Hello

I have problem with running wireshark

Code:

root@new-host:~# wireshark &
[1] 2677
root@new-host:~# No protocol specified

(wireshark:2677): Gtk-WARNING **: cannot open display: :0.0
^C
[1]+  Exit 1                  wireshark

I remember that i once solved this problem with xhost +
but this not working any more.
Also i have problem with festival

Code:

root@new-host:~# festival --tts speech
No protocol specified
XOpenDisplay() failed
Pulseaudio: Connection refused

Are those problem related ?

You are trying to run them as root.
If root privs are required, use gksudo or such from your regular user.

As regular user is the same (only festival eotking as regular user)
Same problem with nautilus.

I don't understand, i never used gksudo before, and i didn't have that problems.
