I know it’s a duplicate of a duplicate of a duplicate… but I tried solutions that I found (about sudo groupadd rfkill and others) and it didn’t work So I will begin with that $ bluetoothctl Agent registered [bluetooth]# power on No default controller available $ sudo systemctl stop bluetooth; sudo /usr/lib/bluetooth/bluetoothd -n -d bluetoothd[315732]: […]

Bluetooth suddenly stopped working Ubuntu 20.04 – No default controller available

Bluetooth worked fine and one fine day (nothing changed), all of a sudden, it won’t turn on from the top right dropdown. The label goes from off to on, but it doesn’t change in Bluetooth Settings. I checked a lot of previous posts, but none of them fixed it. I powered off and went to […]

AC600 wireless NIC will not turn on

I have a brand new Blueshadow AC600 wireless NIC amazon That came with a drivers disk that claimed Linux as an option. The driver installation succeeded but lsusb and ifconfig -a fail to show the device. I found numerous other people that used the rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959 Drivers, but following the dkms installation (error free), I still […]

Bluetooth mouse/keyboard good on 18.04, fails on 20.04

I have a USB Bluetooth adapter that I use for mouse and keyboard. It works fine in 18.04, but does not generate any input on 20.04. The two machines are side by side, making it easy to compare. The device is "seen" (for some level of meaning of "seen") in both machines, it just doesn’t […]

Having used Linux only on servers for the last two decades, my knowledge isn’t up-to-date anymore. I want to use my Magic Mouse (1st gen.) on a brand-new Fedora 32 setup. Pairing with “Settings > Bluetooth” was easy and the mouse basically works. To adjust things like scroll speed, several tutorials say to pass options […]
