Сущестувует несколько тем, в которых рассказывают и рассуждают о различных сочетаниях настроек для появления различных эффектов, например здесь, или здесь, или здесь. В том файле, что я в итоге изменил и постарался максимально подробно оставить комментарии.

# This file contains timings and values for transitions in hildon-desktop
# duration = time in milliseconds
# zoom = amount to zoom out the background. 1 = none, 0.5 = zoom to half size
# radius = radius of blur (this is actually the number of blur iterations,
#          so the bigger the number the longer it takes)
# saturation = the amount of colour left in the background (0 = grey, 1 = normal)
# brightness = brightness of the background (0 = black, 1 = normal)
