I put this post on another debian site,but no answers
the more detail information as below:
I installed lenny,then I enable the testing respositories and run "apt-get dist-upgrade" to update my OS and run"apt-get autoremove " to clean unnecessary packages.
during this period ,I found debian remove the "gedit,gdm,etc,." but in ubuntu,it never happened when I used aboved two commands to update my OS.
Now the problem is when i try to open somthing by using gedit on the shell while using root account,then the system gives errors as below
(nautilus:5245): Eel-WARNING **: GConf error:
Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://www.gnome.org/projects/gconf/ for information. (Details - 1: Failed to get connection to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)
but if I use "sudo" instead ,then everything is OK
it seems somthing wrong about the configuration of root account
I deleted .gconfd under the root folder,but no helps
and restarted dbus daemon again,also no helps
So now i want to know ,how to figure out this problem,
how to reconfigure the root account
later which command can be used to update my tesing (squeeze) system
Thanks in advance!
