Can SOMEONE please tell me how to change the default background in Kubuntu 12.04? I have managed to select a rather nice wallpaper for my desktop, but I CANNOT change the background for the splash screen, lock screen or login screen. I am using the lightdm-kde-greeter because I think it looks nicer than the default, but as I have said, it just REFUSES to allow me to change my default, wallpaper (the grey one - why they chose grey I will never know). If I choose "classic" lightdm greeter theme it works, and I can change my login screen background but not my splash screen, and if I choose user bar I cannot even change background.
Here is what I have tried so far:
- System Settings, Login Screen (LightDM). Choose my image for the background under Classic and apply the changes, then switch to User Bar. This did not work.
- System Settings, Login Screen, disable Themed Greeter, then choose background image, and re-enable themed greeter. This didn't work either.
- Going in as root to /usr/share/wallpapers, deleting the link called kubuntu-default.png and recreating it pointing to my chosen image. This did not work either.
- Deleting my cache from /var/tmp. Again, this did not work.
Can someone advise me, I'm starting to go mad here!
