We're supposed to show a "No Wacom tablets / Plug one in" message in place of the UI when a tablet is not connected, or gets disconnected.

Jakub, could you please mock that up?

My gut feeling is to not show the panel at all when we don't detect any (just like we don't show anything to configure for a touchpad when you don't have one). On the other hand we do show 'no adapter present' for Bluetooth. Jon?

I'd also prefer not to show settings panel that aren't applicable. I'm not sure it is worth showing a bluetooth panel when there is no adapter present either.

maybe grey out the icon in the panel? If I bought a tablet a year after using GNOME, I wouldn't think of going to the system settings when I plug one in. simply because I've never seen it there before.

otoh, if the icon is there but greyed out I'd know immediately where to go. Same is true for bluetooth of course.

Peter, good point.

On the other hand, System Settings is starting to fill up. I think we're up to 20 icons now. The more icons, the harder it is to find what you're actually looking for.

It is, because hardware is shit. Some killswitches (whether software or hardware) will simply remove the device from the USB bus. And how to you re-enable the Bluetooth adapter if you can't go in the Bluetooth panel to re-enable it?

Bastien, are we still waiting for a mockup for this ?

Yes, and Peter to implement it.

Peter is travelling - first xdc, then westford. I wouldn't expect anything from him this week.

:( should really just hide it.

Thank you for the screenshot. As we discussed on IRC, I would really like to avoid showing an icon in System Settings for hardware that only a fraction of people will have. Adding things comes at a cost. 

I am not opposed to allow people to get to this panel in the illustrated (hw undetected) state. The panel could come up through system settings search or gnome-shell search (perhaps with a semi-opaque icon as Peter suggested). The use case here being 'i accidentally flipped the bluetooth radio switch and my table stopped working. where is it?'

But I would really like to avoid growing the system settings icon view.

Note that:
gnome-control-center wacom
would certainly give you that same page.

For 3.4, we would hide the icon in the overview, but making sure it shows up in the search results. It also needs to be hotpluggable. None of the code that's available right now can do that.

Will file a separate bug for the visibility.

There's already bug 650699, even though it's not Wacom specific.

One thing that makes this panel so much worse than just the generic case is that not only is the hardware exceptionally rare but the panel uses a brand name.
