apt commands to purge the desktop environment safely.
Understanding the Access Barrier
XFCE is a lightweight desktop environment that relies on a suite of interconnected packages. Removing it cleanly requires executing commands like sudo apt remove xfce4 and sudo apt autoremove. These commands demand superuser privileges. If you do not have a default root account (which is standard in modern Ubuntu-based distributions) and cannot open a terminal, you are locked out of the package manager. You must first regain access to a command-line interface with root capabilities.
Using Recovery Mode for Root Access
The most reliable method to bypass the lack of a standard root password is using the GRUB recovery menu. This feature is built into the Linux kernel boot process and does not require prior authentication. Follow these steps to gain access:
- Restart your computer and hold down the Shift key (or repeatedly tap Esc) during boot to access the GRUB menu.
- Select the entry labeled Advanced options for Ubuntu (or your specific distribution).
- Choose the line ending with (recovery mode).
- In the recovery menu, select root Drop to root shell prompt.
This action mounts your filesystem in read-write mode and gives you a root shell. You can now proceed with the removal commands. Note that if you previously edited keyboard shortcuts in Xubuntu, ensure you do not rely on graphical tools while in this mode, as the display server is not active.
Purging XFCE Packages
Once you have the root shell, you must ensure the package database is up to date before removing anything. Run the following commands sequentially:
apt update
apt purge xfce4 xfce4-goodies
apt autoremove --purge
The purge flag removes configuration files as well as the binaries, ensuring a cleaner removal than remove. The autoremove step cleans up orphaned dependencies that were installed specifically for XFCE but are no longer needed by other core system components. After execution, type reboot to restart the system.
Alternative: Using an Alternative Admin Account
If you have another user account on the system that belongs to the sudo group, you can log in via the graphical login screen (LightDM or GDM). Once logged in, press Ctrl+Alt+T to open a terminal. Since you already have terminal access here, you can simply run sudo apt purge xfce4. Enter the password for that user when prompted. This method is less invasive than recovery mode and preserves your current session data if you need to save work first.
Post-Removal Considerations
After removing XFCE, your system will likely fall back to a generic fallback session or require you to install a new desktop environment like GNOME or KDE. If you plan to switch to a different DE, you may encounter issues with display managers. For instance, if you previously dealt with panel crashing issues, those are specific to XFCE and will not persist in a new environment. However, you should verify that your display manager is correctly configured for the new DE.
If you intend to keep the system minimal, consider installing a window manager like Openbox instead of a full desktop environment. This reduces resource usage significantly. Be aware that removing XFCE might also remove Thunar file manager settings. If you later reinstall XFCE, your previous Thunar Places list configuration will be lost unless you backed up the ~/.config/thunar directory before removal.
Frequently Asked Questions
Will removing XFCE delete my personal files?
No, removing the desktop environment does not delete user data stored in your home directory. Your documents, images, and downloads remain intact. Only the system packages related to the graphical interface are removed.
Can I fix screenshot errors after switching from XFCE?
Yes, but you must reinstall the appropriate screenshot tool for your new environment. If you switch to GNOME, use gnome-screenshot. If you return to XFCE, ensure xfce4-screenshooter is installed. Refer to our guide on fixing screenshot errors in XFCE if you encounter issues after reinstallation.
What happens to my custom keyboard shortcuts?
All custom shortcuts defined in XFCE are stored in ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml. These files are deleted during a purge. You will need to recreate them manually in your new desktop environment.
Is it safe to use recovery mode for package removal?
Yes, recovery mode provides a standard root shell identical to any other privileged terminal. It is safe for package management. However, avoid modifying critical system files outside of /etc/apt or package directories unless you know exactly what you are doing.
How do I check if XFCE is fully removed?
Run dpkg -l | grep xfce. If no output appears, the packages are gone. If some residual config files remain, they are usually in ~/.cache or ~/.local and can be manually deleted if desired.
