I installed xfdesktop and my login screen and background were changed to the green screen and the mouse :( I managed to change the background back to my selection, but the login screen has not changed. I looked for the solution on the forum, it said to add the selected picture into usr/share/backgrounds/ I found the folder but it does not let me delete pictures in there, it says I don't have the permission? How to get in there WITH permissions? Thanks! Fred
Here is one method for changing the login screen for Elementary OS - Juno.
- Save a picture of your choice in ~/Pictures
For simplicity sake, my login picture will be called Login.jpg (restricting the filename of your picture to a single word followed by .jpg makes this easier, but that is not a necessity).
- open Terminal via Applications -> Terminal (or Win+T)
sudo rm elementaryos-default
NOTE: Enter your login password when prompted.
sudo cp ~/Pictures/Login.jpg Login.jpg
sudo ln -s Login.jpg elementaryos-default
ls -al(check all folder privileges - everything should look identical)
- Deleting a picture in this directory can be accomplished with
sudo rm pictureName.jpgWhere pictureName is replaced with the filename of what you want to delete.
sudogives you carte blanche (read: total control) over your system. Allow me to cite Ben Parker's words of wisdom:
