Preface

You don’t really need a versatile desktop suite, just a window manager can get your job done, less components, less bugs, more efficient.

If you prefer keyboard navigation, then use Sway, if you prefer using mouse to point and click, then then Labwc.

This guide is distro independent, tested on Arch and Fedora.

Sway Labwc

Install Sway, Labwc and other essential packages:

sway swaylock swaybg labwc wl-clipboard wmenu mako wob kanshi grim wev
xdg-desktop-portal-gtk

xdg-desktop-portal:
xdg-desktop-portal-gtk : necessary component for e.g. file chooser.
wl-clipboard : necessary for ctrl-c ctrl-v function.
wmenu : menu for launching apps and running commands.
mako : desktop notification.
wob : indicator bar for volume or brightness.
kanshi: dynamic output configuration.
grim screenshot tool for wayland.
wev : detect key name, for configuring keybindings.
sway-contrib : grim helper for partial screenshot.

We won’t discuss their configurations in detail, you can refer to the official documentations. Instead, I will show you some basic ideas about how I use them.

For Sway, since it is keyboard driven and tiling, I bind Super + 1/2/3/4/5/6/7/8/9/0, Super + q/w/e/r/t/y/u/i/o/p, Super + z/x/c/v/b/n/m to corresponding workspaces, and Super + Shift + ... to move windows into them. Then I use apps in maximum mode, one window per workspace for most of time. In this way, I need to track which workspaces are in use, so I choose built-in swaybar to do this work.

Unfortunately, swaybar is lacking system tray support. But I think it’s not a big problem, you don’t really need it, if you want some apps running in the background, just throw them into a dedicated workspace in the corner and forget, done.

For Labwc, there isn’t much to say, all the actions can be invoked from the right-click context menu. Since it’s mouse driven and floating, single workspace is enough, you just use Alt + Tab to switch between windows.

That’s all. Just keep it simple and clean.

Terminal

I prefer foot and alacritty, both are simple and fast terminal emulators.

File Manager

Nautilus aka GNOME/Files is a good one.

Packages for Arch and Fedora: nautilus ifuse gvfs gvfs-mtp gvfs-gphoto2 gvfs-afc

GVFS is for auto mounting usb drives, mobile devices and trash functionality.

ifuse gvfs-gphoto2 gvfs-afc are for iOS device support. There’s a glitch after pluging in the iOS device, you can only see the virtual filesystem for iOS apps, not for photos. To fix this, first open that virtual filesystem for apps, the URL in the address bar is like afc://<URL>:3, change :3 to :1 and press Enter, now you switch to the virtual filesystem for photos.

Set nautilus as default file manager:

xdg-mime default org.gnome.Nautilus.desktop inode/directory

When you use “Open With” to open file with some app, it will invoke app’s desktop entry, when the app is a command line app, there’s a key-value Terminal=true in its desktop entry file, for example, you want to open a text file with neovim, Nautilus detected this ‘Terminal=true’ and would try to run it in the “default terminal”, then how does this default terminal being determined? I found it from gsettings:

(user)$ gsettings get org.gnome.desktop.default-applications.terminal exec

It returns xdg-terminal-exec, this is the right executable, but this gsettings key-value is not the one which affect “Open With” behavior. I’ve done some experiments, found it seems hard coded, Nautilus always try to invoke xdg-terminal-exec even when I changing this exec value to another executable. Fortunately, xdg-terminal-exec is maintained as a seperated package, we could choose not to install it and write our own for simplicity, just create a script /usr/local/bin/xdg-terminal-exec with:

#!/bin/bash
foot "${@}"
# alacritty -e "${@}"

There’s another missing feature when using Nautilus out of GNOME, which is “open terminal here”, and it can be implemented via Nautilus’s built-in function Custom Scripts, but there’re some inconvenience in this way, you need to right click on the folder, select the script from context menu, which means you need to take this action in the parent folder, which is counter-intuitive for “open terminal here”. Normally we want to do this by right-clicking on the blank inside the target folder, so “Custom Scripts” is not a good choice here, instead, I recommend using “Open With” to implement this function, here’s how:

Create /usr/local/bin/open-terminal-here.sh with:

#!/bin/bash
abspath=$(realpath "${1}")
if [[ -d "${abspath}" ]]; then
    foot -D "${abspath}"
    # alacritty --working-directory "${abspath}"
else
    foot
    # alacritty
fi

Create ~/.local/share/applications/open-terminal-here.desktop with:

[Desktop Entry]
Name=Open Terminal Here
Exec=open-terminal-here.sh %F
Icon=foot
Terminal=false
Type=Application
Categories=System;TerminalEmulator;
Keywords=shell;prompt;command;commandline;
MimeType=inode/directory;

Apply change:

(user)$ update-desktop-database ~/.local/share/applications

You may also want to disable “Recent Files”:

(user)$ gsettings set org.gnome.desktop.privacy remember-recent-files false

Zip/Unzip

I recommend PeaZip as GUI archive manager.

