Hi all!
I'm trying to enable LVDS on ATI Mobility Radeon HD 5650 on 10.7.1:

$ sudo lspci -nnvd 0x1002: | grep -B2 Subsystem

Graphics card was correctly recognized by system only after using patched Chameleon R875 boot file. Also I've forced edid file installed.

Is there any way to enable LVDS? Where I'm mistaken?

try LVDS on encoder 01 instead of 00

Unfortunately got the same result, internal display is black, backlight is on.

[jvilla]

did you change the other connection to use a different encoder?  so that they don't interfere with each other?

Yes. And not working

[itansan]

I have same 5650M. LVDS not working like LVDS, only like VGA (or DVI with analog signal = VGA ) (result display type CRT)

Take kext from 10.7.1: ATIFramebuffer, ATISupport , ATI5000Controller

See my config with working internal screen(like VGA or analog DVI) and hdmi(but like DP)







Also read my 2 last posts in this thread . What are you think about this ?

[Title101]

CheeseTank,

I have values that are identical to yours.  I am also unable to get it to work.  Have you had any further progess?

Dear gurus, could you help to find (and maybe patch) proper framebuffer for such configuration?

[ytrox]

can you at least tell us which video card you use?

Oh sorry. ATI 5650m

As far as I understand. I need to modify three lines of ATI5000Controller at offset 488680

Disk offset in decimal 488680
0000000	04  00  00  00  14  00  00  00  00  01  00  00  01  02  01  04

The last digit must correspondent with OSX sensed:. right?

First line must start with 02 00 (LVDS) right?

What else I need to modify? must I care about 0x96 and similar?

[ytrox]

to begin you have to change senseids 07, 08, 01, then follow also this topic http://www.insanelym...p...40&start=40.
you need to change a lot of things, but if you are not capable to do that you can try changing just the framebuffer of your card. you are using eulemur for now.

CheeseTank, I know this may sound counter-intuitive, but can you give this a go.  Set up the line that corresponds to your LVDS exactly as it should be according to the bios dumps - except make it a DVI port, and for the controlflags make sure it supports Analog/VGA DVI output.  Then let me know if the internal screen comes to life.  (It may be out of range by default, so you might need to vnc to set a resolution it supports, or use edid overrides).

It seems a problem many of us have (including Itansan's post above yours), where even with all the correct data edited into our ati-personality of choice, lvds simply doesn't work.. BUT we can manage to get it working as a crt/vga display.  

I really hope someone finds a *proper* solution to this soon.  There are countless posts with people having the same issue, and without proper LVDS support (instead of of the screen being shown as crt) simple things like dithering for 6-bit screens can't be enabled (i.e. the majority of cheap internal 1366x768 screens)..

[CheeseTank]

avian, tried. still doesn't work. backlight is on, but system doesn't recognize that LVDS is connected.

[mcbyte_it]

I started working to fix my video output:

• I have a Sapphire Radeon 4670 Ultimate (Passive cooling, 3 ports: VGA/DVI/HDMI), and I want to use the DVI output to my 23" monitor
  
• Using Chimera 1.5.4 bootloader, with Mac OS X 10.7.2
  
• With GraphicsEnabler=No, both DVI and VGA works good, but DVD player and geek bench crashes.
  
• With GraphicsEnabler=Yes, VGA works good while DVI is black, and everything seems to work
  
• Earlier when I used to use Chalemeon 2.0 RC5, DVI used to give a signal, but the picture was like 256 colors, maybe wrong decoder/FB

and attached to this post are the screenshots of ioregistry.

Currently my monitor is connected with both cables (VGA+DVI) but I am using the VGA input on the screen (as the DVI is blank), technically I am connected to port #0 (from the BIOS Dump), which should be at index '00000000', which has ConnectorType set as DP and ControlFlags set as DP, which are both completely wrong in my case (VGA connector), but for some reason it is giving a signal to my screen.

