Exclamation I'm having trouble using bluetooth in Xubuntu.

What's up, guys. I've recently purchased a USB bluetooth adapter and some peripherals. Under Windows 10, I am able to easily pair and connect these devices. Under Xubuntu, though, that's a different story. I can see the devices, pair them with the computer, and even connect them. However, within a few seconds, the status bars in the bluetooth manager fade away and the connection is lost.

Code:

logs can be found in /var/log, and you need to look for any bluetooth related messages. also you can try the command dmesg
