I have Ubuntu 12.04 with gnome. I want to replace the background image of the screen where I'm asked to choose between Windows and Ubuntu.

I replaced this image


with another image at the same location with the same name.

But now the screen has a blank background and does not display the new image.

I use Grub Customizer to change the background image.

To install, open a terminal and enter the following commands.

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

Run Grub Customizer. Go to Appearance Settings > background image.

You should choose an image that will be available at boot time. So, I strongly recommend that you place the image of your choice in /usr/share/images/ or /usr/share/backgrounds (you have, of course, already done that).

Traceback (most recent call last): File "/usr/bin/add-apt-repository", line 125, in <module> ppa_info = get_ppa_info_from_lp(user, ppa_name) File "/usr/lib/python2.7/dist-packages/softwareproperties/", line 84, in get_ppa_info_from_lp curl.perform() pycurl.error: (56, 'Received HTTP code 407 from proxy after CONNECT') – Dhruva Jain Jan 31 '13 at 18:07
That looks like a temporary error with the server (though I could be wrong). Please try again now that some hours have passed. Remember to use sudo in front of the command. – Paddy Landau Feb 1 '13 at 12:43
