so when I log into the terminal from my login screen (by typing >console as username), I get logged in to the terminal. However, when I try to use vim or anything useful, it only takes up around 1/4 of the screen, as seen in this photo (sorry for reflection!!):
How do I adjust the size of the terminal so it takes up the whole screen, rather than leaving most of the screen black? Also text colouring in vim doesn't work when in this mode, if anyone knows how to fix that too!
