I come from Fedora 22 and 23, because it had support for my BLE mouse (Microsoft Designer Mouse). I decided to switch to the "stable" 16.04 because I like Unity more than gnome. To make my mouse at least pair with my PC, I had to remove 50-bluetooth-hci-auto-poweron.rules from and uncommented autoenable=true from /etc/bluetooth/main.conf (as indicated here https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1510570).

Sometimes when I boot up the computer, the mouse works (although it stops working after a while), and sometimes don't. For example, today I restarted my pc 10 times without success. Yesterday, it worked after 3 reboots. Please help me, this is really getting annoying.

It would be great if there were a way to know what differs from the fedora configuration, because on that system it worked just perfectly.


I solved replacing the gnome bluetooth default indicator with blueman (which is even better and has more options, I really wonder why it is not default)

cd /usr/share/upstart/sessions

sudo mv indicator-bluetooth.conf indicator-bluetooth.conf.old

sudo apt install blueman

Then I restarted and reassociated the mouse. Now it works flawlessly at any time.


I also have a similar problem. I'm using Ubuntu 16.04 and a Microsoft Designer Mouse. The mouse works on bootup but then stops working after a random amount of time. Turning bluetooth off and on again using the icon in the notification bar works for me, but this is really annoying.

  • Unfortunately it stopped working for me, no matter what I do, what did you do to connect the mouse? Did you follow the procedure I linked (deleting that file and enabling autoenable)? – Marc May 26 '16 at 7:28
