Description epp 2024-06-07 01:21:29 UTC 
Beginning with an upgrade to Plasma 6, Bluetooth comes up disabled the vast 
majority of the time after login. Unknown as to the cause. The Bluetooth dongle has a blue light on it that will come on during the login process, then goes out after one second. When the desktop appears, Bluetooth is disabled.

There is an unexpected NULL in the journal when checking the status of bluetooth.service.

In attempting to remedy this issue, it was said that the problem is likely in bluez, which would be upstream.
