Enabling Hibernate on Ubuntu 22.04 LTS: Overcoming the Immediate Wake-Up Issue

Enabling hibernation on Ubuntu 22.04 LTS can be a lifesaver for users who experience unreliable resume processes, especially on machines with dedicated graphics cards like the nVidia RTX 3500 Ada. However, some users may encounter an issue where the machine shuts down but awakens immediately afterward. In this article, we will explore the possible causes and solutions to this problem.

When you enable hibernation on your Ubuntu machine, it saves the current state of the system to the swap partition and then shuts down. However, in some cases, the machine may wake up immediately after shutting down, which can be frustrating and may lead to data loss. This issue can be caused by various factors, including:

  • Insufficient swap space: If the swap partition is too small, the system may not be able to save the current state properly, leading to an immediate wake-up.
  • Graphics card issues: Dedicated graphics cards like the nVidia RTX 3500 Ada can cause problems with hibernation, especially if the drivers are not properly configured.
  • System configuration: Incorrect system configuration, such as the hibernation mode or the swap partition settings, can also cause the machine to wake up immediately.

To troubleshoot the issue, you can try the following steps:

Step 1: Check the Swap Space

First, you need to check if the swap space is sufficient to save the current state of the system. You can do this by running the following command:

sudo swapon -s

This will display the current swap space settings. If the swap space is too small, you can increase it by adding more swap partitions or by allocating more space to the existing swap partition.

Step 2: Check the Graphics Card Drivers

Next, you need to check if the graphics card drivers are properly configured. You can do this by running the following command:

sudo lspci -vnn | grep -i nvidia

This will display the current graphics card settings. If the drivers are not properly configured, you may need to update them or reinstall them.

Step 3: Check the System Configuration

Finally, you need to check the system configuration to ensure that it is set up correctly for hibernation. You can do this by running the following command:

sudo systemctl status hibernate

This will display the current hibernation settings. If the settings are not correct, you may need to modify them to enable hibernation.

After troubleshooting the issue, you can try the following solutions to enable hibernate on your Ubuntu machine:

Solution 1: Increase the Swap Space

If the swap space is too small, you can increase it by adding more swap partitions or by allocating more space to the existing swap partition. You can do this by running the following command:

sudo swapon -s

This will display the current swap space settings. You can then add more swap partitions or allocate more space to the existing swap partition.

Solution 2: Update the Graphics Card Drivers

If the graphics card drivers are not properly configured, you may need to update them or reinstall them. You can do this by running the following command:

sudo apt update
sudo apt install nvidia-driver

This will update the graphics card drivers and reinstall them.

Solution 3: Modify the System Configuration

Finally, you need to modify the system configuration to enable hibernation. You can do this by running the following command:

sudo systemctl edit hibernate

This will open the hibernation configuration file in a text editor. You can then modify the settings to enable hibernation.

Enabling hibernation on Ubuntu 22.04 LTS can be a lifesaver for users who experience unreliable resume processes. However, some users may encounter an issue where the machine shuts down but awakens immediately afterward. In this article, we explored the possible causes and solutions to this problem. By following the troubleshooting steps and solutions outlined in this article, you can enable hibernation on your Ubuntu machine and enjoy a more reliable resume process.

  • Use a larger swap partition: If you have a large amount of RAM, you can use a larger swap partition to ensure that the system can save the current state properly.
  • Update the graphics card drivers regularly: Regularly updating the graphics card drivers can help prevent issues with hibernation.
  • Check the system configuration regularly: Regularly checking the system configuration can help ensure that it is set up correctly for hibernation.

By following these tips and the solutions outlined in this article, you can enable hibernation on your Ubuntu machine and enjoy a more reliable resume process.
