I am relatively new to Ubuntu and I am having problems to connect my Arc Touch Bluetooth Mouse to my Dell laptop running Ubuntu 20.04.
I read the answers to this question: Microsoft Arc Touch Bluetooth Mouse not working on Ubuntu 16.04, and found that typing in command line:
$ sudo btmgmt le on
... makes the mouse discoverable and makes it possible to pair and connect and to use it properly.
However, if I close and reopen the laptop, the mouse does not connect anymore, I need to retype the command in the terminal again.
Any ideas of how can I make this setting permanent? Thanks!
