Fix Bluetooth Not Found on Ubuntu Desktop

Introduction

There has been a few times that I found that my Bluetooth mouse Logitech MX Master 3 was not working on my Ubuntu 24.04 desktop but it still worked on my other computers such as MacBook Pro. It turns out that the mouse was completely fine and it was because the Bluetooth device could not be found in the operating system at all. Basically, any Bluetooth devices could not be used on the desktop.

In this blog post, I would like to quickly document how I fixed the Bluetooth not found issue on my Ubuntu desktop.

Fix Bluetooth Not Found

The first thing I tried was to run system updates and then reboot the desktop. However, it did not work.

Then I tried to power off the desktop and power on the desktop again by pressing the power button, but that did not work either.

Finally, I tried to power off the desktop, turn off and on the power supply unit (PSU), and then power on the desktop. This time it worked, and the Bluetooth device was found in the operating system again.

Conclusions

This issue has happened to me at least three times. The solution mentioned above has always worked for me.
