First off, I just want to say that I'm really new to computer programming... having a Mac is making this 10x more difficult because nobody here is familiar with Macs. So like 5 days ago, I opened up Terminal and connected to our school's server and I managed to open up gedit and start writing a program. However, yesterday when I tried to open gedit again and any of my .cpp files, I got (and have continued to get) the follow error: "(gedit: #####): Gtk-WARNING ** cannot open display:" The ##### digits are different every time I try. I also tried using X11 and I got the same error. Does anyone know how to fix this? Or what's even wrong? All of my classes' TAs are not familiar with Macs and my professor has yet to respond. Thanks. Also, emacs doesn't work either. I can get emacs to work on X11 but I don't like emacs slash I can't figure out how to save on it.
