A Comprehensive Guide to Resetting Ubuntu to Default Settings Without Losing Data

Introduction

Learn how to reset Ubuntu to default settings without losing your data. This guide covers basic and advanced methods to reset your Ubuntu system while keeping personal files intact.

Over time, your Ubuntu system can become cluttered with unnecessary software, tweaks, and misconfigurations, leading to performance issues or unexpected errors. A common solution is to reset Ubuntu to its default settings to regain stability and improve performance, but the fear of losing personal files can be intimidating.

Thankfully, you don’t need to worry about your documents or pictures getting deleted! This guide will walk you through how to reset Ubuntu while ensuring your personal data remains safe. Whether you're a beginner or an advanced user, we’ll cover different methods to reset Ubuntu, from basic graphical interfaces to advanced terminal commands.

Let’s dive into the details!

What Does Resetting Ubuntu Mean?

Resetting Ubuntu refers to reverting all system settings, configurations, and applications to their original state, much like a fresh installation. However, this process does not erase your personal files located in your /home directory. It will:

• Restore system settings to their default values.
• Uninstall non-default applications that you’ve installed.
• Reset desktop environment configurations (such as themes and extensions).
• Keep personal files and data stored in your /home directory intact.

This approach is different from a complete reinstallation, which could involve formatting your system and potentially losing personal data.

Why Should You Reset Ubuntu?

You may consider resetting Ubuntu for several reasons, including:

• System Slowdowns: Over time, your system may accumulate unnecessary software and misconfigurations that can lead to slow performance.
• Software Conflicts: Resetting can resolve issues caused by conflicting or poorly-configured applications.
• Error Resolution: A system reset can fix broken configurations or settings that cause Ubuntu to malfunction.
• Fresh Start: If your system feels cluttered or too heavily modified, resetting offers a clean slate without reinstalling the operating system from scratch.

Backup Your Data First!

Before you start the reset process, it's critical to back up your personal data. Although the reset process typically does not delete personal files, creating a backup ensures that your data is safe in case something goes wrong.

How to Backup Using Deja Dup:

1. Open the Backup tool from your application menu.
2. Select folders and files you want to back up (typically your /home directory).
3. Choose an external drive, cloud storage, or network location for the backup.
4. Click Backup Now and wait for the process to complete.

Alternatively, you can manually backup by copying important files (such as documents, pictures, and downloads) to an external drive or cloud storage.

Methods to Reset Ubuntu Without Losing Data

There are multiple ways to reset Ubuntu to default settings while keeping your data. Below, we cover both simple and advanced approaches.

Method 1: Reset GNOME Settings Using dconf (Beginner-Friendly)

If you're using GNOME (the default desktop environment for Ubuntu), resetting GNOME to its default settings can resolve most desktop-related issues.

1. Open a terminal.
2. Run the following command:

dconf reset -f /

This command resets all GNOME settings, including themes, desktop icons, and extensions. It does not affect your personal files.

Method 2: Reset Desktop Environment Settings (Intermediate)

If you want a more comprehensive reset of your desktop environment (either GNOME or KDE), you can manually reset desktop configurations to default settings.

Reset GNOME:

1. Open the terminal and enter the command:

dconf reset -f /org/gnome/

1. Restart GNOME or log out and back in to apply the changes.

Reset KDE (for Kubuntu Users):

1. Open the terminal and remove all KDE configurations:

rm -rf ~/.kde ~/.kde4 ~/.config/plasma* ~/.local/share/plasma*

Reboot your system:

reboot

This will reset your desktop environment while preserving personal data.

Method 3: Using dpkg-reconfigure to Reset Installed Packages (Advanced)

For more control over resetting system packages and configurations, you can use the dpkg-reconfigure command to restore default settings for installed applications without losing your personal data.

1. Open a terminal.
2. Enter the following command to reconfigure all packages:

sudo dpkg-reconfigure -phigh -a

This method reconfigures installed packages to their default state.

Method 4: Complete System Reset Using Reinstallation (Expert)

If you're looking for a thorough reset, reinstalling Ubuntu without formatting the /home partition is the best option. This method reinstalls the operating system while ensuring your personal files remain intact.

1. Reboot your system and hold Shift to access the GRUB menu.
2. Select Advanced Options > Recovery Mode.
3. Choose Reinstall Ubuntu and follow the on-screen instructions. Ensure you select the option to preserve the /home directory.

Method 5: Using a Live CD/USB for System Reset (Expert)

Another advanced method is resetting Ubuntu using a Live USB. This method allows you to reinstall Ubuntu without formatting your personal files.

1. Boot from a Live USB with Ubuntu installed.
2. Select Install Ubuntu and choose the option to reinstall Ubuntu without formatting the /home partition.
