I am running Linux Mint, with Cinnamon 19. I accidentally pressed Super-O, and the following popup icon appeared:

Pressing Super-O again seems to 'toggle' the setting, now showing this:

I looked through all of the keyboard shortcuts listed in the keyboard preferences, but Super-O wasn't listed.

I want to find out what exactly Super-O does, and what is the default option, so I can put it back how it was?

Screen rotation on/off. Some laptops support it much like tablets and phones.


The configuration is in System Settings -> Keyboard -> Shortcuts -> System -> Hardware -> Orientation Lock. The default option is "Super-O". You can reset it to "unassigned" or assign it with a new key.

    “mumble mumble mumble Orientation Lock” doesn’t answer the question: what does it do? If you mean this to be a supplement to the other answer; don’t do that.  Each answer should answer the question all by itself. (You may refer to other answer(s).) Commented Apr 4, 2020 at 22:54
  • Thanks for the comment. I was answering the "what is the default option, so I can put it back how it was?" part.

    OK; so what is the default option?  I don’t see where you answered that. Commented Apr 5, 2020 at 3:25
  • Thanks. The answer is updated.

  • But you’re answering the wrong question. The question isn’t “What is the default keyboard shortcut for Orientation Lock?”; it is “What is the default state for Orientation Lock: this or this?” Commented Apr 6, 2020 at 2:54
