I have been curious for some time now if there is any difference between them besides one being located in "Display Configuration" and the other in "Power Management". They seem a bit redundant to me so as if the folks from the Plasma team weren't sure where to put and how to name it, lol. >.<
I think presentation mode inhibits notifications so that if you're presenting something, your presentation won't be interrupted. Can't remember where I read it though
Ahhhh, thanks.
I would never have spotted the difference cuz I'm always on Do not disturb :')
