How to do it from command line. I need to do it from command line because I am making a custom live CD.
on my computer it’s ctrl-alt-f7 to return to GDM…
Actually ,you may do as below :
open a terminal
type :
export DISPLAY=:0.0 (or whatever is your Display ID is)
and press enter.
then ,
type:
sudo -u gdm gnome-appearance-properties
^There We can change background image etc.
so I do everything as it says; but when I type in the “sudo -u gdm gnome-control-center” command, I get an error stating that it cannot open a connection to the session bus. What am I doing wrong here?
To use your current wallpaper for GDM, run:
sudo -u gdm gconftool-2 –set –type string /desktop/gnome/background/picture_filename `gconftool-2 –get /desktop/gnome/background/picture_filename`
Thanks, but did not work for me. After pressing enter on “sudo -u gdm gnome-control-center” it tells me:
(1744) Unique-DBus-WARNING “unable to connect to the running instance”
Unfortunately, this didn’t work at all for me… When I type sudo -u gdm gnome-control-center I get an error, and that’s all… =( Thank you for your help anyway. =)
So I’ve done it my own simple way. If anyone wants to see, I’ve written a how to which can be seen here: http://helenagunther.posterous.com/how-to-change-the-ubuntu-login-screen-backgro
Ok so, i recieved this error;
(gnome-control-center:3358): Unique-DBus-WARNING **: Unable to open a connection to the session bus: Failed to connect to socket /tmp/dbus-9nhyjP3hCY: Connection refused
(gnome-control-center:3358): Unique-DBus-WARNING **: Unable to connect to the running instance, aborting.
Not sure what this means…
