    Not sure whether you can disable it as such. Maybe there is a secret terminal code out there?

    However a sort of workaround may be to enable 'filevault' which encrypts all your files and data, and I believe as a consequence disables the login background. However it can take a long time to encrypt everything and time machine backups are handled a bit differently.

    Maybe someone else can be of more help.

    If I recall Onyx has some login screen setting.

    Loginox used to work for Mavericks: maybe dig through the binary to find what files it changes and see if those files are still in-use.

    In settings, can change login type from icons (username specified with spot for avatar) to text boxes where you have to enter username and password.

    Filevault will give a grey screen, but you get the icon logins.

    And don't think lock screen or screen after sleep will be "blank": will get blurred wallpaper and or blurred default Yosemite wallpaper (seems like that might be a semi-regular occurring bug).

    I had a look at Onyx and it does have a login screen setting, however this feature is not available in the Yosemite version.

    I checked in Snow Leopard and the login background can be changed using Onyx or manually at "System > Library > Core Services > DefaultBackground.jpg"

    However I could not do the same in Yosemite.


    Also you can change your desktop image to 'solid colour' in System Preferences which will make the login screen a solid colour similar to Mavericks.

    Possible Solution

    Through some trial and error I have discovered a possible solution!

    As I said before, if you set your desktop wallpaper to a solid colour (grey if you like), it will then make the login window a solid colour too (like Mavericks)

    However if you don't really want to be looking at a boring solid grey desktop and still want to have the full effect of transparency in the sidebar etc then follow the steps below:

    Firstly make sure you have set the desktop image you want as your default wallpaper.
    Then go into mission control and make sure there are more than 1 desktops available - Make however many you want.

    Now go back into mission control choose desktop 1 and change the wallpaper to solid colour (grey). This should change just this wallpaper (and any new desktops you add), but not any of the other ones you have already made.

    Now drag desktop 1 (grey) to the end. Now switch desktops and enjoy your wallpaper while also having a plain login window.

    I have tried this myself and restarted the computer to make sure it sticks. The only exception is when quick switching between users you may get a transparent image. However when switching to Login Window or at startup the login window remains solid grey.

    I hope this is of help. Let me know how it goes.

    How to change / disable login window image

    Not sure if you are still trying to achieve this. The method below works and is probably more permanent / satisfactory then the instructions I gave above. You can use solid colour/grey or even non-blurred image for login window without effecting your desktop wallpaper.
