The Calm Window Manager (CWM)

A minimalist floating window manager that also tiles

This repository showcases configuration of the Calm Window Manager (CWM) to keep the minimal asthetic, but at the same time make more practical.

CWM is a minimalist floating window manager:

x [x] float windows by default. x [x] snap any window into a corner, or edge of the screen. x [x] snap the floating windows into a tiling configuration. eg either x [x] horizontal master/stack, or vertical master/stack. x [x] retain gaps between the windows and the edge of the screen.

Also there is also a native application launcher that you can drive with the mouse or touchpad. eg use the keyboard to launch applications.

If the native application launcher is not to your liking, then it’s easy to add 3rd-party lanchers and status bars. eg Polybar.

As CWM doesn’t feature multi-monitor support, the ideal use-case is that you are just using a single monitor.

Screenshots of floating windows that are snapped into tiles

To create a few terminal windows, use alt+cntrl+enter for each terminal.

Without a Polybar:

For example, 4 floating windows can be snapped into tiles.

Then alt+cntrl+minus to tile the 4 windows, into a master window on the left and 3 stacked windows on the right.

Then in the tiled layout, to switch the active window (in the non-primary) with the primary position - simply alt-cntrl-minus again.

Use alt+cntrl+enter to create another terminal.

It will float on top of the 4 other windows for a total of 5 windows.

Then alt+cntrl+minus to restacck the 5 windows into the tiled layout with the focused window placed in the master position on the left.

So now 4 windows have been snapped into the stack on the right, and the focused window at that time was snapped into the master position on the left.

The tiled windows can also be restacked with alt+cntrl+shift+minus, so the master is now on top.

Screenshots of floating windows (without tiling)

Screenshots with the native application launcher

The application laucher can be run with a mouse click.

Or you may run applications from the shell. For example:

chromium-browser&

or to ignore any run-time errors:

chromium-browser > /dev/null 2>&1 &

Add the disown command to detach the application from the terminal:

chromium-browser > /dev/null 2>&1 & disown

As systemd is used, managing the host from the shell can also be achieved with the following commands:

systemctl suspend

systemctl reboot

systemctl poweroff

Installation and configuration of CWM

The official repo for CWM is here:

github.com/leahneukirchen/cwm

Most Linux distributions have the CWM in their repository. So installing CWM is extremely easy. For example, to install in Fedora:

sudo dnf install cwm

For Debian:

sudo apt-get install cwm

For Arch:

sudo pacman -S cwm

FreeBSD also has CWM in their repository, and is installed as follows:

sudo pkg install cwm

The ~/.cwmrc configuration file used in the screen shots is similar to this:

# CMS-r = restart
# these fonts are for the application launcher menu
#fontname fixed-13
fontname fixed-11

moveamount 10	# granularity of finest movement

Inspect the CWM manual for all the default key bindings:

man cwm

Then inspect the CWM configuration manual for the other possibilities for the ~/.cwmrc file:

man cwmrc

Applications

System information with Fastfetch

Also as an option, install Fastfetch for some bling when a terminal is started. The source is here: github.com/LinusDierheimer/fastfetch

Fastfetch is present in the Fedora repo:

sudo dnf install fastfetch

This is what Fastfetch looks like on Fedora.

However I can also use an actual image for the graphic, if I download a suitable image like as follows:

fedoraproject.org/wiki/File:Fedora_logo.png

Then I can call Fastfetch to use the image.

fastfetch --logo-type kitty --logo-width 60 --logo ~/Downloads/Fedora_logo.png

The virtual terminal with Urxvt

Urxvt is present in the Fedora repo:

sudo dnf install rxvt-unicode

My urxvt terminal is configured without scroll bars. Also use shift-pageup to scroll up, and shift-pagedown to scroll down. The +ssr parameter of urxvt turns off secondary screen scroll, so for example text inside the Vim editor will not be shown in the primary window after Vim has exited. The same setting is set with secondaryScroll.

Create a ~/.Xdefaults file for the configuration of the urxvt terminal. Place the following configuration in it:

URxvt.scrollBar: off
# turn off the secondary screen scrolling for a pager. eg less.
URxvt.secondaryScroll: off
URxvt.depth: 32
# black (0000/0000/0000) with no transparency (ffff)
# grey (1111/1111/1111) with no transparency (ffff)
URxvt.background: rgba:0000/0000/0000/ffff
URxvt.foreground: [100]grey
URxvt.font: xft:monospace:pixelsize=12
URxvt.geometry: 132x50
URxvt.visualBell: on

The virtual terminal with Kitty

Kitty is in the Fedora repo:

sudo dnf install kitty

My Kitty terminal is configured without scroll bars. Also use cntrl-shift-pageup to scroll up, and cntrl-shift-pagedown to scroll down. In Kitty, secondary screen scrolling is off by default.

