Hide default Bluetooth
by admin ·
Bluetooth is a wireless technology. Bluetooth devices can connect and exchange data.
Very useful for example to send files to your mobile phone or connect a wireless keyboard and mouse. A few days ago I have a new laptop, Samsung RF710 (publish a review later). Most laptops come with Bluetooth. When you install Ubuntu, I’ve noticed that the Bluetooth connection is active by default.
This means that switching on the computer, and during the time that we work on it, Bluetooth is on. That means more battery consumption. By working with laptops the battery life is critical. If we do not consistently use Bluetooth, it makes sense to activate only when we use it.
You can manually turn on the icon which appears in the upper right of the screen. But if we are going to use a little, not very logical to have to turn off the connection every time we turn on the computer. The most practical is to reconfigure our Bluetooth connection, so that default is not active.
When you want to use, simply click on the Bluetooth icon and select “Switch.” In this way we ensure that connects only when indicated, saving resources in our laptop battery.
To disable the default Bluetooth connection, I followed these steps.
I open the terminal (Applications> Accessories> Terminal) and write:
sudo gedit /etc/rc.local
This line indicates that I will open the file / etc / rc.local with the gedit text editor. Is a configuration file, so I write sudo to start to run the command admin user (root). Then I asked for the password.
This opens the text editor with the file we will modify. Now, before the entry exit 0 must add this line:
rfkill block bluetooth
Save the changes and restart the Bluetooth system should be turned off by default. Continue to see the Bluetooth icon, which will serve to turn the connection when needed.
These steps may serve for other distributions besides Ubuntu. I have not had a chance to prove it. If someone can confirm, please do leave a comment.
