I'm new to Linux and am having terrible difficulty getting my bluetooth devices to pair/connect. I'm using a bluetooth dongle on my Dell Inspiron 910 running Lubuntu 12.04.2 LTS. I've tried blueman bluetooth manager and bluetooth-applet (which I think came preinstalled with Ubuntu) but both crash my system whenever I attempt to pair/connect devices.
I don't fully understand it at this point but I've read that there is a problem with the bluez package/stack. There doesn't seem to be much support availbable the subject. At this point I'm completely unsure as to what package I should be using for bluetooth functionality or what packages I need to have installed/uninstalled. If you could point me in the right direction I'd be very greatful. I recently bought a Logitech K810 keyboard which I can only stare at for the moment.
