cannot connect to X server :0.0

[Sylwester Gruszka]

niestety coś nie jest okej:

[root w mr_momo ~]# export DISPLAY=127.0.0.1:0
[root w mr_momo ~]# kcontrol
kded: cannot connect to X server 127.0.0.1:0
DCOP aborting call from 'anonymous-25916' to 'kded'
kded: ERROR: Communication problem with kded, it probably crashed.
kdeinit: Can't connect to the X Server.
kdeinit: Might not terminate at end of session.
kcontrol: cannot connect to X server 127.0.0.1:0
DCOP aborting call from 'anonymous-25902' to 'kcontrol'
ERROR: Communication problem with kcontrol, it probably crashed.

to jest efekt kiedy wpisuje wszystko w "konsoli administratora" bo jak
wpiszę "sudo su -" to mam "sorry - wrong password, try again" (a jestem
w grupie wheel).
