Gtk-WARNING **: cannot open display - I think X Is broken

Rebooted my Debian laptop:-

Reboot, back into scott

Opened up xterm

Typed: Perl

**** is a wireless sniffer with a nice gui******

A dialogue box came up, saying this must be run as root.

Changed into root vi su -

And then got the error.

Fri Jul 4 20:12:47 2003 Gtk-WARNING **: cannot open display:

Anyway, did abit of investigating

If I loginto root, I can run the program, it just seems i cannot run any programs under root while logged in as user scott.

I have tried both unset DISPLAY & Export DISPLAY=:0 and still wont work - I dont get any erros aswell when I run them.

Now, I have also tried xhost +localhost

If I log in as root and try that command in xterm - I get bad hostname, but it will take

If I then log in as scott and in xterm, I then do a Su -, type 'xhost +localhost I get: unable to open display ""

Any ideas?

Just bumping this to the top. I have similar problems and would like to know where you should check the XServer perms.
