I have been using a Logitech Bluetooth keyboard for a while now with my Ubuntu 20.04. Everything worked well without any issues until one day the operating system refused to turn on the Bluetooth. I could toggle Bluetooth On button from the Settings, but it did nothing.  After spending some time Google Searching why my Bluetooth started not working all of a sudden, and after trying a variety of commands to troubleshoot the problem, I finally found a working fix for this issue.

The odd one out in the lineup is DSC-RX100M5A. During the early days of RX100 series, Sony used to equip the camera with Fast F1.8 lens and a smaller focal length - typically 24-70mm focal length.
