Pessoal,

Eu preciso iniciar uma aplicação como root mas no ambiente X de usuário... mas eu não estou conseguindo pois dá a seguinte mensagem quando executo:

Code:

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified


Gtk-WARNING **: cannot open display: :0.0


Não tenho idéia do que devo fazer.... para que não haja essa restrição de uso?

Obrigado,

-ruina

Por um momento pensei que era um post em inglês... hehehe

Eu tb tive isto qdo tentei dar um xconfig (não sei porque, já que uso o menuconfig...) do kernel.

Para isto, volte a ser o usuário que logou no X e rode o comando com sudo. Para isto, vc tem que estar no /etc/sudoers .

Para dar make xconfig, vc precisa fazer o seguinte:

Code:
sudo make xconfig

e entrar a sua senha.

Good luck, man!

Pilla: Esse método é um pouco mau pois abre uma série de buracos.

Code:

humpback@sam humpback $ su -
Password:
sam root # xauth merge /home/humpback/.Xauthority
sam root # xeyes


Neste momento já deve aparecer uns olhinhos :)

Caso nada apareça (e este método é ainda mais limpo):

Code:

humpback@sam humpback $ su -
Password:
sam root # export XAUTHORITY=/home/humpback/.Xauthority
sam root # xeyes


Em alternativa (mas que come muito mais CPU) é alterar a configuração do sshd para aceitar ligações como root e:
Code:

humpback@sam humpback $ ssh -X root@localhost
root@localhost's password:
Last login: Sun Aug 31 01:33:50 2003 from localhost
/usr/X11R6/bin/xauth:  creating new authority file /root/.Xauthority
sam root # xeyes


A melhor forma é mesmo a segunda.

Code:

priss root # export XAUTHORITY=/home/humpback/.Xauthority
priss root # mtr www.uol.com.br
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Gtk-WARNING **: cannot open display: :0.0

substitui export XAUTHORITY=/home/humpback/.Xauthority por export XAUTHORITY=/home/meuhome/.Xauthority :)
(se o seu home for "humpback" desconsidere :? )
