I changed my login wallpaper to an image,which is different from my desktop background,using Ubuntu Tweak. When I logout/restart, it briefly displays the changed background, but fades to the old desktop background.

I believe the answer you're looking for is here.

After you follow the steps, do the Ubuntu Tweak thing.

I believe Ubuntu Tweak is not working correctly because of the Dynamic Background that the Unity Greeter has. If you try this let us know the result. Have a good day.


If I guess what you meant, it could be a problem about the owner of the file. It should be root instead of you.
