In this article, we will be discussing how to fix GNOME lag on Ubuntu 18.04, specifically when using Nvidia drivers. If you’ve been experiencing sluggish performance on your Ubuntu system, this guide will provide you with several potential solutions to enhance your user experience.
Understanding the Problem
GNOME is a popular desktop environment used by many Linux distributions, including Ubuntu. However, users may experience performance issues, such as lag or stuttering, especially when using Nvidia graphics drivers. This can be due to a variety of factors, including the specific driver version, system configuration, or GNOME extensions in use.
Solution 1: Disable GNOME Extensions
One potential cause of lag in GNOME is the use of extensions. While these can provide additional functionality, they can also consume system resources and cause performance issues.
To disable GNOME extensions, you will need to use the GNOME Tweak Tool. If you don’t have it installed, you can install it using the following command:
sudo apt install gnome-tweak-tool
Once installed, open the GNOME Tweak Tool and navigate to the Extensions tab. Here, you can disable all extensions to see if it improves the system performance.
Solution 2: Disable Animations
Another potential cause of lag is the use of animations within the GNOME desktop environment. While these can enhance the visual appeal of the desktop, they can also contribute to system lag.
To disable animations, you can use the GNOME Tweak Tool. Navigate to the Appearance tab and toggle the Animations switch to off.
Solution 3: Use a Different Nvidia Driver
The specific Nvidia driver you’re using can also impact the performance of GNOME. If you’re using the Nvidia 390 driver and experiencing lag, you may want to try a different driver.
To do this, you can use the Ubuntu Driver Manager, which allows you to easily switch between different drivers. Open the Driver Manager, select a different driver (such as the 960 or 340.106 driver), and click Apply Changes.
Solution 4: Switch to a Different Desktop Environment
If you’re still experiencing lag after trying the above solutions, you may want to consider switching to a different desktop environment. Other environments, such as Mate or Budgie, are known for their smooth performance and may provide a better user experience.
To install a different desktop environment, you can use the following command:
sudo apt install ubuntu-mate-desktop
Replace “ubuntu-mate-desktop” with the package name of the desktop environment you want to install.
Solution 5: Check for Other Potential Causes
If none of the above solutions work, there may be other factors causing the lag. Check your system’s CPU usage to ensure it’s not abnormally high. You can do this using the System Monitor tool in Ubuntu.
Also, consider removing any unnecessary startup applications or services. You can manage startup applications using the Startup Applications tool in Ubuntu.
In this article, we’ve discussed several potential solutions to fix GNOME lag on Ubuntu 18.04 with Nvidia drivers. It’s important to remember that the performance of GNOME can vary depending on your specific system configuration, so you may need to experiment with different solutions to find what works best for you.
To install the GNOME Tweak Tool, open a terminal and run the command
sudo apt install gnome-tweak-tool.
After installing the GNOME Tweak Tool, open it and go to the "Extensions" tab. From there, you can disable individual extensions or toggle the switch to disable all extensions.
Open the GNOME Tweak Tool and navigate to the "Appearance" tab. Look for the "Animations" option and toggle the switch to disable animations.
Open the Ubuntu Driver Manager and select a different driver from the available options. Click "Apply Changes" to switch to the selected driver.
To install a different desktop environment, open a terminal and run the command
sudo apt install [desktop-environment-package-name]. Replace
[desktop-environment-package-name] with the package name of the desktop environment you want to install.
Open the System Monitor tool in Ubuntu. In the "Resources" tab, you will find information about your system’s CPU usage.
Use the Startup Applications tool in Ubuntu to manage startup applications. You can find it by searching for "Startup Applications" in the applications menu.
