I noticed on an Acer laptop (Ubuntu 8.04 Desktop x86, all normal updates, Compiz enabled, Intel video chipset) when "Dim screen when idle" is enabled that the screen will dim when playing these games. A few of the games affected (because not all are) include LTris, The Mana World, LBreakout2, and Frozen Bubble 2.
