I have an image hovering in my lock-screen that I can't remove. I think I put it there with Ubuntu-tweak but I have already uninstalled it.

Any ideas on how to remove it?

I really hope this is the only issue it left me with but only time will tell.

edit - more details

lock-screen

I think i might have replaced the "Ubuntu 14.04" logo with Darth lighting a smoke.

A - Reinstalled and set to default, and then uninstalled it again

  • The first part is solved but now it seems like I can't make any changes in my standard appearance settings.

So the new question is how to remove all traces of Ubuntu Tweak?

  • @Mohammedaadhil That worked but I still can't make any changes to my appearance in the standard settings. New question... How do I remove all traces that Ubuntu Tweak was ever there? – Jan Jan 16 '16 at 11:31

Uninstall the tweak tools using APT per the post by DnrDevil. I believe what you are dealing with is a bug in 14.04. Are you running Gnome? If so try this command and you should be able to set the wallpaper through the gnome GUI.

gsettings set org.gnome.settings-daemon.plugins.background active true

Also if you are missing desktop icons on top of this run this one:

gsettings set org.gnome.desktop.background show-desktop-icons true

Source: Wallpaper is not changing and right click does not work on desktop in Ubuntu 14.04

Open a terminal (Ctl + Alt+T) and type sudo apt-get purge ubuntu-tweak and confirm. This will remove all ubuntu tweak pakages you can also run sudo apt-get autoremove after this to remove all resources for the application.
