Although bluetooth technology is present in many modern devices and equipment, the truth is that users do not use it as frequently as many would like. And although many operating systems like Ubuntu recognize it very well, The truth is that it is usually heavy to have the icon running down battery or energy and not using it.
So in this little guide we tell you how to disable bluetooth in Ubuntu so that the system does not use it and does not use so much energy. This little trick works for all Ubuntu computers, whether they are laptops or desktops as well as for the official flavors.
How to remove bluetooth
Just open a terminal in root mode and type the following:
gedit /etc/rc.local
This will open the famous text editor with a system configuration file. At the end of this file we will see a text that says «exit 0», before this text we will have to put the following:
rfkill block bluetooth
Once it is written, the text should look like the following image:
If so, we save the document and close it, once this is done, every time we restart the system, the bluetooth will not be charged with the consequent energy savings. If, on the other hand, we find that we want to re-enable it, we just have to go to the same file and delete the text that we have added, we save it and voila, the bluetooth reloads. And if we want to activate it and use it temporarily, in system configuration We will have the option to use it temporarily, but once the computer is restarted it will return to its original state, that is, deactivated.
Personally, I am not a big fan of bluetooth on the desktop computer, so I usually disable it unless I want to listen to music that I use bluetooth headphones for that. In any case, bluetooth tends to be annoying to me like many other users, but there are no excuses to deactivate it, don't you think?
