[jedipi 0]

under normal user, vim command (in terminal) did not have any error.However, after I su to root, vim gave me error messages

CONSOLE

why was this post made invisible ?I dont use vim, but its obviouse whats happening here, vim is trying to load an X interface.in other words, a windowed envoronment for you to type in, rather than the bash command line. But X is correctly refusing to talk to the vim program.This is because X is beeing super paranoid about securety, and only letting one user communicate with it.when you run as super user, X treats you as a different user.In theory, someone else on your network could use X to spy on your keystrokes, and see what you are seeing on your screen.to turn off this security feature, run "xhost +" as the normal user before becoming super user.anouther solution would be to use a command line text editor such as nano, or emacs. (im pretty sure vim has a command line interface too)provided that your X server is NOT listening for connections over the network, OR your firewall is blocking outsidfe access to your X server, then there is no risk in running "xhost +"to test to see if X is listening on the network, run "netstat -npl" and see if Xorg or Xfree86 is listening on port 6000.or make sure your firewall is not set to allow incomming connections to port 6000.

When you go root, run "sux" instead of "su." That should give you the correct set up for graphics through root.
