Understanding High CPU Usage

1. What Causes High CPU Usage?

High CPU usage occurs when the processor works harder than usual to execute tasks. In the context of GNOME Shell, this can happen due to various factors such as resource-intensive applications, malfunctioning extensions, or system misconfigurations.

2. Impact of High CPU on System Performance

High CPU usage can significantly impact system performance, leading to sluggishness, unresponsiveness, and decreased overall productivity. It can also increase power consumption, affecting battery life on laptops and mobile devices.

Why Does GNOME Shell High CPU?

1. Extensions

Including extensions in GNOME Shell can enhance your computer’s functionality, yet poorly coded or outdated ones may strain the CPU unnecessarily. To resolve this problem, simply disable or uninstall the troublesome extensions.

2. Resource-Intensive Activities

If you use resource-intensive applications like video editors or virtual machines, GNOME Shell may experience higher CPU usage.

In such cases, the responsibility for the increased CPU usage lies with the applications running on GNOME Shell.

3. Background Processes

Background tasks such as indexing and thumbnail creation can consume significant CPU resources on your computer.

When you add or modify files, the system may automatically organize them to facilitate easier searching. You can adjust these settings to optimize system performance.

4. Driver Issues

Problems with graphics drivers, particularly those provided by GPU manufacturers like NVIDIA, can impact CPU power consumption.

It’s essential to ensure your computer has the latest and correct hardware drivers installed.

5. Outdated Software

Using an outdated version of GNOME Shell can result in sluggish performance and excessive CPU usage on your computer.

To address this issue, update to the latest version, which can resolve known issues and improve overall speed.

6. Extensions Conflicts

Issues may arise when various GNOME Shell plugins need to collaborate effectively, causing excessive CPU usage.

To identify the culprit, try enabling or disabling each plugin individually to pinpoint the one causing the problem.

How To Fix GNOME Shell CPU High?

1. Check For Gnome Shell Extensions

  • Open your web browser and go to the GNOME Extensions website.
  • Install the GNOME Shell Integration extension for your browser. This helps you control extensions right from your browser.
  • Click on the Integration extension icon in your browser.
  • Check the extensions you’ve installed and see which ones are turned on.
  • Make sure your extensions work well with your GNOME Shell version.
  • Sometimes, extensions might not work correctly with newer GNOME Shell versions, causing performance problems.
  • Keep an eye out for updates to your extensions.
  • Developers often release updates to fix issues and make extensions work better with the latest software, improving performance.

2. Reduce Gnome Shell Animations

Even though the animations in GNOME Shell look nice, they can use much of your computer’s power. You can use GNOME Tweaks to control them:

  • If you still need to add GNOME Tweaks, use your package manager.
  • Open GNOME Tweaks and go to the “Appearance” section.
  • Adjust or turn off the effects according to your preference.

3. Check For Graphics Driver Updates

Ensure your computer has the most up-to-date graphics drivers. Outdated or incorrect drivers often lead to high CPU usage.

To check and install drivers from a specific company, like NVIDIA:

Use the command: sudo pacman -S Nvidia.

4. Evaluate Desktop Background

A complex or high-resolution desktop background can sometimes make your CPU work harder. Consider changing the background to something more straightforward to reduce the strain on your CPU.

5. Check Resource-Hungry Applications

Background applications using lots of CPU can make GNOME Shell slow. Use system tracking tools like “htop” or the system monitor to find processes using too many resources. If you have extra programs running, consider closing or removing them from your computer.

To add “htop”

Use the command: sudo pacman -S htop

6. Review Gnome Shell Settings

To decrease CPU usage, you can adjust GNOME Shell settings. Open the GNOME Tweaks tool and navigate to the “Appearance” tab. Lower the settings for animations and effects, or disable them altogether.

7. Switch From Wayland To Xorg

Sometimes, if you use GNOME on Wayland, it can make your CPU work harder. To switch to Xorg, you can change your display manager configuration. Usually, you’d edit the /etc/gdm/custom.conf file and set WaylandEnable=false.

Use this command: sudo nano /etc/gdm/custom.conf

Make sure Wayland is disabled and the GNOME session is running on Xorg.

8. Evaluate Third-Party Tools

Additional tools can offer assistance but may also strain your CPU. Assess their impact on your system and contemplate using alternatives that are better suited to your computer’s capabilities.

9. Kernel Rollback

If you suspect that a kernel change is causing issues, you can revert to the previous version (5.19.0-45) and verify if the problem persists.

You can select the older kernel version from the GRUB menu during the boot process to perform this action. If the issue disappears with the old kernel, it’s likely caused by the new kernel.

10. Review Unattended Upgrades

As the issue coincided with an automatic kernel update, examine the logs for any changes that occurred without your intervention.

Investigate whether there are any known issues associated with your current kernel version. Updates to the kernel can occasionally introduce problems that lead to increased CPU usage.

Here are a couple of potential reasons:

  1. To eliminate the seconds from the clock, execute the command: `gsettings set org.gnome.desktop.interface clock-show-seconds false`
  2. Look for ‘System Load Indicator’ in the menu for a CPU usage monitor. Stop the process and turn off autostart, or set a longer probing time, like 10 seconds, to make it less resource-intensive.
  3. Be cautious of any applications with real-time monitoring for disk, CPU, or network activities.
