You need to figure out where DISPLAY=:0 is being set, and remove the code that does so. It's probably in your shell startup file. Depending on which shell you use, there are many possible names for startup files in your home directory: .zshrc, .zprofile, .bashrc, .bash_profile, etc.

Setting DISPLAY=:0 was correct in Mac OS X 10.4 and earlier but it has not been correct since Mac OS X 10.5.
