Introduction

Ubuntu 22.04 LTS is a popular Linux distribution known for its user-friendly interface and robust features. However, some users may experience a blur effect on their lock screen, which can be distracting and affect the overall user experience. In this article, we will guide you on how to remove the blur effect on the lock screen in Ubuntu 22.04 Desktop, using a custom background image, without accessing the machine directly via SSH.

Understanding the Blur Effect

The blur effect on the lock screen is caused by the GNOME Shell's built-in feature, which applies a blur effect to the background image to create a sense of depth and dimension. However, this effect can be removed by editing a configuration file.

Prerequisites

Before you begin, make sure you have the following:

  • Ubuntu 22.04 LTS installed on your machine
  • A custom background image set on your lock screen
  • SSH access to your machine (optional)

Method 1: Editing the Configuration File

To remove the blur effect on the lock screen, you need to edit the gnome-shell.css file, which is responsible for the GNOME Shell's styling. You can do this by following these steps:

Step 1: Connect to your machine via SSH

If you have SSH access to your machine, you can connect to it using a tool like ssh or a graphical client like sshfs. This will allow you to edit the configuration file remotely.

ssh your_username@your_machine_ip

Step 2: Navigate to the GNOME Shell configuration directory

Once you are connected to your machine, navigate to the GNOME Shell configuration directory using the following command:

cd ~/.config/gnome-shell

Step 3: Edit the gnome-shell.css file

Use a text editor like nano or vim to edit the gnome-shell.css file:

nano gnome-shell.css

Step 4: Remove the blur effect

In the gnome-shell.css file, search for the following line:

background-blur: 0.5;

Replace this line with the following code to remove the blur effect:

background-blur: 0;

Step 5: Save and exit

Save the changes you made to the gnome-shell.css file and exit the text editor.

Step 6: Restart the GNOME Shell

Restart the GNOME Shell to apply the changes:

gnome-shell --replace

Method 2: Using the dconf Editor

Alternatively, you can use the dconf editor to remove the blur effect on the lock screen. Here's how:

Step 1: Install the dconf Editor

If you don't have the dconf editor installed, you can install it using the following command:

sudo apt-get install dconf-editor

Step 2: Launch the dconf Editor

Launch the dconf editor using the following command:

dconf-editor

Step 3: Navigate to the GNOME Shell settings

In the dconf editor, navigate to the following path:

org/gnome/shell/extensions/blur-background

Step 4: Disable the blur effect

In the blur-background settings, toggle the enabled switch to false to disable the blur effect.

Step 5: Save and exit

Save the changes you made to the dconf editor and exit the application.
