Nvidia LVDS / internal display cards [nVidia M cards]

[deadreaper]

There are a lot of people out there with nVidia M (mobile) cards connected via internal display / LVDS without qe/ci.

 

Such a configuration occurs mainly in laptops and All in one PCs

 

In such a case none of the existing kexts....or the graphics enabler from chameleon will work !

 

hence there are 2 alternatives...either use an EFI string or edit in DSdt

 

the problem with using an EFI string is the NVCAP ....does anyone know of an NVCAP for LVDS display or internal dislay connector?

 

DsDT has always been a trouble for me....hence i do not know about that

 

If there is any other way ..please post it here

 

If anyone can make a kext , then this would be greatly appreciated

 

Please help in getting the LVDS display to work

Please help in getting the LVDS display to work

LVDS is present on all laptops and it has never been an issue.

If you have a problem, it's elsewhere.

My apologies for resurrecting an old thread, but I am having the same issue trying to get the internal monitor of my Fujitsu-Siemens E8410 functioning properly.

 

This is my second hackingtosh installation (the first being a Dell Dimension 9200/xps 410) where I had to re-flash the cards BIOS and use a gfx-string in order to get QE/QI functioning; in addition to booting into 32-bit. (the card was a Quadro 4500)

 

My problems with the laptop installation, however, is that I am only able to get 1024x768 w/o QE/QI on the internal LVDS panel--and that only when not using any injectors (tried NVEnabler and GraphicsEnabler=Yes in "Chimera 1.7.0")

 

I have read that in order to use resolutions higher than 1024x768 one has to enable Dual-Link in the DSDT (the property 'AAPL00,DualLink'). I am not sure though if this applies to Nvidia hardware as it was Intel HD3000 specific.

 

What I am referring to is the --

 

Method (_DSM, 4, NotSerialized)
		{
			Store (Package (0x02)
				{
					"AAPL00,DualLink",
					Buffer (0x04)
					{
						0x01, 0x00, 0x00, 0x00
					}
				}, Local0)
			DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
			Return (Local0)
		}

 

Section to be inserted right after

 

Device (GFX0)
		Name (_ADR, 0x00020000)

 

in the DSDT.

 

Problem is that my own DSDT did not have the GFX0 device so that info has been added also (the "Nvidia" section of the DSDTSE). Unfortunately though, my DSDT edits do not seem to have any impact, and I am therefore wondering whether I am on the right track or completely off. (I've also tried use the gfx string method, but have not found examples of using an LVDS in place of DVI/VGA in the NVCAP.)

 

btw., the behaviour is the same in Snow Leopard and Lion (10.7.2)--only the external display is usable.

 

Now, obviously there isn't much point in running OS X on a laptop when one can only use an external monitor (hooked up via DVI on the docking station/port replicator); unless of course the laptop is basically used as a stationary system.

 

Since a lot of stuff works properly -- QE/QI with full res., audio, USB ports, webcam, etc, it would be nice to get the internal LCD up an running as well, so I will highly appreciate if someone on this board have any ideas to get it running (been wrestling with this problem for a couple of weeks now)

I've also tried extracting the EDID data from Linux (in order to insert into the plist before generating the gfx string hex); however the only EDID I get is the one for the external monitor; which of course works fine.

 

Surely some of the more experienced members on this forum would have some suggestions on how to get this working? This laptop can't be the only one with this issue.

 

Also got the synaptics trackpad and on-board keyboard working now (with the exception of the "Win"/"Apple" and "Alt"/"Option"(?) keys being switched around.

I have the same issue... Since 4 years with my VAIO FZ21M (with Nvidia 8400M GT)... And no one here seems to have finded a proper solution

It's a lot of months now that I'm not trying OSX. Anyway mine is the common VAIO's LCD black screen issue when enabling graphics. BTW it works only in VESA mode.

Lion too.