Also define the font and font size you want to use with the Fish shell. In the config above I’m using FiraCode: github.com/tonsky/FiraCode

sudo dnf install fira-code-fonts

Kitty can autocreate a default configuration file in ~/.config/kitty/kitty.conf by using ctrl+shft+f2. Or you can maually create a configuration file yourself in the same location.

Then you can add configurations to the head of the file similar to as follows:

remember_window_size no
initial_window_width  1000
initial_window_height 1000
hide_window_decorations yes
background_opacity 0.9
dynamic_background_opacity yes
scrollback_fill_enlarged_window yes
focus_follows_mouse yes
# dnf install fira-code-fonts
font_family Fira Code Regular
font_size 10
enable_audio_bell no
visual_bell_duration 0.1
editor nvim

Terminal multiplexing with Tmux

Handy to have, so install it:

sudo dnf install tmux

Create a default ~/.tmux.conf file with the following contents:

# theme
#set -g @plugin 'catppuccin/tmux'
# ...alongside
set -g @plugin 'tmux-plugins/tpm'

#set -g @catppuccin_flavour 'latte' # or frappe, macchiato, mocha

set -g status-position top
# status bar
set -g status-style "bg=black"
set -ag status-style "fg=yellow"
# inactive status bar
set -g window-status-style bg=yellow
# active status bar
set -g window-status-current-style bg=red,fg=white

set -g mode-keys vi
set -g mouse

# Initialize TMUX plugin manager (keep this line at the very bottom of tmux.conf)
run '~/.tmux/plugins/tpm/tpm'

Terminal shell with Zsh

The Zsh shell is pretty plain out-of-the box but can be configured easily enough.

Unlike Fish, Zsh as a vim mode so you can escape and then use the vim key bindings to help you edit a command.

Install the Zsh shell as follows:

sudo dnf install zsh zsh-autosuggestions zsh-syntax-highlighting

We will use a Zsh plugin manager:

github.com/zap-zsh/zap

Install it as follows:

zsh <(curl -s https://raw.githubusercontent.com/zap-zsh/zap/master/install.zsh) --branch release-v1

Compared with Fish, there are less features out-of-the-box, so Zsh should be setup with a configuration file up-front. Create a default ~/.zshrc file with the following contents:

# Created by Zap installer
[ -f "${XDG_DATA_HOME:-$HOME/.local/share}/zap/zap.zsh" ] && source "${XDG_DATA_HOME:-$HOME/.local/share}/zap/zap.zsh"
plug "zsh-users/zsh-autosuggestions"
#plug "zap-zsh/supercharge"
#plug "zap-zsh/zap-prompt"
#plug "zsh-users/zsh-syntax-highlighting"
#plug "zsh-zsh/vim"

plug 'zdharma-continuum/fast-syntax-highlighting'
plug 'zsh-users/zsh-history-substring-search'

There are a number of native command prompt themes available, and they can be listed with :

prompt -p

An example of a basic Zsh command prompt theme (eg walters) is below:

An interactive shell with Fish

The Fish shell has syntax highlighting out-of-the box with a selection of prompts and colour themes. Install the Fish shell as follows:

sudo dnf install fish

The ~/.config/fish/config.fish file is like this:

if status is-interactive
    # Commands to run in interactive sessions can go here
    # add color to the less pager in Fish, not Bash does this differently using export.
    set -gx LESS_TERMCAP_mb (printf '\e[01;31m') # enter blinking mode - red
    set -gx LESS_TERMCAP_md (printf '\e[01;35m') # enter double-bright mode - bold, magenta
    set -gx LESS_TERMCAP_me (printf '\e[0m') # turn off all appearance modes (mb, md, so, us)
    set -gx LESS_TERMCAP_se (printf '\e[0m') # leave standout mode
    set -gx LESS_TERMCAP_so (printf '\e[01;33m') # enter standout mode - yellow
    set -gx LESS_TERMCAP_ue (printf '\e[0m') # leave underline mode
    set -gx LESS_TERMCAP_us (printf '\e[04;36m') # enter underline mode - cyan
end
#Note - same what may be found in a Bash configuration file except the $ is removed.

