Debian Desktop Personalization

Introduction​

Debian is known for its stability and versatility, but the default desktop environment can look rather plain. Personalization allows you to transform your Debian desktop into a workspace that not only looks appealing but also enhances your productivity. This guide will walk you through various aspects of desktop personalization in Debian, covering everything from changing themes and icons to installing extensions and configuring system behaviors.

Whether you're using GNOME, KDE, Xfce, or another desktop environment, these customization techniques will help you create a desktop that feels uniquely yours.

Desktop Environments in Debian​

Before diving into personalization, it's important to understand which desktop environment you're using, as customization options vary between them.

Common Desktop Environments in Debian​

  • GNOME: Modern, minimalistic interface with a focus on simplicity
  • KDE Plasma: Feature-rich, highly customizable environment
  • Xfce: Lightweight, traditional desktop experience
  • Cinnamon: Feature-rich with a traditional layout
  • MATE: Fork of GNOME 2, offering a classic experience

To check your current desktop environment, run:

bash
echo $XDG_CURRENT_DESKTOP

You can install multiple desktop environments on the same system. For example, to install KDE Plasma:

bash
sudo apt update
sudo apt install kde-plasma-desktop

Basic Theme Customization​

Changing Themes in GNOME​

GNOME offers a straightforward way to change themes through the Settings application.

  1. Install GNOME Tweaks:
bash
sudo apt update
sudo apt install gnome-tweaks
  1. Launch GNOME Tweaks from your applications menu
  2. Navigate to the "Appearance" section
  3. Here you can change:
    • Applications (GTK) theme
    • Cursor theme
    • Icon theme
    • Shell theme (requires GNOME Shell extensions)

Installing New Themes​

Themes are typically installed to either:

  • System-wide location: /usr/share/themes/
  • User-specific location: ~/.themes/

To install a theme manually:

bash
# Create the themes directory if it doesn't exist
mkdir -p ~/.themes

# Download and extract a theme
cd ~/Downloads
wget https://example.com/mytheme.tar.gz
tar -xf mytheme.tar.gz -C ~/.themes/

Icon Themes​

Icon themes can significantly change the look and feel of your desktop environment.

Installing Icon Themes​

Icon themes are typically installed to:

  • System-wide location: /usr/share/icons/
  • User-specific location: ~/.icons/

To install an icon theme:

bash
# Create the icons directory if it doesn't exist
mkdir -p ~/.icons

# Download and extract an icon theme
cd ~/Downloads
wget https://example.com/icon-theme.tar.gz
tar -xf icon-theme.tar.gz -C ~/.icons/

  • Papirus: Modern icon theme with a clean design

    bash
    sudo apt install papirus-icon-theme

  • Tela: Flat, colorful icon theme

    bash
    # Clone the repository
    git clone https://github.com/vinceliuice/Tela-icon-theme.git
    cd Tela-icon-theme
    # Install the theme
    ./install.sh

Font Customization​

Changing fonts can improve readability and aesthetics.

Installing Fonts​

bash
sudo apt update
sudo apt install fonts-noto fonts-roboto fonts-firacode

Setting Fonts in GNOME​

  1. Open GNOME Tweaks
  2. Go to the "Fonts" section
  3. Change the font settings according to your preference

GNOME Shell Extensions​

GNOME Shell extensions add functionality and customization options to the GNOME desktop environment.

Installing GNOME Extensions Support​

bash
sudo apt update
sudo apt install gnome-shell-extensions gnome-shell-extension-manager

Alternatively, install the browser extension and GNOME Shell integration:

bash
sudo apt install chrome-gnome-shell

Then visit extensions.gnome.org in your browser.

Useful GNOME Extensions​

  1. Dash to Dock: Transforms the dash into a dock

    • Install via Extensions Manager or:
    bash
    sudo apt install gnome-shell-extension-dash-to-dock

  2. User Themes: Allows changing the GNOME Shell theme

    • Install via Extensions Manager or:
    bash
    sudo apt install gnome-shell-extension-user-theme

  3. GSConnect: Integration with Android devices

    • Install via Extensions Manager or:
    bash
    sudo apt install gnome-shell-extension-gsconnect

Desktop Configuration​

Customizing GNOME with dconf-editor​

The dconf-editor lets you modify system settings not accessible through the normal Settings interface.

bash
sudo apt install dconf-editor

Launch it from the applications menu and navigate through the settings hierarchy.

Example: To change the number of workspaces:

  1. Navigate to /org/gnome/desktop/wm/preferences/
  2. Modify the num-workspaces key

Using gsettings for Command-Line Configuration​

Change settings directly from the terminal:

bash
# Set the desktop background
gsettings set org.gnome.desktop.background picture-uri 'file:///path/to/image.jpg'

# Enable dark theme
gsettings set org.gnome.desktop.interface gtk-theme 'Adwaita-dark'

Customizing KDE Plasma​

KDE Plasma offers extensive customization options through its System Settings application.

