I think I get what you mean: true, when the ‘master’ visibility (the normal or leftmost columns of lightbulbs) is turned off, you cannot toggle the Layout’s or Detail’s visibility. So, turn on the ‘master’ lightbulb, then you can toggle. This is indeed unsatisfactory, since the visibility of things in a Layout should ideally be decoupled from the model space. It’s possible to get the job done, but you need to be careful and do your extra clicks.
I revommend using Layer States for your Layouts/Details.
There’s a lengthy debate about the whole Layout topic here:
