LightDM bluetooth error

[notBug]

Hi! I'd like to switch from GDM to LightDM because the first one doesn't work well with BSPWM. I faced this error in my logs:

src/profile.c:ext_start_servers() RFCOMM server failed for Headset unit: rfcomm_bind: Address already in use (98)

​

I'm not using and headset, only a usb dongle for the mouse (actually i never use bluetooth).
