Turn Your Ubuntu Desktop from Ugly Duckling to Swanky in 30 Minutes

Preparation

Install GNOME Tweaks and GNOME Shell extensions.

sudo apt update
sudo apt install gnome-tweaks gnome-shell-extensions

Optional: install the browser extension manager from https://extensions.gnome.org/.

Step 1 – Install core GNOME extensions

Dash to Dock : macOS‑style dock. Install via sudo apt install gnome-shell-extension-dashtodock or from https://extensions.gnome.org/extension/307/dash-to-dock/.

User Themes : enables loading shell themes from ~/.themes. Install from https://extensions.gnome.org/extension/19/user-themes/.

Blur My Shell : adds blur to top bar, dash and overview. Install from https://extensions.gnome.org/extension/3193/blur-my-shell/.

Dash to Panel (optional): Windows‑style taskbar. Install from https://extensions.gnome.org/extension/1160/dash-to-panel/.

Clipboard Indicator : clipboard history. Install from https://extensions.gnome.org/extension/779/clipboard-indicator/.

Caffeine : prevents automatic lock‑screen. Install from https://extensions.gnome.org/extension/517/caffeine/.

OpenWeather : weather display in top bar. Install from https://extensions.gnome.org/extension/750/openweather/.

Step 2 – Install themes

mkdir -p ~/.themes ~/.icons

Dark themes

Nordic : minimalist dark theme. Download from https://github.com/EliverLara/Nordic/releases, unzip into ~/.themes/, then select “Nordic” in GNOME Tweaks → Appearance → Applications.

Flat‑Remix‑GTK : flat dark theme. Download from https://github.com/daniruiz/flat-remix-gtk/releases, unzip into ~/.themes/, then select “Flat‑Remix‑GTK‑Red‑Dark”.

Light theme

WhiteSur‑gtk‑theme : macOS Big Sur style. Clone from https://github.com/vinceliuice/WhiteSur-gtk-theme, run ./install.sh -c Light, then select “WhiteSur‑Light”.

Step 3 – Install icon themes

Tela Icon Theme : modern colorful icons. Clone from https://github.com/vinceliuice/Tela-icon-theme, run ./install.sh, then select a “Tela‑red” variant in GNOME Tweaks → Appearance → Icons.

Papirus : flat icons. Install with

sudo add-apt-repository ppa:papirus/papirus && sudo apt update && sudo apt install papirus-icon-theme

, then choose “Papirus‑Dark”.

Flat‑Remix : gradient icons. Download from https://github.com/daniruiz/flat-remix-gtk/releases, unzip into ~/.icons/, then select “Flat‑Remix‑Blue‑Dark”.

Step 4 – Set wallpaper

Static sources: Unsplash (https://unsplash.com/wallpapers), Wallhaven (https://wallhaven.cc/), Reddit r/wallpapers (https://www.reddit.com/r/wallpapers/).

Dynamic wallpapers (advanced): build Komorebi from https://github.com/cheesecakeufo/komorebi.git with:

sudo apt install git valac libgtk-3-dev libsoup2.4-dev libjson-glib-dev libwebkit2gtk-4.0-dev libgee-0.8-dev
git clone https://github.com/cheesecakeufo/komorebi.git
cd komorebi
make
sudo make install
komorebi

Or install HydraPaper for multi‑monitor wallpaper management:

sudo apt install hydrapaper

Step 5 – Top‑bar customization

Hide date or seconds via GNOME Tweaks → Top Bar.

Install Vitals (CPU, memory, network, optional temperature) from https://extensions.gnome.org/extension/1460/vitals/ and enable the desired indicators.

Make the panel transparent or blurred with Blur My Shell or by editing ~/.themes/Nordic/gnome-shell/gnome-shell.css:

/* ~/.themes/Nordic/gnome-shell/gnome-shell.css */
#panel {
    background-color: rgba(46, 52, 64, 0.5);
}

Quick one‑click script

#!/bin/bash
sudo apt update
sudo apt install -y gnome-tweaks gnome-shell-extensions git

mkdir -p ~/.themes ~/.icons

# Papirus icons
sudo add-apt-repository -y ppa:papirus/papirus
sudo apt update
sudo apt install -y papirus-icon-theme

# Nordic theme
cd /tmp
wget https://github.com/EliverLara/Nordic/releases/download/v2.0.0/Nordic-standard.tar.xz
tar -xf Nordic-standard.tar.xz
mv Nordic-standard ~/.themes/Nordic

# Tela icons
git clone https://github.com/vinceliuice/Tela-icon-theme.git
cd Tela-icon-theme
./install.sh

echo "Beautification complete – open GNOME Tweaks to select theme and icons."

Save as ubuntu-beautify.sh, make executable with chmod +x ubuntu-beautify.sh, then run ./ubuntu-beautify.sh.

Common issues

Extensions not taking effect – restart GNOME Shell (Alt+F2, type r) or log out/in.

Theme not visible in Tweaks – verify that ~/.themes/Nordic/gtk-3.0/ etc. exist and that User Themes extension is enabled.

Icon theme partially applied – some applications (e.g., Firefox, LibreOffice) use their own icons.

System slowdown – Blur My Shell may affect performance; reduce blur strength or disable. Dynamic wallpapers consume more resources.

Advanced tweaks

Install Conky for on‑desktop system monitoring: sudo apt install conky-all && conky-manager.

Deeply edit GNOME Shell CSS (e.g., panel height, colors, notification style) in ~/.themes/Nordic/gnome-shell/gnome-shell.css and restart the shell.
