heb ik op deze manier gedaan :
dit is die originele instelling in lila van Ubuntu 14.04
Window.SetBackgroundTopColor (0.19, 0.04, 0.14); # Nice colour on top of the screen fading to
Window.SetBackgroundBottomColor (0.16, 0.00, 0.12); # an equally nice colour on the bottom
en door deze verandering in zwart veranderd :
Window.SetBackgroundTopColor (0.0, 0.00, 0.0); # Nice colour on top of the screen fading to
Window.SetBackgroundBottomColor (0.0, 0.00, 0.0); # an equally nice colour on the bottom
