When setting a wallpaper in Ubuntu 17.04 I could choose from tile, zoom, center, scale, fill or span options.
Where can I found option for 'center' wallpaper behaviour in Ubuntu 17.10?
Background: I use two monitors with different resolutions. So I was more than happy to use small image as a wallpaper with white colour filling the rest of the screen.
This was done through All Settings -> Appearance -> Look tab in Unity, where I could select option "center" and white colour to fill the rest.
After updating to Ubuntu 17.10 I was not able to select my custom wallpaper from Background -> Wallpaper menu, so I went to the directory with the image and tried to "Set as Wallpaper" option in the menu, but it zoomed image to every screen resolution (it looks awful).
So I wonder - How can I set wallpaper to be centred without zoom and to use plain white colour for all the space left?
