milanca I also ask you for dsdt fix. I have same vga as bullys1974 but m/b is Gigabyte GA-MA78GM-US2H. I have install iATKOS 10.5.7 and have sleep issue. The System sleep fine but when I press POWER button system start but monitor remain black. Another problem is when screensaver run it's work fine but freeze when it's time for display sleep.

Thank your very much.
