New Features

Window Positioning

10 pixels from the left and 30% down (position=10 30%)
10 pixels from the left and 30% down (position=10 30%)

With the added window positioning, the login window and power dialogs can now be placed based on relative or absolute values.

Configuration is simple. Values can be represented as percentages, positive (from the top/left), and negative (from the bottom/right). Some layout examples are below.

# position = main window position: x y

# 20% horizontally, 40% vertically
position = 20% 40%

# 10 pixels from the left, 50% vertically
position = 10 50%

# 100 pixels from the right, 50% vertically
position = -100 50%

Default User Image

The default user image configured as "#distributor-logo", useful for distributions.
The default user image configured as “#distributor-logo”, useful for distributions.

The profile image that is displayed for user’s that have not already chosen an image can now be configured.  Previously the image was always set to “avatar-default”.  The value can either be the path to an image file, or an icon name.  Sample configuration is below.

# default-user-image = Image used as default user icon, path or #icon-name

# Using a file path
default-user-image = /usr/share/pixmaps/firefox.png

# Using an icon name, distro logo
default-user-image = #distributor-logo