Install dependency package qt6pas first. Then download peazip tarball and extract to e.g. /data/apps/peazip, use /data/apps/peazip/res/share/batch/freedesktop_integration/peazip.desktop as template to create 2 desktop entries in ~/.local/share/applications/:

peazip-extract-newfolder.desktop:

Name=PeaZip Extract Smart
Exec=/data/apps/peazip/peazip -ext2folder %F
Icon=/data/apps/peazip/res/icons/peazip

peazip-add-archive.desktop:

Name=PeaZip Add Archive
Exec=/data/apps/peazip/peazip -add2archive %F
Icon=/data/apps/peazip/res/icons/peazip
MimeType=application/octet-stream;

Apply change:

(user)$ update-desktop-database ~/.local/share/applications

Ref: Desktop entries

Also recommend installing 7zip package for zip/unzip in command line.

Policykit

Tools like Ventoy need polkit to evaluate privilege.

Packages for Arch and Fedora: polkit mate-polkit

The executable needs to be added into autostart script for Sway and Labwc.

Excutable for Arch: /usr/lib/mate-polkit/polkit-mate-authentication-agent-1
Excutable for Fedora: /usr/libexec/polkit-mate-authentication-agent-1

Input Method

For input method, I use Fcitx5 and RIME. Here is my RIME configs for Wubi86: rime-wubi86s.

Packages for Arch and Fedora: fcitx5 fcitx5-gtk fcitx5-qt fcitx5-configtool fcitx5-rime

Add environment variables to .bashrc, then relogin user:

export QT_IM_MODULE=fcitx
export XMODIFIERS=@im=fcitx

The launching command fcitx5 -d -r needs to be added into autostart script for Sway and Labwc.

GTK Theme

For GTK 4:

(user)$ gsettings set org.gnome.desktop.interface color-scheme prefer-dark
(user)$ gsettings set org.gnome.desktop.interface color-scheme default

For GTK 3, install gnome-themes-extra package:

(user)$ ls /usr/share/themes
(user)$ gsettings set org.gnome.desktop.interface gtk-theme Adwaita-dark
(user)$ gsettings set org.gnome.desktop.interface gtk-theme Adwaita

Ref: GTK#Basic theme configuration , GTK 3 settings on Wayland

Qt Theme

IMHO, if you’re not intended to use KDE desktop environment, then avoid choosing KDE replated components, since they are tightly coupled with the KDE framework, lots of dependencies would be installed even for a very simple package like breeze-icons, which is annoying. LXQt is in a similar situation.

The original qt6ct is archived, although there is a successor, I decided not dealing with KDE apps anymore. For other independent Qt apps, they usually work well by default, no need tools like qt5ct/qt6ct get involved.

Icon Theme

Install basic icons theme: hicolor-icon-theme.

If you want to use Breeze icon theme, just download the repo manually:

(user)$ git clone https://github.com/KDE/breeze-icons ~/Downloads
(user)$ cp -r ~/Downloads/breeze-icons/icons ~/.local/share/icons/Breeze
(user)$ cd ~/.local/share/icons/Breeze
(user)$ cat breeze.theme.in commonthemeinfo.theme.in > index.theme

Change GTK icon theme

(user)$ ls /usr/share/icons
(user)$ gsettings set org.gnome.desktop.interface icon-theme Breeze

Other Apps

Brave disable Crypto and AI related components via Group Policy:

Create /etc/brave/policies/managed/brave-policy.json :

{
  "BraveAIChatEnabled": true,
  "BraveRewardsDisabled": true,
  "BraveWalletDisabled": true,
  "BraveNewsDisabled": true,
  "BraveTalkDisabled": true,
  "BraveVPNDisabled": 1
}

Visit brave://policy from address bar to check the effect.
