I will try it tommorrow. Just one further question, as I have never done this before....
Can I upgrade the Kernel by using the MX Package Installer? Or is it better to use Synaptic Package Manager as decribed in the manual on pages 184-185?
I have a new bluetooth adapter (usb) that seems to be recognized (I can activate it with blueman), but I cannont connect the earphones JLab Go Air Pop to it. Unfortunatly, this device is not found by blueman. I don't have other BT devices ...
