Who is XFCE for?
XFCE is built for users who demand maximum performance without the baggage of modern desktop bloat. It is the go-to environment for those who want their Arch Linux system to feel instantaneous, whether they are reviving legacy hardware or squeezing every bit of power out of a high-end workstation. If you prefer a traditional desktop metaphor that is rock-solid, predictable, and stays out of your way so you can focus on real work, XFCE is exactly what you need.
Prerequisites
Before starting the installation, ensure you have a functional Arch Linux base system. This guide is tailored for users starting from a fresh command-line interface (TTY), but it works perfectly if you are adding XFCE as a secondary desktop environment. Arch Linux allows you to install multiple environments, giving you the flexibility to switch to a lightweight XFCE session whenever you need maximum performance.
If your base system isn't ready yet, choose the path that fits your expertise:
- Master the Process: Follow my Comprehensive Arch Linux Manual Installation to learn exactly how your system is built from the ground up.
- Skip the Complexity: Use my pre-configured scripts to Automate Your Arch Linux Setup, perfect for deploying a clean base environment in just a few minutes.
Once your base system is ready and you have sudo privileges, you are all set to deploy the XFCE desktop.
Hardware Recommendation:
- Processor: Any 64-bit processor (even older dual-core CPUs)
- RAM: 1GB minimum (2GB or more recommended)
- Storage: 10GB of free disk space
- GPU: Any integrated or dedicated graphics card
- Network: Stable internet connection
Step 1: Prep Arch Linux for XFCE
Before installing the desktop environment, it is essential to ensure your system is fully synchronized and has a reliable connection to the Arch repositories. In this step, we will perform a full system update to prevent package conflicts and configure the nameservers to guarantee stable network resolution during the installation process.
1.1: Check for a Full System Upgrade
Running a full system update is a critical first step on Arch Linux to maintain system integrity. Since Arch is a rolling-release distribution, installing new software on an outdated base can lead to "partial upgrades," which often cause package conflicts or broken dependencies. By synchronizing the system with the latest repositories, we ensure that the XFCE packages and their libraries are compatible with the current kernel and system tools.
- Run the following command:
sudo pacman -Syu1.2: Configure Nameservers
Configuring nameservers in the /etc/resolv.conf file is a common practice to ensure fast and reliable domain name resolution. By manually adding high-performance DNS addresses, such as Google or Cloudflare, you provide your system with a reliable backup for translating web addresses into IP addresses. While Arch Linux often handles network settings automatically, verifying this configuration helps prevent potential "temporary failure in name resolution" errors during the package download process.
- To add nameservers, simply run:
sudo echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf
# OR
sudo echo "nameserver 1.1.1.1" | sudo tee /etc/resolv.conf
Step 2: Install XFCE4 Package Group & LightDM
In this step, we will deploy the core XFCE4 desktop environment along with the LightDM display manager to handle your graphical login. This combination ensures a lightweight foundation while providing a professional interface to access your Arch Linux session.
2.1: Install XFCE4 Package Group
- Run the following command:
sudo pacman -S xfce4 xfce4-goodies
- After initiating the installation, pacman will prompt you to select specific packages from the xfce4 group. To ensure a complete desktop experience, simply press Enter to select "all" core components by default.
- Next, you will be prompted to choose features from the xfce4-goodies group. Again, for a full-featured environment with all extra plugins and tools, press Enter to install the entire selection.
- After selecting, pacman will calculate all dependencies and prompt you to confirm the installation.
- Simply press Enter to continue with the process.
2.2: Install LightDM Greeter
A display manager requires a visual interface to interact with, known as a Greeter. We will install the lightdm-gtk-greeter, which provides a clean and lightweight login screen, allowing you to securely enter your credentials and select your XFCE session upon system startup.
- To install lightdm and its greeter, run:
sudo pacman -S lightdm lightdm-gtk-greeter
Step 3: Configure LightDM & Install Additional Tools
With the desktop environment in place, we will now finalize the setup by installing essential applications and enabling the display manager. In this step, we will install Falkon as a lightweight web browser and VLC for media playback, while activating the LightDM service to ensure the system boots directly into the XFCE graphical login screen.
3.1: Install Essential Tools
To complement a lightweight setup, we will install Falkon, a browser that perfectly matches XFCE's philosophy by using QtWebEngine for minimal RAM consumption and low system resource usage. We will also include VLC, the most versatile media player, ensuring your system is ready for web browsing and high-quality media playback right out of the box.
- Run the following command:
sudo pacman -S falkon vlc
- After searching for falkon & vlc, pacman will prompt for Choosing Audio Backend for VLC. For a modern and robust setup, type 2 to choose pipewire-jack and press Enter.
- Next, pacman will prompt for Choosing ttf-font. Press Enter to proceed with the default gnu-free-fonts.
- After selecting, pacman will calculate dependencies and prompt to Confirm packages to install?.
- Simply press Enter to continue.
3.2: Enable LightDM Service
Activating the LightDM service is crucial as it automates the transition from the command-line interface to the graphical welcome screen. By enabling this unit, your Arch Linux system will consistently launch the XFCE login manager upon every system boot.
- We will enable and start the lightdm service simultaneously without needing an immediate reboot.
- Run:
sudo systemctl enable lightdm --now
Step 4: Log into XFCE
After enabling LightDM, your screen may go black for a few seconds as the graphical server initializes. Shortly after, you will be greeted by the LightDM login screen, prompting you to enter your credentials:
Simply type your password and press Enter to launch your session:
And just like that, you are in!
