Radeon HD 4570 LVDS/VGA/HDMI

Recommended Posts

Hi I am trying to make at least LVDS and VGA work. I have working Shrike framebuffer (output for ioreg with SSH is ATY,Shrike), but output on LVDS is like attached picture and no output on VGA or HDMI. I have tried patching framebuffer in ATI4600Controller.kext but I don't think it's working.

 

Here is modified Shrike can anyone tell me if it's wrong?

02 00 00 00 40 00 00 00 09 01 00 00 12 04 00 07 LVDS
10 00 00 00 10 00 00 00 00 01 00 00 00 10 01 01 VGA
00 08 00 00 00 02 00 00 00 01 00 00 10 00 02 05 HDMI

I have tried senseid 00 - 07 and none work for LVDS. Also have forced EDID to pick up LVDS which seems to force LVDS everytime with GraphicsEnabler=No but still nothing with GraphicsEnabler=Yes.

UPDATE: I tried DSDT injection for my card detailed here:

http://www.insanelymac.com/forum/topic/282637-ati-mobility-radeon-hd-4650-cant-find-lvds-senseline/

 

Here's the DSDT I came up with. What is wrong with it? I was getting jumbled screen again but different pattern than before, closer to solid color but still missing pixels and I was not able to log in and use VNC/SSH like usual.

Also I still couldn't get Shrike personality to work. Nothing seems to work, what else can I try? And can someone take a look at the stuff I've already done...in case I messed something up?

 

Thanks!

I just found out my internal screen connection is LVDS/eDP. There doesn't seem to be a solution at this time but does anyone know if anyone is working on development for this topic? Also, the eDP shouldn't affect my VGA so can anyone tell me why that isn't working?

I have it working so far with Cardinal personality from ATI4800Controller.kext with modified Cardinal FB but nothing shows up on screen. When I VNC in to it I get both LVDS and VGA external screens but nothing showing up on the actual screen itself. How can I get signal on VGA screen?

I was told I'm lucky for getting this far and it probably won't work since it's a Sony laptop and they do something weird with their graphics. I was also told that since RadeonFramebuffer can detect external screen I should be able to get one of the other personalities to do it as well. Maybe there is also some way to figure out how to make eDP work?

      Please help me with this 10.9.5 system. Motherboard: Gigabyte 965p-s3 rev3.3, gpu: Ati Radeon HD6450 (dvi/hdmi/vga). 
      Using any of the 3 ports on the 6450 (dvi, hdmi, vga), I see all the white letters on black background during boot but when they complete and it's time for the graphics to start I get a black screen and sometimes a restart after that. Using Clover 4411. Is there any way to get past this?

      Could you please help me enable the VGA port on the GT710 in 10.9.5 13F34 ? 
      It is currently booting fine through its HDMI port, web driver 334.0103f01 and config.plist arguments checked: Verbose (-v), npci=0x2000, dart=0, nvda_drv=1
      The nvidia GT710 works fine through its VGA port and web drivers on a friend's Mac Pro 3,1
      I must soon return this borrowed HDMI monitor, mine only has a VGA port so I'd appreciate your input.

      Hi there.
      I'm new to this site but not totally new to hack. I've had a hack since 10.4 and the latest version I ran was 10.9, not totally fixed but it worked to what I needed. Now I want to make the machine run as good as it can. I can see there has been a lot of changes/upgrades/new solutions since I installed my hack and I have a hard time to catch up.  
      I've been able to boot and install macOSX and now I need the POST installation.
      I tried to install the clover EFI boot loader with these settings:
       
      and found the DSDT.aml and SSDT-0.aml from HERE
      found the apfs.efi
      and placed it in EFI -> EFI -> CLOVER -> driver64
      and these kext in here:

       
       
      But when I boot it up this is the first bootscreen I have. No partions, no mouse control, no nothing.

      if I exit clover this screen appear.

      and now everything works. 
       
      What is wrong?
      Cheers
      Soren
