How to Set Up Fractional Scaling on CentOS 7

Fractional scaling is a feature that allows you to adjust the size of elements on your screen to make them more readable and easier to interact with. This can be especially useful if you have a high-resolution display or if you have difficulty reading small text or icons. In this article, we will guide you through the process of setting up fractional scaling on CentOS 7.

Step 1: Check Your Display Settings

Before enabling fractional scaling, it's important to make sure that your display supports it. To check your display settings, follow these steps:

1. Click on the "Activities" button in the top-left corner of your screen.
2. Type "Settings" and click on the "Settings" icon.
3. In the "Settings" window, click on "Displays" in the left-hand menu.
4. Look for the "Scale" option. If it is not present, it means that your display does not support fractional scaling.

Step 2: Install GNOME Tweaks

In order to enable fractional scaling, we need to install a tool called GNOME Tweaks. GNOME Tweaks provides additional settings and customization options for the GNOME desktop environment. To install GNOME Tweaks, follow these steps:

1. Open a terminal by clicking on the "Activities" button and typing "Terminal".
2. In the terminal, type the following command and press Enter:

   sudo yum install gnome-tweak-tool

3. Enter your password when prompted and press Enter.
4. Wait for the installation to complete.

Step 3: Enable Fractional Scaling

Once GNOME Tweaks is installed, we can enable fractional scaling. To do this, follow these steps:

1. Open GNOME Tweaks by clicking on the "Activities" button and typing "Tweaks". Click on the "Tweaks" icon to open the application.
2. In GNOME Tweaks, click on "Fonts" in the left-hand menu.
3. Look for the "Scaling Factor" option. By default, it is set to "1".
4. Click on the arrow next to the "Scaling Factor" option to reveal additional options.
5. Select the fractional scaling option that suits your needs. You can choose from options like "1.25", "1.5", or "2".
6. Close GNOME Tweaks. The fractional scaling setting will be applied immediately.

Congratulations! You have successfully set up fractional scaling on CentOS 7. You should now notice that the elements on your screen are larger and easier to read.