Fin!

Frequently Asked Questions: XFCE on Arch Linux
What is XFCE and why should I use it on Arch Linux?
XFCE is a lightweight desktop environment that focuses on speed and low resource usage while maintaining a traditional desktop metaphor. On Arch Linux, it provides a minimal yet fully functional graphical interface that runs fast even on older hardware. It is ideal for users who want a stable, configurable, and efficient environment without the bloat of modern desktop effects. XFCE uses minimal RAM and CPU, making it perfect for reviving older machines or building a lean daily driver.
How do I install XFCE on Arch Linux?
Installation is simple using pacman. First ensure your system is updated with sudo pacman -Syu. Then install the core XFCE group and goodies:
sudo pacman -S xfce4 xfce4-goodies
During installation, pacman will ask you to select components from the groups. Press Enter to install all of them for a complete desktop experience. This installs the panel, window manager, desktop manager, and essential plugins.
What display manager should I use with XFCE on Arch?
LightDM is the recommended display manager for XFCE because it is lightweight and integrates well. Install it along with the GTK greeter:
sudo pacman -S lightdm lightdm-gtk-greeter
After installation, enable the service to start at boot:
sudo systemctl enable lightdm --now
The --now flag starts the service immediately so you can log in without rebooting.
Why do I need xfce4-goodies? What does it include?
xfce4-goodies is a package group containing extra plugins and standalone applications that enhance the XFCE experience. It includes additional panel plugins, a system monitor, power manager, terminal enhancements, a dictionary, and many small utilities that make the desktop more functional. While not strictly required, installing it gives you a fully featured environment out of the box.
What web browser and media player do you recommend for a lightweight XFCE setup?
For a lightweight browser, Falkon is an excellent choice. It uses QtWebEngine and consumes minimal RAM while providing modern web capabilities. For media playback, VLC is the most versatile player. Install them with:
sudo pacman -S falkon vlc
During VLC installation, you will be prompted to select an audio backend. Choose pipewire-jack (option 2) for modern audio handling.
How do I enable LightDM to start automatically on boot?
After installing LightDM, enable and start the service with:
sudo systemctl enable lightdm --now
This command configures LightDM to start at every boot and also launches it immediately so you can see the login screen without restarting. If you ever need to disable it, use sudo systemctl disable lightdm.
I'm on a minimal Arch install. Do I need to configure network or audio separately for XFCE?
Network management is usually handled by NetworkManager or systemd-networkd. XFCE does not include a network manager by default. You can install NetworkManager and its applet:
sudo pacman -S networkmanager network-manager-applet
Then enable it: sudo systemctl enable NetworkManager --now. For audio, install pipewire and pipewire-pulse if not already present. XFCE will automatically use the system audio.
Can I install XFCE alongside another desktop environment like KDE or GNOME?
Yes, Arch Linux allows multiple desktop environments to coexist. After installing XFCE, you can select your desired session from the display manager (LightDM) login screen. Each DE keeps its own configuration files, so they won't interfere. However, having multiple DEs may increase disk usage and occasionally cause theme conflicts, but it is perfectly safe and common.
How do I switch from my current DE to XFCE if I already have another one installed?
Install XFCE and LightDM as described. Then, if you are using a different display manager (like SDDM for KDE), you can either keep it and select XFCE from the session menu at login, or switch to LightDM by enabling it and disabling the other DM. For example:
sudo systemctl disable sddm sudo systemctl enable lightdm --now
Reboot or restart the DM service to see the change.
Why is LightDM not showing the XFCE session option?
This usually means the desktop entry for XFCE is missing or LightDM cannot find it. Ensure that xfce4-session is installed (it is part of the xfce4 group). Check the available sessions with:
ls /usr/share/xsessions/
You should see xfce.desktop. If it's missing, reinstall xfce4. Also, restart LightDM with sudo systemctl restart lightdm.
How much RAM does a minimal XFCE installation on Arch use?
A freshly booted XFCE session on Arch typically consumes around 400 to 600 MB of RAM, depending on which services and panel plugins are running. This makes it one of the lightest full-featured desktop environments available. With additional optimizations (disabling compositing, removing unused services), you can reduce it even further.
Can I customize XFCE to look modern while staying lightweight?
Absolutely. XFCE is highly customizable. You can install themes, icons, and window manager decorations from the AUR or community repos. Popular choices include arc-gtk-theme, papirus-icon-theme, and xfce4-whiskermenu-plugin. While adding visual effects may slightly increase resource usage, XFCE remains efficient compared to heavier DEs. Use the built in Appearance and Window Manager settings to tweak the look.
Why does my screen go black after enabling LightDM?
This is normal. When LightDM starts, it switches from the virtual console to the graphical server, which may cause a brief black screen for a few seconds. If the black screen persists, it could indicate a driver issue (e.g., missing GPU drivers or wrong display manager configuration). Check that you have the appropriate drivers installed (e.g., mesa for AMD/Intel or nvidia for NVIDIA) and that LightDM is properly configured. You can also check logs with journalctl -u lightdm.
How do I update XFCE and its components after installation?
Since Arch is a rolling release, simply running a full system update will keep all XFCE packages up to date:
sudo pacman -Syu
This will upgrade the kernel, XFCE, and all other software. It is recommended to reboot after a kernel update to ensure all modules load correctly.
