-git

A dynamic tiling extension for KWin.

Kröhnkite is mainly inspired by dwm from suckless folks, and aims to provide rock solid stability while fully integrating into KWin.

The name of the script is from mineral Kröhnkite; it starts with K and looks cool.

    • Multi-screen
    • Activities & Virtual desktop
    • Basic window management (minimize, fullscreen, switching, etc)
  • Multiple Layout Support
    • Tiling layout
    • Monocle layout
    • Desktop-friendly layouts (Spread, Stair)

Development Requirement

  • Typescript (tested w/ 3.1.x)
  • GNU Make
  • p7zip (7z)

Installation

You can install Kröhnkite in multiple ways.

Using .kwinscript package file

You can download krohnkite-x.x.kwinscript file, and install it through System Settings.

  1. Download the kwinscript file
  2. Open System Settings > Window Management > KWin Scripts
  3. Press Import KWin script... on the top-right corner
  4. Select the downloaded file

Alternatively, through command-line:

plasmapkg2 -t kwinscript -i krohnkite.kwinscript # installing new script
plasmapkg2 -t kwinscript -u krohnkite.kwinscript # upgrading existing script

To uninstall the package:

plasmapkg2 -t kwinscript -r krohnkite

Installing from Git repository

The simplest method would be:

make install
make uninstall # to uninstall the script

This will automatically build and install kwinscript package.

You can also manually build package file using:

make package

The generated package file can be imported from "KWin Script" dialog.

Simply Trying Out

Krohnkite can be temporarily loaded without installing the script:

make run
make stop

Note that Krohnkite can destroy itself completely once it is disabled, so no restart is required to deactivated it.

Enabling User-Configuration

It is reported that a manual step is required to enable user configuration of KWin scripts. This is a limitation of KWin scripting.

To enable configuration, you must perform the following in command-line:

mkdir -p ~/.local/share/kservices5/
ln -s ~/.local/share/kwin/scripts/krohnkite/metadata.desktop ~/.local/share/kservices5/krohnkite.desktop

A configuration button will appear in KWin Scripts in System Settings.

config button shown

To make changes effective, the script must be reactivate:

  1. On KWin Scripts dialog, untick Krohnkite
  2. Apply
  3. tick Krohnkite
  4. Apply

Tips

Setting Up for Multi-Screen

Krohnkite supports multi-screen setup, but KWin has to be configured to unlock the full potential of the script.

  1. Enable Separate Screen Focus under Window Management > Window Behavior > Multiscreen Behaviour
  2. Bind keys for global shortcut Switch to Next/Previous Screen (Recommend: Meta + , / Meta + .)
  3. Bind keys for global shortcut Window to Next/Previous Screen (Recommend: Meta + < / Meta + >)

Note: Separate Screen Focus appears only when multiple monitors are present.

Removing Title Bars

Breeze window decoration can be configured to completely remove title bars from all windows:

  1. System Setting > Application Style > Window Decorations
  2. Click Configure Breeze inside the decoration preview.
  3. Window-Specific Overrides tab > Add button
  4. Enter the followings, and press Ok:
    • Regular expression to match: .*
    • Tick Hide window title bar

Changing Border Colors

Changing the border color makes it easier to identify current window. This is convinient if title bars are removed.

  1. Open ~/.config/kdeglobals with your favorite editor
  2. Scroll down and find [WM] section
  3. Append the followings to the section:
    • frame=61,174,233: set the border color of active window to RGB(61,174,233)
    • inactiveFrame=239,240,241: set the border color of inactive window to RGB(239,240,241)
  4. You must restart your session to see changes. (i.e. re-login, reboot)

(Note: the RGB values presented here are for the default Breeze theme)
