I had a bad time with ubuntu 18 lts and Bluetooth. Neither bluez nor the other one (forget which) would recognise the controller in my mobo. Tried the man pages. Searched high and low. Asked for help on the forums - got nothing. Decided to never again try using Linux for my workstation. I’m perfectly happy to use it to run my scripts, daemons and containers on a dedicated box, but there’s just no upside for my games and work machine.
