"Cannot open display" error when trying to start X Server Applications
I'm using slackware (12.2). I've been using linux before but only with a graphical interface, and I now want to "switch" to using only the terminal. I have a graphical interface installed (KDE) but I don't want to use it more than necessary (just now when I'm learning to use the terminal).
The problem is that I can't start graphical applications from the shell. When I for example tries to start firefox or XTerm I get the error "cannot open display :0".
First I got the message "no display specified" but after reading the man-pages I set DISPLAY to ":0". I've also tried setting it to ":0.0", "localhost:0" and "localhost:0.0" but nothing works.

edit: sorry for the title... I mean X Window System ofcourse. I dunno where I got "server" from
