I installed a fresh Ubuntu 17.10 and tested my Bluetooth settings. I have two Logitech X100 Bluetooth speakers. hciconfig -a returns this when I turned on my bluetooth:

Now the first issue was, that when I connect to the speakers, it disconnects after a few seconds and it disappears in the audio settings. More strange, the Bluetooth speakers and Ubuntu are still paired (the LED is still on (not blinking) and Ubuntu shows me its connected). In Ubuntu I cannot disconnect the speakers anymore, because I got a timeout for this action (seen in the sys-logs).
So I tried installing Blueman, and it didn't help, so I uninstalled it again. Now I cannot find the first Bluetooth box anymore (it never appears in the scan-list) and I cannot connect to the second speakers (at least, Ubuntu bluetooth can find them). More strange, Ubuntu thinks it connects and pairs with the 2nd speakers, but the speaker itself shows me, nothing happened.
And again, disconnect won't work because Ubuntu receives a timeout.
Any ideas?
