Hi guys ,i have a problem with my graphics card ati 7850(1GB/Sapphire).
1. When I start the system in Safe Boot mode(Clover Bootarg=-x), the graphics card (HD7850) is running normally.
2. But when I start the system in normal mode,the system is blank screen.(I confirm that the signal output, see the screen because there is light.)
I am already done:
1. I have been tried Whatevergreen+Lilu,but the problem remains.
2. I also have been tried patch up Framebuffer,bue still black screen
I use CLOVER version is r4760. Only FakeSMC.kext and RealtekRTL8111.kext in the EFI/CLOVER/kext/Other folder.
My computer configuration:
radeon_bios_decode give the following result:
redsock_bios_decoder give the following result:
