Hello,

I have three different keyboards:

- A standard dell keyboard
- A Kinesis Advantage 2
- A Vortex Pok3r

I have two dell machines a desktop which is an OptiPlex (don't recall the model) and a laptop a Dell XPS 9560. The first is running fedora 29 and the latter Ubuntu 18.11, and I have the following issue.

When I use the standard Dell keyboard or the Kinesis with ubuntu under Gnome I have to press SUPER+s to get the activity overview, whilst with the Vortex SUPER is enough as normally. I don't have the issue on the OptiPlex with fedora.
Any ideas why this is and how to fix it?

I put it in the hardware section, although I do not know if it is hardware or Ubuntu that causes the problem.

Also I have tested on a Lenovo Thinkpad with OpenSUSE Tumbelweed with Gnome3, also no issue here.

./looop

The first thing to do is to check what each keyboard is doing. Run the command xev in a terminal and see what you get. For example, pressing the right Super key I get (among other things)
keycode 108 (keysym 0xffec, Super_R)
If your keyboards are not all giving the same result, that's an obvious problem.

Then there's the default setting in the various desktops. Pressing Super alone for the activities overview (whatever that may be — I'd rather eat slugs than use Gnome) is odd, as you should be able to use the Super key in your own shortcuts, but it sounds a Gnomish sort of thing. If the Super key hasn't been hijacked in that way, then the default keyboard configuration may have it tied to Meta or something. You can check that with the keyboard configuration tool.

Thank you for taking the time to help.
