Used Ctrl-Alt-F6 in Linux, and can't get my screen back

in Education by
This is obviously a stupid question. I am coding in Eclipse both on Mac and Linux, but I mixed up and used the Mac shortcut to window tabbing (Ctrl-Cmd-F6), but I was using the Linux on uni and screen went black. I've done this before, but this time I can't get back to my desktop. Ctrl-Alt F1-F6 gives me different terminals, F7 gives me a black screen and F8 a blinking underscore in the top left corner. Shouldn't my session have been somewhere in F1-F6 and is it lost?

Ctrl-Alt-F7 should work perhaps your X has crashed? I just did what you did and F7 got it back for me, saying that before I remember X crashing and I had the same black screen
