Problem with desktop MacBook Pro

Registered
I own an older mac mini with a PPC processor, and when i set the desktop to rotate images, it does so with a smooth cross-fading transition.
On my MacBook Pro, it doesn't. I looked up the posible reasons for this...
I found that Quartz Extreme was disabled on my MacBook.
When I looked online to see how and why quartz extreme could be enabled and disabled, I noticed that this seemed to be a problem for people who are still using older PPC hardware... I would like to know why the desktop doesnt
perform this transition and how i could correct it so that it will. Please any suggestions are appreaciated. thx... also mac randomly sleeps when i close it, instead of everytime... Thanks for reading.