#Add your favourite keyboard layout here for X11
#setxkbmap -layout us -variant <name>

# Now it's your choice of fastfetch for every terminal
#fastfetch
# or fastfetch just for the 1st terminal (fish syntax)
set -l LIVE_COUNTER $(ps a -o tty $(pgrep $(echo $TERM)) | uniq --unique | wc -l)
if [ $LIVE_COUNTER -eq 1 ]
     fastfetch
end

The theme and prompt can also be selected from the native configurations. Display a list of Fish themes with:

fish_config theme show

Then choose a Fish theme like this:

fish_config theme choose 'ayu Dark'
fish_config theme save 'ayu Dark'

Similarly display a list of Fish prompts with:

fish_config prompt show

And choose a Fish prompt like this:

fish_config prompt choose nim
fish_config prompt save

An example of the 'ayu Dark' theme with a 'nim' prompt is below:

If you are running a job in the background then it will be shown.

When no jobs are present then the normal prompt returns.

Window transparency with Picom

Transparency in the terminal is enabled in the terminal, but the transparency itself is performed by Picom:

sudo dnf install picom

Status bar with Polybar

Status bar can be provided by Polybar:

sudo dnf install polybar

In the Fedora repo there is an example config file installed by default: /usr/share/doc/polybar/examples/config.ini

However this file can be copied to: ~/.config/polybar/config.ini

mkdir ~/.config/polybar/
cp /usr/share/doc/polybar/examples/config.ini ~/.config/polybar/config.ini

By default, this is what it looks like (need the prerequisite fonts installed - see below)

However, the bar is easy to customise to your liking, and edit the configuration file to remove any components that you don’t want to use.

For Fedora, you may need to install the right fonts (eg siji, and NotoColorEmoji) for the Polybar config file. Also need the xset app for the siji font below:

sudo dnf install xset

Then follow the instructions in github to install the siji font:

github.com/stark/siji

Now ensure the Polybar config.ini file refers to the google-noto-emoji font:

font-0 = fixed:pixelsize=10;1
;font-1 = unifont:fontformat=truetype:size=8:antialias=false;0
;then edit the font-1 line in the config look like this (uses the google-noto-emoji font)
font-1 = NotoColorEmoji:fontformat=truetype:scale=8;0
font-2 = siji:pixelsize=10;1

Then run the example bar with:

polybar example&

Or place the above command in the CWM configuration file (shown below).

Now the Polybar will look something like this:

Tiled windows with a Polybar (top right corner):

An modified version of the example Polybar, with the bar at 50% of the screen width, is shown below:

Text editing with Neovim and Lua

Neovim can be thought of as an enhanced Vim editor, with the advantage that the Lua language can be used for configuration.

Install Neovim in Fedora like this:

sudo dnf install neovim

Neovim can reuse a Vim configuration file (with Vimscript), but for those that want to use Lua, then the starting point is to do the following steps.

Create a Lua directory for Neovim:

mkdir -p ~/.config/nvim/lua

Now create a settings file using Lua in ~/.config/nvim/lua/settings.lua The settings file will be based on your current vim.init file, but now the Lua syntax will be used instead.

local o = vim.o
local wo = vim.wo
local bo = vim.bo

-- global options
o.termguicolors = true
o.ignorecase = true

-- highlight the vertical split, and the whole line the cursor is on.
vim.api.nvim_exec(

    highlight vertsplit cterm=none gui=none
    highlight cursorline guibg=Grey20

)

-- Short-hand for vim.api.nvim_exec
-- set the format for NETRW
vim.cmd([[
    let g:netrw_liststyle=3

]])

-- for highlight on yank
vim.cmd([[
    au TextYankPost * silent! lua vim.highlight.on_yank {higroup="IncSearch", timeout=150}
]])


--set the colorscheme from the core selections.
--vim.api.nvim_command('colorscheme darkblue')
-- https://github.com/neanias/everforest-nvim
vim.cmd([[colorscheme everforest]])

Now create a reference to the settings file in ~/.config/nvim/init.lua file like this:

-- lua/plugins.lua
require('plugins')
require('packer')
require('neoscroll').setup()
require'shade'.setup({
  overlay_opacity = 50,
  opacity_step = 1,
  keys = {
    brightness_up    = '<C-Up>',
    brightness_down  = '<C-Down>',
    toggle           = '<Leader>s',
  }
})
require('base16-colorscheme')

