I too can confirm this problem. I'm running a Gigabyte GA-MA78GM-S2H motherboard (780G chipset) with the built-in graphics adapter in dual-head mode and have all the problems described above. If I walk away from my computer longer than ten minutes or so, the screen will comepletely lock up. Brand new install of 8.04 just today. Used aticonfig to set up dual screens.
