How To Fix Black Screen After Suspend in Ubuntu 22.04 LTS?

If you’re an Ubuntu 22.04 LTS user and you’ve encountered a black screen after suspending your computer, it can be a frustrating experience. This issue is often related to the graphics card driver, and it can be resolved by following a few steps. In this article, we’ll provide several solutions to tackle this problem.

Solution for NVIDIA Graphics Cards (Driver 510)

For users with NVIDIA graphics cards using driver 510, the issue may be caused by NVIDIA systemd services. Here’s how to disable them:

1. Open your terminal.
2. Run the following commands:

   sudo systemctl stop nvidia-suspend.service
   sudo systemctl stop nvidia-hibernate.service
   sudo systemctl stop nvidia-resume.service
   
   sudo systemctl disable nvidia-suspend.service
   sudo systemctl disable nvidia-hibernate.service
   sudo systemctl disable nvidia-resume.service

   These commands stop and disable the NVIDIA systemd services related to suspend, hibernate, and resume.
3. Now, remove the NVIDIA systemd script by executing the command:

   sudo rm /lib/systemd/system-sleep/nvidia

   This command removes the script that NVIDIA uses during system sleep.
4. Finally, reboot your system. The suspend and resume functionality should now work properly with driver 510 for both X11 and Wayland.

Downgrading NVIDIA Driver from 510 to 470

Another solution that has worked for some users is downgrading the NVIDIA driver from version 510 to 470. Here’s how to do it:

1. Open the “Additional Drivers” application. This application allows you to manage proprietary drivers for your hardware.
2. Select the NVIDIA driver version 470 and apply the changes. This will downgrade your NVIDIA driver to a version that may be more stable.
3. Reboot your system. The black screen issue should now be resolved.

Workaround for NVIDIA Driver 515 and CUDA 11.7

If you’re using NVIDIA driver 515 and CUDA 11.7, you may encounter the black screen problem after suspension. Here’s a workaround:

1. If you encounter a black screen after suspension, press Ctrl+Alt+F1 to switch to a virtual console. This is a terminal-like interface that operates outside of your graphical user interface (GUI).
2. Now, revert to the GUI session by pressing Ctrl+Alt+FX, where X is the virtual console number you switched from. This should bring you back to your GUI session.

Solution for AMD Graphics Cards

For users with AMD graphics cards, the solution may involve installing the amdgpu-install package. Here’s how to do it:

1. Open your terminal.
2. Run the following command:

   amdgpu-install --usecase=graphics

   This command installs the amdgpu-install package, which is designed to improve the performance of AMD graphics cards.
3. Make sure to check the secure boot support before installing the AMD graphic card components. This ensures that your system’s security features will not interfere with the installation.

Changing Graphics Card Driver

If you’re using an NVIDIA graphics card, changing the driver to “NVIDIA driver 515 tested” may resolve the issue. Here’s how to do it:

1. Open the “Additional Drivers” application.
2. Select “NVIDIA driver 515 tested” and apply the changes.
3. Reboot your system.

Upgrading NVIDIA Driver to Version 525

Finally, if you’re using a GeForce GTX 1060 graphics card on Ubuntu 22.04, upgrading the NVIDIA driver to version 525 may resolve the problem. Here’s how to do it:

1. Open the “Software & Updates” application. This application allows you to manage your system’s software and updates.
2. Select the NVIDIA driver version 525 and apply the changes. This will upgrade your NVIDIA driver to the latest version.
3. Reboot your system.

We hope that these solutions help you resolve the black screen issue after suspension in Ubuntu 22.04 LTS. Remember to back up your important data before making any changes to your system. If you encounter any issues, don’t hesitate to seek help from the Ubuntu community.
