Hello !

I test it , and its works but not very well but its better.

1 Question , what i need to do in the xorg.conf on :

IV.Config AMD Driver

Check if all your cards can be detected and then write configuration to /etc/X11/xorg.conf.

And

On terminal last step :

sudo aticonfig --adapter=all --odgt

I get :

ERROR - Get temperature failed for adapter 0 - AMD Radeon HD 7700 series
ERROR - Get temperature failed for adapter 1 - AMD Radeon HD 7700 series

I Have Two cards ( 7770 )

And every time I move the mouse I get a blink line on the screen ( its annoying )

If you can tell me something or someone else ! Thanks @lueo
