Help for next step: Sleep, Graphic acceleration and?

[trestar]

Hello! 

I have install Yosemite in my system:

 

CPU: i5 4590 3,30ghz

Main: MSI Z97 PC MATE

Graphic: AMD HD7950 3gb

 

Bootloader is UEFI with CLOVER.

The system boot up perfectly, is very stable 24/24 for one week,

but now I want to perfecting the system but I have not figured out how to do.

 

- 1 Sleep/awake don't work, after sleep the display turn on in Yosemite, i can move the mouse but it's all freeze, can't click on everything. 

- 2 Graphic Acceleration, I did some benchmark, it's obviously without hardware acceleration. i think it's linking to quick time and itunes video crash and VDA acceleration. The card is perfectly identify from Yosemite, so what i must do? 

 

If i understand correctly a must do something with DSDT (even if i use Clover?).... Please, help for the next step, i've read ton of posts, but i need some help to go on.

Thanks!
