Meanwhile the keyboard is working too. I can't really tell what made the
change. I suspect that fully switching off the tablet for some hours did
reset something in the device?

>From my position this issue can be closed as solved.

Title:
  Bluetooth not working after upgrade to Ubuntu 15.10

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have a Acer w700 with Bluetooth keyboard and a Logitech Mouse M555b. In 15.04 all was working fine, both paired and working.
  Now after the Upgrade:
  No Bluetooth icon visible (but I could get it back using system settings, Bluetooth and set the check box. 

  If I search on my cellphone to find the tablet it does not show up
  anything (as if it is not running). But my Bluetooth settings on the
  tablet say "on" and "visible".
