In this article, we will discuss several methods to fix slow performance issues on Ubuntu 20.04 with the GNOME desktop. This guide is intended for users who have experienced sluggish performance on their GNOME desktop and are looking for ways to improve it.
Understanding the Problem
The GNOME desktop is known for its simplicity and user-friendly interface. However, some users have reported slow performance on Ubuntu 20.04 with the GNOME desktop. This could be due to various reasons such as high-resolution screens, outdated system or drivers, or power-saving modes.
Method 1: Disable Fractional Scaling and Reduce Screen Resolution
One of the common causes of slow GNOME performance is the use of high-resolution screens. If you are using a high-DPI screen, you might experience sluggish performance due to the high demand on system resources.
To fix this, you can disable Fractional scaling and reduce the screen resolution. To do this, navigate to Settings > Displays. Here, turn off the Fractional Scaling option and reduce the screen resolution to a lower setting.
Method 2: Increase Text Size Using
Another method to improve GNOME performance is to increase the text size. This can be done using the
gsettings command. Open the Terminal and type the following command:
gsettings set org.gnome.desktop.interface text-scaling-factor 1.25
This command sets the text scaling factor to 1.25. The
org.gnome.desktop.interface text-scaling-factor is a configuration key in GNOME that controls the text size. By increasing the text size, you can reduce the demand on system resources, thus improving performance.
Method 3: Update and Upgrade System, Install Latest NVIDIA Driver
Sometimes, slow GNOME performance can be caused by an outdated system or drivers. To fix this, you can update and upgrade your system and install the latest NVIDIA driver.
To update and upgrade your system, open the Terminal and type the following commands:
sudo apt update sudo apt upgrade
sudo apt update command updates the list of available packages and their versions, but it does not install or upgrade any packages. The
sudo apt upgrade command installs newer versions of the packages you have.
After updating and upgrading your system, you can install the latest NVIDIA driver by typing the following command:
sudo apt install nvidia-driver-460
This command installs the NVIDIA driver version 460. Make sure to replace
460 with the latest version available.
Method 4: Disable WiFi Powersave Mode
If you are experiencing slow performance and WiFi disconnection issues, it might be due to the WiFi powersave mode. To disable this mode, open the Terminal and type the following command:
sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
This command changes the WiFi powersave mode from
3 (enabled) to
2 (disabled) in the
Method 5: Reinstall Default NVIDIA Driver
If all else fails, you can try reinstalling the default NVIDIA driver. To do this, open the Terminal and type the following command:
sudo apt install --reinstall xserver-xorg-video-nouveau
This command reinstalls the
xserver-xorg-video-nouveau package, which is the default NVIDIA driver.
In this article, we discussed several methods to fix slow GNOME performance on Ubuntu 20.04. These methods include disabling Fractional scaling and reducing screen resolution, increasing text size using the
gsettings command, updating and upgrading the system and installing the latest NVIDIA driver, disabling WiFi powersave mode, and reinstalling the default NVIDIA driver.
Remember, these solutions may not work for everyone. If you are still experiencing slow performance after trying these methods, it is recommended to seek further assistance.
