Please close the bug report.

The problem in this case was the TLP (linrunner) addition. I'm sorry for
that but I had to struggle with bluedevil and KDE, and other (K, X, L)
and Ubuntu bluetooth issues.

Title:
  Bluetooth - rtl8723bt doesn't work anymore - Xubuntu, KDE -  vivid

Status in bluez package in Ubuntu:
  New

Bug description:
  At least in Beta 1 and Beta 2 of Xubuntu, bluetooth worked fine after
  installing the latest bluetooth driver from LWfinger
  (https://github.com/lwfinger/). After the latest kernel release I'm
  not able to get bluetooth to work anymore.

  With Kubuntu (vivid) there was and is no way to get rtl8723au_bt
  running.

  Hardware Lenovo Yoga 11, WiFi = RTL8723 works without any problem but rtl8723au_bt means no external mouse.
  In addition to Xubuntu (vivid) the TLP repository with TLP is installed.
