Hi, I'm trying to use ptkdb to debug cgi script interactively during the browser.
I followed the instruction(see follow) but nothing prompt out when I launch the cgi script on web.

add in cgi script
#!/usr/bin/perl -d:ptkdb
sub BEGIN {
    $ENV{DISPLAY} = "localhost:0.0" ;

run xhost +webserver

Has anyone met the some problem as I do?
