I have a picture which I want to set as desktop background, and I want it to stay the background image even when I restart my computer (I don't want to set it every time manually, from system settings -> apparence -> background).

Please help me, I used ubuntu tweak for the login screen logo, but I can't figure out how to change the desktop background "forever".

Many thanks!

    That is extremely odd behaviour. Normally it should stick if you went through the System Settings -> Appearance -> Background route. Are you logged in as a guest?

  • No, I'm logged in with admin account (the one with password) Apr 30, 2013 at 9:01
  • and I assume you logged in as admin (root) after restarting?

  • It doesn't stay at me... I'll restart it again now, to see, but I already tried this for 3 times. Apr 30, 2013 at 9:02

Solved. It is related to the use of encryption of the $HOME folder. The wallpaper is loaded before the login process, not after you log in. Therefore, if your wallpaper is stored in your home directory, and if your home directory is encrypted, the login system is not able to read it. To solve this issue, simple store your wallpaper image in a non-encrypted home folder, let's say in /etc, and choose it as default wallpaper as described above.

Here is how you change your background:

1.Right click on the desktop, and click on Change Desktop Background. Notice the purple background in the image below the menu.

2.Choose an image from the displayed images, or add one of yours by clicking on the + sign.

3.I choose the image that is pointed, and you can see that the background image has changed, and after re-booting the image stayed the same.
