What is a Desktop Environment?
It’s the graphical interface you see after booting: top bar, dock, windows, icons, settings. Ubuntu uses GNOME by default, but you can choose others:
| Environment | Style | Best for |
|---|---|---|
| GNOME | Modern, minimalist | General users, beginners |
| KDE Plasma | Elegant, highly customizable | Power users, aesthetic control |
| XFCE | Lightweight, essential | Older PCs, performance |
| MATE | Classic, familiar | Former Windows XP/Vista users |
Comparison: Windows has a fixed interface (Desktop + File Explorer + Start Menu), while Ubuntu lets you switch and reshape everything.
Basic Customizations (GNOME)
Change wallpaper and lock screen
- Go to Settings → Appearance
- Choose built-in images or upload your own
- Dynamic wallpapers available via extensions
Install GNOME Tweaks
Essential tool to modify themes, fonts, window behavior:
bash
sudo apt install gnome-tweaks
Modify themes and icons
- Download from gnome-look.org
- Place files in
~/.themesand~/.icons - Activate via GNOME Tweaks
Examples:
- Dark theme: Adwaita-dark
- Modern icons: Papirus, Tela
Fonts and scaling
- GNOME Tweaks → “Fonts”
- Improve readability or switch to Ubuntu Mono for terminal
GNOME Extensions
Extensions add features and behavior. To use them:
- Install browser plugin from extensions.gnome.org
- Install shell support:
bash
sudo apt install gnome-shell-extensions
Recommended extensions:
- Dash to Panel – transforms dock into a Windows-style taskbar
- Clipboard Indicator – clipboard history
- Caffeine – prevents screen sleep
- User Themes – enables custom themes
Workspaces and Multitasking
Ubuntu supports virtual workspaces: separate zones to organize windows.
- Switch with
Ctrl + Alt + Arrow - View all with
Super + S(Super = Windows key) - Assign apps to specific workspaces with Auto Move Windows
Comparison: Windows 10/11 has “Virtual Desktops,” but they’re less integrated with app behavior.
Switching Desktop Environments
Try KDE Plasma:
bash
sudo apt install kde-plasma-desktop
Choose it at login screen after reboot.
Other options:
bash
sudo apt install xfce4
sudo apt install ubuntu-mate-desktop
Note: Each environment affects performance and compatibility. GNOME is best supported for beginners.
