Help: X11Error: Can't open display
Hello, I'm getting this message on my local linux machine when I trying to run program (AFNI). I checked "echo $DISPLAY": undefined variable. However, if I ssh to the server by Cygwin from my windows machine, I can open the display (DISPLAY = localhost:10.0)
where is the problem? how do I fix the display problem on my linux server? Thank you!
