I have Intellij Idea, which has its own shortkeys bound to Ctrl + Alt + F10, and I got some weird screen blackout after pressing these keys on my Ubuntu.
I was only able to switch my screen back after pressing Super + F2.
What does this key combination do? How can I disable it?

These keys switch to virtual consoles, in as far as these are active. In a default installation of Ubuntu, no consoles are set up above Ctrl+Alt+F6, which is why you see nothing more than a blinking cursor after pressing that keyboard combination. Hit Ctrl+Alt+F2 or simply Alt+F2 to return to your graphical desktop. You have virtual consoles available on Ctrl+Alt+F3 up to F6.
