El siguiente error se produce al bootear linux.

"
There was an error starting the GNOME Settings Daemon.

Some things, such as themes, sounds, or background settings may not work correctly.

The last error message was:

Failed to connect to socket /tmp/dbus-E5LfJ0BbwA: Connection refused

GNOME will still try to restart the Settings Daemon next time you log in.

Solucion
Cito:

i found 2 solution.

1. add two line in file /etc/network/interfaces:
auto lo
iface lo inet loopback

and commenting out all entries with IPv6
then type sudo ifup lo on terminal
and reboot linux box (ubuntu 7.04/feisty fawn)

2. Go in the sound preferences and disable ESD

Then i use the first solution, and it works. So if you have the same problem, just do 2 solution above, and i hope it works to you too.

Ubuntu: WPA WIreless

Referencias:

• http://www.debianadmin.com/enable-wpa-wireless-access-point-in-ubuntu-linux.html

Cito:

"

To update the source list run the following command

sudo apt-get

sudo apt-get install wpasupplicant

sudo apt-get install network-manager-gnome network-manager

sudo gedit /etc/network/interfaces

Comment out everything other than “lo” entries in that file and save the file

Create a file called /etc/default/wpasupplicant, add entry ENABLED=0 and save the file

sudo touch /etc/default/wpasupplicant

Reboot your system or use the following command

sudo /etc/init.d/dbus restart

Once you login back in to your machine you need to left-click the network manager icon in Gnome and select your wireless network It should prompts for password, type, etc and It will ask you to choose a password for your new “keyring”.
