Ubuntu 16.04 patched to date.
Below is the sequence of re-enabling the bluetooth mouse after suspend. Note
that
either of two different things being blocked, tpacpi_bluetooth_sw, and hci0,
will
keep the mouse from working.
After a resume from suspend, the title bar bluetooth icon is greyed out.
$ rfkill list
0: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: yes
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
>From title bar bluetooth icon, started bluetooth settings, and in the
settings, turned the bluetooth switch off, then on. Title bar icon disappeared,
then reappeared greyed out.
$ rfkill list
0: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
26: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
After turning on the bluetooth switch from the title bar bluetooth icon
the icon became white, and connected with the bluetooth mouse.
$ rfkill list
0: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
26: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
