Dual screen Mirror Mode

[beckend]

After about 10:ish formats i succeded in installing leo 10.5.4 amd with proper hardware support, now the only thing stopping me from using leopard as main OS is the damn mirror mode thing, which i have spent 10+ hours on googling and such.

 

is there absolutely no fix for this??

 

relevant specs are

amd x2

nvidia 8800gt 512 nvkush qe/ci enabled

leo4allv3 updated to 10.5.4

 

would it even matter if i used EFI string for my gfx? and does EFI string even work for amd machines?

any clues or help would be much appreciated.

 

Edit:

Now using EFI string and same {censored}.
