Public bug reported: Occassionally the mouse gets disconnected and then cannot reconnect by itself, even when it is powercycled.
Workaround: sudo /etc/init.d/bluetooth restart solves the issue and the mouse will reconnect immediately again, no pairing is necessary. Also occasionally when listening music via bluetooth (Sennheiser Momentum 4), the sound is stuttering. The expectation is that bluetooth is stable and works reliable. michael@thinkpad:~$ lsb_release -a No LSB modules are available.