So, if I want to fix my DVI, I should fix line number 3 (which from the BIOS is one with the DVI ports, knowing that the radeon bios declares 4 outputs, while the KEXT driver has only 3 personalities). I should fix the FrameBuffers in the ATI4600Controller.kext by hex editing the above values to some better ones, but I don't know exactly where to change.

Currently port #2 (counting from zero) is already set to DVI ConnectorType, but the single-link one (as there is a dual link one, 0x00000004), the ControlFlag seem ok too for DVI (0x0214). this might be also confirmed by the IORegistry screen, the ATI,ActiveFlags=0x10 (Which is != 0x1, according to page 1 of this thread), maybe the features/transmitter/encoder/senseID are wrong?

As I read, the SenseID is the most important, but how to calculate it, I didn't really understand the formula, and when you say bits 0-3: are they from the left or the right?

i2cid = (senseid & 0xf-1) + 0x90
senseid = (i2cid & 0xf) + 1

Currently senseID is set to 0x04
0x04 = 0000 0100

from the BIOS Dump
  SenseID = 0x1 = 0000 0001
  i2cid = 0x90 =  1001 0000

What to do next?

Update 1:
I tried updating the port #2 to:
0000020 04  00  00  00  - 14  02  00  00  - 00  01  - 00  00 -  00  10  01  05

but now the VGA is detected with the wrong resolution, maybe the 3rd row in result of ati_personalities is in reality port #0 of the card, and that's why IORegistryView shows it is @0?

[lseba]

does any one knows in wich kext is located the conector info of the RadeonFramebuffer personality. i belive thta is the default framebuffer used when there is no match for the framebuffer injected by chameleon

[Mietas]

RadeonFramebuffer is an automatic detection of connections in graphic card. If I use this, it will detect LVDS, HDMI and VGA fine, but LVDS stay black without backlight, unfortunately.

[lseba]

so thgere is no connectorinfo hex table for radeonframebuffer that could be edited? is there a way to see the automaticly generated conector info?

Hi bcc9,

I have just come across your postings. I hope you are still monitoring this thread. I have an XFX 5770 (ZMF3) card with 3 physical connectors, DVI : DVI : MDP. When I used the tools you linked to, I found that the card BIOS reports 5 connectors:

I noticed that you were uncertain about your connector types in the original post

bcc9, on Feb 28 2011, 04:38 AM, said:

Next we take a look at the ConnectorInfo for this personality:

connector-type 0x00000400=displayport at port 0
connector-type 0x00000004=DVI at port 1
connector-type 0x00000200=single link DVI(probably) at port 2
connector-type 0x00000800=HDMI at port 3

I have to admit that I'm guessing, but there are a few clues here:

There are 3 physical connectors, but five reported by the BIOS. Logically then there must be 2 more. Then I remembered that DVI can be either DVI-D (digital only), or DVI-I (digital with -I-ntegrated analog). Looking at the output from the radeon_bios_decode tool, there's another clue in each of the 'Encoder' lines, connectors at indexes 2 and 4 have the acronym DAC in their descriptions, which usually stands for Digital to Analog Converter. Therefore I'm concluding that I do indeed have 5 physical connectors, it's just that my DVI ports are DVI-I and combine the digital and analog.

Looking at the output from your ati_personality script, I'm going to suggest that cards with DVI-I will have personalities like this:

0000000	00  04  00  00  04  03  00  00  00  01  00  00  12  04  05  01 #MDP
0000010	04  00  00  00  04  02  00  00  00  01  00  00  11  02  01  02 #DVI-D
0000020	00  02  00  00  14  02  00  00  00  01  00  00  00  00  03  03 #DVI-A
0000030	04  00  00  00  04  02  00  00  00  01  00  00  11  02  01  04 #DVI-D
0000040	00  02  00  00  14  02  00  00  00  01  00  00  00  00  03  05 #DVI-A

I'm suggesting that 00 20 00 00 is the analog port of DVI-I. What do you think?
