Traditional integer-based scaling often falls short, either making items too small or excessively large. Fractional scaling settings, however, provide a more granular control, enabling you to adjust scaling in non-integer increments such as 1.25x or 1.75x.

On the GNOME desktop, the introduction of fractional scaling has been a game-changer. GNOME 45 has redesigned its display settings to offer a more intuitive experience, making it simpler for you to find and adjust these settings. This allows for a more precise adjustment of text and UI element sizes, ensuring they're neither blurry nor disproportionate.

Using fractional scaling settings on GNOME, you can achieve a perfect balance, enhancing your visual experience without compromising clarity. This is particularly advantageous for users moving from older legacy HiDPI settings, as it provides better control and compatibility. By leveraging fractional scaling, your GNOME desktop environment adapts seamlessly to your high-resolution display needs.

Enabling Fractional Scaling in GNOME

To enable ideal scaling in GNOME, you'll need to use the terminal to adjust the scaling factors. Open your terminal and enter the following command:


gsettings set org.gnome.mutter experimental-features '['scale-monitor-framebuffer']'


This command enables the experimental feature required for fractional scaling. Once enabled, restart your system to apply the changes effectively.

After the restart, navigate to GNOME Settings. Go to the 'Displays' section where you can now see new scaling options. You can choose from scaling factors like 125%, 150%, and 175% to better fit your display needs.

Installing GNOME Tweaks is highly recommended for fine-tuning. Use it to adjust font scaling and experiment with different scaling factors for an optimal display. Run the following command to install GNOME Tweaks:


sudo apt install gnome-tweaks


Keep in mind that some applications may not scale correctly with fractional scaling enabled. Test your most used applications to identify any issues and make necessary adjustments. The process may require some experimentation to achieve the best visual experience, but the added flexibility in display settings is well worth it.

Optimizing Display Settings

Once you've enabled fractional scaling in GNOME, optimizing your display settings guarantees the best visual clarity and user experience.

Start by adjusting the scaling factor to balance text and UI elements. By selecting options like 125%, 150%, or 175%, you can find the perfect fit for your high-resolution screen. Fine-tuning these settings will prevent blurriness and secure a balanced desktop display.

To further refine your display, use GNOME Tweaks. This tool allows you to customize the font scaling, which can greatly enhance readability. Navigate to the 'Fonts' section in GNOME Tweaks and experiment with different scaling values until text appears sharp and clear.

Compatibility With Applications

When you enable fractional scaling in GNOME, some applications may not adapt well, causing UI elements to appear incorrectly sized. This can impact performance and resource usage, making it important to test various programs.

To mitigate these issues, consider exploring scaling workarounds and tweaks to guarantee better compatibility and usability.

Application UI Adaptation

Many applications struggle with fractional scaling, leading to UI elements that appear either too small or excessively large. This challenge stems from the fact that not all applications are designed to handle scaling adjustments dynamically.

When you enable fractional scaling, older or less frequently updated applications may not adapt well, resulting in visual inconsistencies that can greatly disrupt your user experience.

Application UI adaptation to fractional scaling is crucial. Developers need to guarantee their applications support scaling properly to maintain ideal usability. Without these updates, you might encounter issues with text and graphic sizing that make the application difficult to use.

For instance, text might appear blurry or excessively large, while graphical elements can become misaligned.

To address these issues, actively test different scaling factors on your applications and provide feedback to developers. This helps identify specific scaling problems and encourages developers to implement necessary adjustments. By doing so, you contribute to a smoother, more consistent user experience across various applications.

Performance and Resource Use

Enabling fractional scaling can strain system resources, affecting performance and compatibility with legacy applications. Fractional scaling increases power usage because it requires additional computational steps to divide pixels, leading to a higher demand on the GPU and CPU. This added strain can lower your system's speed and responsiveness, especially on hardware with limited resources.

Compatibility issues are another concern. Many legacy applications weren't designed with fractional scaling in mind, resulting in UI elements that may not render correctly. These applications might appear blurry or improperly sized, impacting usability. The nature of fractional scaling necessitates rendering at non-integer scales (like 125%), which can introduce visual imperfections and reduce display sharpness on fixed pixel screens.

Unlike Windows, which directly renders at 125% without downscaling from 200%, Linux Gnome's fractional scaling often needs to handle more complex scaling operations. This difference can exacerbate performance issues and increase power usage. Consequently, users may experience a noticeable drop in system efficiency and battery life.

