I installed ggobi on my MacBook Pro, and it wasn't working right. I looked up some information, and found this site: Gtk Warning: Cannot open display
I followed the vague instructions, but I think I just typed
export DISPLAY=:0 directly into my terminal (I'm still in my Mac partition at this point).
Fast forward a few days, and I try to go into my Ubuntu partition. It only gives me command line options. I remember my reckless input from a few days back, and I'm certain that it is the issue.
My problem is that I have no idea how to get my previous display settings back. My Mac partition seems unaffected, but it'd be nice to get back into my Ubuntu partition.
My last resort is completely reverting my computer to my most recent backup before I changed it, but if anyone out there knows how to fix this, I'd greatly appreciate it.
Thanks in advance.
