I have a Drevo Calibur 71 USB/Bluetooth keyboard that was working fine until recently.
The problem I am having is that the Super key is not functioning as it should. Actually it does nothing. It works fine on the laptop's keyboard.
I checked a couple of similar questions that involved either a keyboard key that disables the Super key (I don't think this keyboard has one) or using the Tweak Tool. None worked so far.
What might be the problem especially that this thing is recently. They key used to work just fine a few months ago.
PS: I am on Ubuntu Gnome 16.04.5
