"No bluetooth found"

[Marco A Ramirez]

I'm running on Ubuntu 20.04. My system has a dual-boot installation and Bluetooth works fine on Windows. however whenever I try to turn it on on Ubuntu, the settings GUI displays the message "No Bluetooth found, plug in dongle to use Bluetooth".

My device uses an Intel Wireless-AC 9462 card that drives both WiFi and Bluetooth.

If I check the service status it says that Bluetooth is running but it won't show on my settings menu...