Global Themes​

  1. Open System Settings
  2. Navigate to "Appearance" → "Global Themes"
  3. Browse and apply available themes or download new ones

Plasma Widgets​

Widgets can be added to the desktop or panels:

  1. Right-click on desktop or panel
  2. Select "Add Widgets"
  3. Drag and drop widgets to your preferred location

Custom Shortcuts​

  1. Open System Settings
  2. Navigate to "Shortcuts"
  3. Add new or modify existing shortcuts

Terminal Customization​

Enhancing Bash with .bashrc​

Edit your ~/.bashrc file to customize your Bash experience:

bash
# Add these to your ~/.bashrc
# Custom prompt
PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

# Useful aliases
alias ll='ls -alF'
alias la='ls -A'
alias l='ls -CF'
alias update='sudo apt update && sudo apt upgrade'

After editing, reload with:

bash
source ~/.bashrc

Installing and Configuring Zsh​

Zsh offers more features than Bash:

bash
# Install Zsh
sudo apt install zsh

# Install Oh My Zsh for easy configuration
sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Edit ~/.zshrc to customize Zsh:

bash
# Set theme
ZSH_THEME="agnoster"

# Enable plugins
plugins=(git docker composer npm)

Desktop Effects and Animations​

Compiz for Advanced Desktop Effects​

For Ubuntu-based Debian systems:

bash
sudo apt install compizconfig-settings-manager

Launch CompizConfig Settings Manager to customize effects.

KDE Desktop Effects​

  1. Open System Settings
  2. Navigate to "Workspace Behavior" → "Desktop Effects"
  3. Enable or disable effects according to your preference

Creating a Custom Application Launcher​

Create a .desktop file to add a custom launcher:

bash
# Create the application directory if it doesn't exist
mkdir -p ~/.local/share/applications

# Create a desktop file
cat > ~/.local/share/applications/myapp.desktop << EOF
[Desktop Entry]
Name=My Application
Exec=/path/to/application
Icon=/path/to/icon.png
Type=Application
Categories=Utility;
EOF

Workflow Automation with Custom Scripts​

Create a script to toggle between light and dark themes:

bash
#!/bin/bash
# Save as ~/.local/bin/toggle-theme.sh

CURRENT_THEME=$(gsettings get org.gnome.desktop.interface gtk-theme)

if [[ $CURRENT_THEME == "'Adwaita'" ]]; then
    gsettings set org.gnome.desktop.interface gtk-theme 'Adwaita-dark'
    echo "Switched to dark theme"
else
    gsettings set org.gnome.desktop.interface gtk-theme 'Adwaita'
    echo "Switched to light theme"
fi

Make it executable and create a keyboard shortcut:

bash
chmod +x ~/.local/bin/toggle-theme.sh

Practical Examples​

Create a Productivity-Focused Desktop​

Let's set up a distraction-free, productivity-focused desktop:

bash
# Install needed packages
sudo apt install gnome-tweaks dconf-editor gnome-shell-extension-manager

# Set a solid color background
gsettings set org.gnome.desktop.background picture-uri ''
gsettings set org.gnome.desktop.background primary-color '#2c3e50'

# Disable notifications temporarily while working
gsettings set org.gnome.desktop.notifications show-banners false

# Auto-hide the dock
gsettings set org.gnome.shell.extensions.dash-to-dock autohide true

Create a Custom Application Theme Switcher​

Let's create a script that switches between light and dark themes based on time of day:

bash
#!/bin/bash
# Save as ~/.local/bin/auto-theme.sh

HOUR=$(date +%H)

# If it's between 8am and 6pm, use light theme
if [ $HOUR -ge 8 ] && [ $HOUR -lt 18 ]; then
    gsettings set org.gnome.desktop.interface gtk-theme 'Adwaita'
    gsettings set org.gnome.desktop.interface color-scheme 'default'
else
    gsettings set org.gnome.desktop.interface gtk-theme 'Adwaita-dark'
    gsettings set org.gnome.desktop.interface color-scheme 'prefer-dark'
fi

Add to crontab to run hourly:

bash
chmod +x ~/.local/bin/auto-theme.sh
crontab -e
# Add the following line:
# 0 * * * * ~/.local/bin/auto-theme.sh

Troubleshooting​

Fixing Theme Issues​

If your theme isn't applying correctly:

bash
# Restart the GNOME Shell (on X11 only)
Alt+F2, then enter 'r' and press Enter

# Or log out and back in for Wayland sessions

Resetting to Default Settings​

If customization causes issues, reset to defaults:

bash
# For GNOME
dconf reset -f /org/gnome/

# For KDE
rm -rf ~/.config/plasma-org.kde.plasma.desktop-appletsrc
rm -rf ~/.config/plasmarc
