It seems the bluetooth subsystem shows some bugs after the upgrade to 13.10. It was working quite happily at 13.04.
The bluetooth mouse I have, simply won't connect after the computer goes into any sort of sleep and has to be re-added each and every time. Sometimes the the entire bluetooth stack has vanished alltogether.
What changed with the bluetooth between these versions, that may cause this?
This is a fresh install of Kubuntu I'm using (bluedevil) no an upgrade, but the same hardware as 13.04 was happy on.
I have reported this as a bug https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1246981
and added the link here as requested.
