How to Fix Lagging Issues on Ubuntu 22.04: A Simple Guide

If you’re experiencing lagging or performance issues on Ubuntu 22.04, this guide will walk you through a quick fix by tweaking a configuration file. Follow these steps, and you should notice an improvement in performance.

Why Does This Work?

Sometimes, Ubuntu systems may face lagging or slow performance due to power management settings, especially on certain hardware. By adjusting the GRUB bootloader settings to force ACPI (Advanced Configuration and Power Interface), you can resolve these issues.

Steps to Fix Ubuntu 22.04 Lagging

1. Open GRUB Configuration with Gedit

First, we need to edit the GRUB configuration file. To do this, open the terminal (Ctrl + Alt + T) and type the following command:

sudo gedit /etc/default/grub

This command opens the GRUB configuration file in Gedit with superuser permissions. You’ll need to enter your password when prompted.

2. Modify the GRUB Configuration

Once the GRUB file is open, locate the line that contains quiet splash. It’s usually on line 10.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Now, add acpi=force right after quiet splash, so the line looks like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

This adjustment forces the ACPI (power management) settings, which can resolve many lagging issues on certain systems.

3. Save the File

After making the change, save the file by clicking Save in the Gedit toolbar or pressing Ctrl + S.

4. Quit Gedit

Once saved, close Gedit by clicking Quit or pressing Ctrl + Q.

5. Update GRUB and Restart

Finally, you’ll need to update GRUB to apply the changes and restart your system. Back in the terminal, run this command:

sudo update-grub

After the update is complete, restart your computer:

sudo reboot

Conclusion

And that’s it! After the reboot, your system should feel snappier, and the lagging issue should be resolved. By adding acpi=force to your GRUB configuration, you’re enabling power management optimizations that can drastically improve performance on some hardware.