Scaling Issue Workarounds

Addressing scaling issues in Linux Gnome often requires adjusting individual application settings to guarantee better compatibility and peak display performance. Since some applications don't naturally scale well with fractional scaling, manual adjustments become important to make sure a consistent user experience.

Here are some steps you can take to tackle these challenges:

  1. Adjust Font Sizes: Many applications allow you to set custom font sizes within their settings. Tweaking these can help you achieve better readability and interface clarity, especially on high DPI displays.
  2. Experiment with Scaling Factors: Some applications offer internal scaling options. Experimenting with these can help you find a balance that aligns with your overall system settings, reducing inconsistencies.
  3. Understand Application Behavior: Different applications behave uniquely under fractional scaling. Familiarize yourself with how each app responds to scaling adjustments to tailor your settings effectively.

Managing Multiple Displays

When managing multiple displays, you'll need to configure display settings to guarantee peak performance. Use Wayland to set different scaling factors for each monitor, or xrandr's `scale` option for non-HiDPI monitors.

Adjust each monitor's resolution and sharpness to avoid blur and maintain clear visuals.

Configuring Display Settings

Configuring display settings in GNOME lets you manage multiple monitors with different scaling factors to suit various resolutions and DPI settings. With fractional scaling, you can precisely set the best display settings for each monitor, guaranteeing sharp and clear visuals.

Here's how you can get started:

  1. Open Settings: Navigate to the 'Settings' application in GNOME.
  2. Access Displays: Go to the 'Displays' section to view connected monitors.
  3. Set Scaling Manually: Select each monitor and apply the appropriate scaling factor to match its resolution and DPI.

When dealing with high resolution displays, it's important to manually adjust the scaling factor for each monitor. This ensures that text and images don't appear too small or too large, maintaining a coherent desktop environment.

GNOME's flexibility allows you to customize each monitor's settings individually, which is especially useful for multi-monitor setups with varying resolutions.

Optimizing Screen Resolution

To achieve the best screen resolution across multiple displays, you'll need to adjust each monitor's resolution and scaling settings individually. In Gnome Shell, this involves configuring fractional scaling to guarantee each display looks sharp and clear, particularly when dealing with varied DPI settings.

Begin by using the xrandr command to identify your monitors and their respective names. Once identified, set the resolution and scaling for each display. For example, you might use `xrandr –output HDMI-1 –scale 1.25×1.25 –mode 1920×1080` to scale an external monitor properly. This secures that text and images are sharp without any blur.

When managing multiple monitors, consider how each display's resolution interacts. If you encounter scaling challenges, adjust the settings incrementally to find the best balance.

Mirroring displays can be straightforward with xrandr, using commands like `xrandr –output HDMI-1 –same-as eDP-1`, but extending displays will require more nuanced adjustments to maintain clarity.

Troubleshooting Common Issues

Encountering blurry text or UI elements with GNOME's fractional scaling can often be resolved by fine-tuning the scaling values. If you're using fractional scaling in Ubuntu within the GNOME desktop environment, follow these steps to address common issues:

  1. Adjust Scaling Values: Use the GNOME Tweaks tool to modify the scaling values incrementally. This can help you find the best display settings to eliminate blurriness.
  2. Xwayland Applications: Some applications running under Xwayland may not scale correctly. Adjust the individual scaling factors for these applications or try switching to Wayland-native versions if available.
  3. Monitor Compatibility: Check your monitor settings in GNOME's display settings. Make sure that your monitor is properly recognized and configured. Incompatible monitor settings can lead to performance and scaling issues.

Additionally, if you encounter performance challenges, optimize system resources by closing unnecessary applications and processes. This can enhance the overall performance and responsiveness of fractional scaling.

Future of Fractional Scaling in GNOME

GNOME's future plans for fractional scaling include a redesigned display settings menu to enhance user understanding and usability. The current setup, which involves a percentage slider, may soon be replaced to offer more clarity. Allan Day from the GNOME design team has discussed these changes in a GitLab issue, emphasizing a need for a more intuitive interface.

The redesigned display settings could include fewer options to streamline user choices, a preview feature to immediately show scaling effects, and a legacy compatibility mode switch for X11 applications. This approach aims to simplify fractional scaling management and reduce user confusion. The legacy mode will guarantee older applications remain functional without compromising the overall experience.

These enhancements are targeted for inclusion in GNOME 45 or a subsequent point release by the end of the year. This timeline indicates a commitment to providing a more polished and user-friendly display configuration experience. By focusing on these improvements, GNOME aims to address existing pain points and deliver a more seamless fractional scaling setup, making it easier for users to achieve ideal display settings without hassle.
