How To Fix “NVIDIA X Server Power Safe Mode Unavailable” Issue

Ubuntu 2

In this article, we will discuss how to resolve the “NVIDIA X Server Power Safe Mode Unavailable” issue. This problem usually arises when the NVIDIA X Server doesn’t allow the user to switch to the “Intel (Power Saving Mode)” on their laptop, even after rebooting the system. Let’s delve into the potential solutions for this problem.

Quick Answer

To fix the "NVIDIA X Server Power Safe Mode Unavailable" issue, you can try manually switching to Intel mode using the terminal, updating your NVIDIA drivers, or reporting a bug to NVIDIA or your Linux distribution maintainers.

Understanding the Issue

The NVIDIA X Server is a crucial component that provides a graphical interface for configuring NVIDIA graphics cards. Sometimes, due to various reasons like driver updates or system changes, the power safe mode, which is designed to save power by switching to the integrated Intel graphics, becomes unavailable. This can lead to higher power consumption and decreased battery life on laptops.

Solution 1: Using Terminal to Switch to Intel Mode

One of the simplest solutions to this problem is to manually switch to Intel mode using the terminal. Here’s how you can do it:

  1. Open your terminal. You can do this by pressing Ctrl + Alt + T or by searching for ‘Terminal’ in your applications.
  2. In the terminal, type the following command: sudo prime-select intel

This command is used to switch between NVIDIA and Intel graphics. The sudo part of the command gives you administrative privileges, while prime-select is a utility that allows you to select the graphics card. The intel parameter tells the utility to switch to Intel graphics.

  1. Press Enter to execute the command.

After executing this command, your system should switch to Intel mode. However, this solution might not always work, as the NVIDIA X Server Settings app may still show the Intel option as greyed out and unavailable.

Solution 2: Updating NVIDIA Drivers

If the first solution doesn’t work, it may be due to outdated NVIDIA drivers. Updating these drivers could potentially fix the issue. Here’s how you can update your NVIDIA drivers:

  1. Open your terminal.
  2. Type the following command: sudo apt-get update

This command updates the list of available packages and their versions, but it does not install or upgrade any packages.

  1. Next, type the following command: sudo apt-get upgrade

This command actually installs newer versions of the packages you have.

  1. Finally, reboot your system to ensure the changes take effect.

Solution 3: Reporting a Bug

If none of the above solutions work, it could be a bug or a limitation imposed by NVIDIA. In such cases, it’s best to report the issue to NVIDIA or the maintainers of your Linux distribution. You can report bugs to NVIDIA through their official website.

Conclusion

The “NVIDIA X Server Power Safe Mode Unavailable” issue can be a frustrating problem, but it’s usually solvable with a bit of troubleshooting. By manually switching to Intel mode, updating your NVIDIA drivers, or reporting a bug, you should be able to resolve the issue and get your system running smoothly again.
