Since i installed BackTrack on my computer,just before i start Wicd Network Manager,i oftenly got error or message like this "could not connect wicd d-bus interface. Check the wicd log for error messages"
This is might because the failure of configuration comes with BackTrack. Dont worry much,this can be fix easily wish a few commands. It need to reconfigured.
Open your terminal.Make sure you are login as root then run this command
"update-rc.d wicd defaults"
Reboot your BT to see the effect :D
NOTE: You may refer to this post about my specs i am running
