I am using Fedora with vanilla GNOME + a few extensions since Fedora 25 and since Fedora 32 the Super key doesn’t work anymore.
Since it was an upgrade from Fedora 31, I just freshly reinstalled Fedora 32, but I still have the issue. I tried with another keyboard and I got the same issue as well (keyboard brands: Cooler Master and WASD).
That said, my machine in the living room is also on Feodra 32, but it’s using a Logitech wireless keyboard (with a proprietary USB dongle), and there the Super key works!
Do you have any idea why it was working before and now it doesn’t? Is it an upstream bug and a fix is on the way?
