I’ve been using PureOS for a while now and I quite like it, no real reason to switch. About a week ago I tried out Qubes for the second time and while I like the concept I don’t feel the need to use it yet, so I reinstalled PureOS.
Bluetooth worked fine before, but now it doesn’t. The KDE bluetooth icon is grayed out and the settings prompt to “Enable Bluetooth”, but the button does nothing. Clicking on the KDE bluetooth icon says “No Bluetooth Adapters Available”.
I’ve tried tons of solutions online, looking up several different queries to describe my problem, but nothing has worked. I’ve left the machine asleep for a full day and shutdown for a full day, but that did nothing. Even live distros on a USB do not show bluetooth.
Any help is appreciated.
