The current implementation of the fading code is taken from gnome-session. It's not optimal since it computes the blending for each pixel. This can be done faster by using a 256 byte lookup table which is precomputed for each fading step.

Another issue is that hte fade code doesn't work with multiple screens. There is a patch in ubuntu for it but it only fixes fade out but not fade in.

I'm attaching two patches that should fix both issues. Please review my code as I'm no expert on gnome/gtk programming.
