Pairing a Logitech MX Master Mouse with Ubuntu 16.04 Using Bluetooth

Compared to when I used to download 3.5″ install images to set up Slackware on my machine, Linux has grown by leaps and bounds in terms of usability.  The majority of things seem to “just work” these days.  However, every once in awhile I run into some kind of weird issue.

In this case, I wanted to pair my MX Master Wireless Mouse with my Lenovo laptop running Ubuntu 16.04.  I don’t use the unifying receiver (which, to be honest, I don’t even know if I still have) because I generally just pair with Bluetooth so I have one less dongle to mess with.  That’s even more important in the case of a small laptop that doesn’t have a lot of USB ports to spare.

Adding a bluetooth device is theoretically pretty straightforward.  Go into the bluetooth settings and click ‘Add Device’ while the mouse is in pairing mode.  It actually finds the MX Master just fine, and even claims to complete the pairing process.

However, it still doesn’t recognize the mouse, and the led for the connection is still blinking instead of staying solid.  After a lot of googling, I finally found a solution that worked for me.  Once you have gone through the regular pairing procedure, enter the following commands (as root):

hciconfig hci0 sspmode 1
hciconfig hci0 down
hciconfig hci0 up

Voila, a working mouse!
