I know the xps series doesn't play well with ubuntu by reading about a hundred tutorials on different way to fix the bluetoooth connectivity problem. For some reason Nothing has worked for me. I tried to add the hcd file to no avail. I tried just about everything and im stumped. This is a pretty serious issue because im on my 5th set of speakers, this laptop is notorious for blowing speakers, i was hoping to just connect bluetooth speakers to avoid this problem. If anyone can help be diagnose this issue i would be greatly appreciate it and Please dont delete this thread it hasn't been answered before. Nothing has worked on my device for some reason.
