The next few commits will make pantheon-wayland the default. Note that the Pantheon LightDM greeter option is left untouched right now since it still runs under X11.

The file {file}`~/.background-image` is used as a background image.
|
|
This option specifies the placement of this image onto your desktop.
|
|
|
|
Possible values:
|
|
`center`: Center the image on the background. If it is too small, it will be surrounded by a black border.
|
|
`fill`: Like `scale`, but preserves aspect ratio by zooming the image until it fits. Either a horizontal or a vertical part of the image will be cut off.
|
|
`max`: Like `fill`, but scale the image to the maximum size that fits the screen with black borders on one side.
|
|
`scale`: Fit the file into the background without repeating it, cutting off stuff or using borders. But the aspect ratio is not preserved either.
|
|
`tile`: Tile (repeat) the image in case it is too small for the screen.
