How to connect Microsoft Arc Touch Bluetooth Mouse in Ubuntu 20.04

us flag

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!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
