GUI session is on ctrl+alt+f1, I want it on ctrl+alt+f7

Summary: Usually if I wanted to switch from a terminal back to the GUI I’d press ctrl+alt+f7. Now the GUI loads instead on ctrl+alt+f1, and ctrl+alt+f2 to ctrl+alt+f6 are terminals. Ctrl+alt+f7 shows absolutely nothing, just a blinking line. Is there any way to make it load on f7 instead?
Note: I don’t know in what category to put this question.
