X-Gray Posted February 24, 2014 Share Posted February 24, 2014 hi I have 6570m/5700 series ..I got my LVDS screen to work on mavericks but with no Backlight ... it's detected in ioreg as AppleDisplay not AppleBacklightDisplay. what I did : first of all I'm using ATI5000Controller.kext I'll try 6000 sometime just to get the backlight working. my radeon bios dump Connector at index 0 Type [@offset 45278]: LVDS (7) Encoder [@offset 45282]: INTERNAL_UNIPHY (0x1e) i2cid [@offset 45352]: 0x96, OSX senseid: 0x7 Connector at index 1 Type [@offset 45288]: HDMI-A (11) Encoder [@offset 45292]: INTERNAL_UNIPHY1 (0x20) i2cid [@offset 45375]: 0x90, OSX senseid: 0x1 Connector at index 2 Type [@offset 45298]: VGA (1) Encoder [@offset 45302]: INTERNAL_KLDSCP_DAC1 (0x15) i2cid [@offset 45402]: 0x97, OSX senseid: 0x8 so I patched the FB "Eumelur" to look like this 02 00 00 00 14 00 00 00 09 01 00 00 10 02 01 07 // fully working with acceleration. other tries : 02 00 00 00 40 00 00 00 09 01 00 00 10 02 01 07 // black screen even in ioreg no display detected 02 00 00 00 00 01 00 00 09 01 00 00 10 02 01 07 // same as above even after this patch I got a black screen .. so I added edid using this guide.I hope this helps somebody .. and someone to help me with the backlight issue proof 1 Link to comment Share on other sites More sharing options...
freeuser16 Posted February 25, 2014 Share Posted February 25, 2014 You have to add Device(PNLF) to your DSDT to get backlight adjustment working (if that's the problem). This can be done automatically in Clover or manually in Chameleon. Please also check if you don't have gradients issue, it happened on some 5000 series cards using this EDID injection method.

Macken Posted February 26, 2014 Share Posted February 26, 2014 X-Gray, I've also got a notebook with a 6750M Radeon card and I mentioned the problems I was having with it here: http://www.insanelymac.com/forum/topic/296101-samsung-chronos-7-and-radeon-6750m-problems/ Mine's a Samsung Chronos 7 and it's stuck at 1024X768 and it's using the fit to screen to fill things out but the native resolution is 1600X900 and I'd really like to get that working. Do you think the method you've used would help my issues? I've tried a lot of things and from what I've read in the guide you linked to, it looks like it may be fairly straightforward. Sorry I can't help you out with the backlight issue. Link to comment Share on other sites More sharing options...

Thank you for your reply .. I already have PNLF device in dsdt and yes I have gradients issue .. what should I do I tried booting with PCIRootUID=1 the screen didn't work. X-Gray, I've also got a notebook with a 6750M Radeon card and I mentioned the problems I was having with it here: http://www.insanelymac.com/forum/topic/296101-samsung-chronos-7-and-radeon-6750m-problems/ Mine's a Samsung Chronos 7 and it's stuck at 1024X768 and it's using the fit to screen to fill things out but the native resolution is 1600X900 and I'd really like to get that working.

Sorry I can't help you out with the backlight issue. I'm sorry I have no idea that this will work for you or not ... have you tried injecting EDID.. ? screens with resolution higher than 1366X768 must do something with DualLink .. I know nothing about that.. since this is my second hackintosh build and also my poor experience Link to comment Share on other sites More sharing options...
freeuser16 Posted February 27, 2014 Share Posted February 27, 2014 Inject EDID with Clover, using InjectEDID=true to avoid gradients issue. But make sure you have an original DisplayProductID-717 file. Macken, you have Intel HD card. In such case, Radeon will not work. You can enable and use Intel HD only.

freeuser16 Posted February 27, 2014 Share Posted February 27, 2014 Exactly, it might be because of bad transmitter/encoder values. But gradients are caused by wrong EDID injection method. Link to comment Share on other sites More sharing options...
X-Gray Posted February 28, 2014 Author Share Posted February 28, 2014 Thanks for your replay I'll try that and post the result today. this is my biod decode Connector Object Id [14] which is [LVDS] encoder obj id [0x1e] which is [iNTERNAL_UNIPHY (osx txmit 0x10 [duallink 0x0] enc 0x0)] linkb: false Connector Object Id [12] which is [HDMI_TYPE_A] encoder obj id [0x20] which is [iNTERNAL_UNIPHY1 (osx txmit 0x21 [duallink 0x1] enc 0x3)] linkb: true Connector Object Id [5] which is [VGA] encoder obj id [0x15] which is [iNTERNAL_KLDSCP_DAC1 (osx txmit 0x00 enc 0x10?)] linkb: false Link to comment Share on other sites More sharing options...
X-Gray Posted February 28, 2014 Author Share Posted February 28, 2014 Exactly, it might be because of bad transmitter/encoder values. But gradients are caused by wrong EDID injection method. Is there any other way to fix gradients ? because I'm not using clover. Link to comment Share on other sites More sharing options...
freeuser16 Posted February 28, 2014 Share Posted February 28, 2014 You can enable the card in DSDT and inject EDID there. But believe me, using Clover is much much easier Link to comment Share on other sites More sharing options...

But believe me, using Clover is much much easier okay ... is it safe to move from chameleon to clover ?? note: I'm using edited dsdt and ssdt.aml for my cpu states Link to comment Share on other sites More sharing options...
freeuser16 Posted March 2, 2014 Share Posted March 2, 2014 Why not? You can generate processor states in Clover automatically, without SSDT. Link to comment Share on other sites More sharing options...