-- https://github.com/neanias/everforest-nvim
require("everforest").setup({
  -- Controls the "hardness" of the background. Options are "soft", "medium" or "hard".
  -- Default is "medium".
  background = "hard",
  -- How much of the background should be transparent. Options are 0, 1 or 2.
  -- Default is 0.
  --
  -- 2 will have more UI components be transparent (e.g. status line
  -- background).
  transparent_background_level = 0,
  -- Whether italics should be used for keywords, builtin types and more.
  italics = false,
  -- Disable italic fonts for comments. Comments are in italics by default, set
  -- this to `true` to make them _not_ italic!
  disable_italic_comments = false,
})

-- Environment settings in lua/settings.lua
require('settings')

Now edit the ~/config/nvim/lua/plugins.lua

-- automatically install and set up packer.nvim on any machine you clone your configuration to
local fn = vim.fn
local install_path = fn.stdpath('data')..'/site/pack/packer/start/packer.nvim'
if fn.empty(fn.glob(install_path)) > 0 then
  packer_bootstrap = fn.system({'git', 'clone', '--depth', '1', 'https://github.com/wbthomason/packer.nvim', install_path})
end

-- configure Neovim to automatically run :PackerCompile whenever plugins.lua is updated with an autocommand:
vim.cmd([[

  augroup end
]])

return require('packer').startup({function()
  -- My plugins here
  -- use 'foo1/bar1.nvim'
  -- use 'foo2/bar2.nvim'

  -- Packer can manage itself
  use {'wbthomason/packer.nvim'}

  -- Neoscroll: a smooth scrolling neovim plugin written in lua
  -- https://github.com/karb94/neoscroll.nvim
  use {'karb94/neoscroll.nvim'}

  -- Shade is a Neovim plugin that dims your inactive windows, making it easier to see the active window at a glance.
  -- https://github.com/sunjon/Shade.nvim
  use {'sunjon/shade.nvim'}

  -- https://github.com/RRethy/nvim-base16
  use {'RRethy/nvim-base16'}

  -- https://github.com/neanias/everforest-nvim
  use({
  "neanias/everforest-nvim",
  -- Optional; default configuration will be used if setup isn't called.
  config = function()
    require("everforest").setup()
  end,
  })

-- Automatically set up your configuration after cloning packer.nvim
  -- Put this at the end after all plugins
  if packer_bootstrap then
    require('packer').sync()
  end
end,
-- use a floating window with single borders for command outputs
config = {
  display = {
    --open_fn = require('packer.util').float,
	open_fn = function()
      return require('packer.util').float({ border = 'single' })
    end
  }
}
})

Now install and resync the plugin like this: :PackerInstall :PackerSync :PackerCompile

The following screenshot uses the everforest color scheme.

PDF document viewer with Zathura

It’s possible to view PDFs with your browser, but a dedicated PDF viewer can be more convenient.

sudo dnf install zathura zathura-plugins-all
sudo dnf install zathura-fish-completion

Some of the key bindings are the same as Vim, with the basics as:

j = down
k = up
g = top of document
G = bottom of document
minus = zoom in
plus = zoom out
equals = original size
q = quit

Viewing a PDF is as easy as:

zathura <name of pdf>

Other applications

Use of other packages can be seen in the screenshots, and they are:

chromium - browser
exa - a modern replacement for ls
feh - wallpaper launcher
xclip - copy between the clipboard and the primary selection
git - version control
sysstat - for the sar utility
redshift - adjusts the color temperature of your screen
flameshot - for screenshots

Install those from DNF

sudo dnf install chromium exa feh xclip vim-X11 git sysstat redshift flameshot

So using xsel or xclip you can copy selections as follows:

xsel -o --primary| xsel -i --clipboard

xclip -o -selection primary| xclip -i -selection clipboard

Flameshot can be used like this:

flameshot gui

If you are using a laptop, then the touchpad may not have full functionality. For example, a drag selection is possible, but a double-tap selection is not. So to enable a double-tap selection, create the following file as the root user: /etc/X11/xorg.conf.d/10-touchpad.conf

Section "InputClass"
    Identifier "tap-by-default"
    Driver "libinput"
    Option "Tapping" "on"
EndSection

Rectify any screen tearing and freezing

If you are using the native X11 drivers for your GPU, then it’s possible you may encounter abnormal video. The same problems may not exist with the vendor supplied drivers.

For the native X11 drivers, you may experience screen tearing and freezing for the Intel GPU that you’re using. If so, then try the following.

Create the following file as the root user: /etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    # stop screen tearing
    Option "TearFree" "true"
    Option "TripleBuffer" "true"
    # stop screen freezing
    Option "DRI" "2"
EndSection
