No display when TV is plugged in

[Gringo Vermelho]

The new built in injector works fine on my 9800 GTX+ running the latest drivers from nvidia - but only if I unplug the TV before booting.

If my TV is plugged in (component connection) I just get the good old blue desktop with a mouse pointer on my main monitor.

I haven't tried it with two regular monitors.

When using older injectors I used to have to use an NVCAP value that disabled the TV-out. With ATY_Init.kext I don't have to unplug the TV, and, better yet, when using NVEnabler.kext I have fully working TV-Out.

Hopefully, it will be fixed in the next release, if you like do a little thing to help and make sure, try to dump the device-properties generated by the booter, decode it and remove the "vbios" entry, then use it.

[Gringo Vermelho]

I will, if you tell me how to do it..  

I'm guessing it involves running gfxutil.

[Kabyl]

yes, use gfxutil.

[Gringo Vermelho]

 

Hmm okay, let's see if I can figure this out ... *goes googling*

1. ioreg -l -w0 -p IODeviceTree | grep device-properties > ~/Desktop/dump.txt

2. Open dump.txt with textedit, edit it to contain only the string itself.

3. ./gfxutil -s -n -i hex -o xml ./dump.txt ./dump.plist (convert to .plist)

4. Open dump.plist, delete vbios key

5. ./gfxutil -i xml -o hex ./dump.plist ./dump.hex (convert back to hex)

6. Add a device-properties string in /Extra com.apple.Boot.plist and insert the hex dump

7. Make sure the built-in graphics enabler is disabled and that there is no injector kext present elsewhere

8. Reboot

Hmm no, that doesn't work, instant reboot. I'm going to try again, I probably screwed up somewhere.

Hey Kabyl, throw me a bone here please, am I on the right track?

I'd like to help but I'm not getting anywhere with the above.

[Kabyl]

Yes, the steps are correct, can you diff the device-properties set by the booter and the one you said works best (NVEnabler)?

The .plist as generated by gfxutil using the above commands when using the Chameleon enabler looks like this:

<?xml version="1.0" encoding="UTF-8"?>

Is that right? Several lines beginning with @2 (and some other stuff) are missing when compared to another plist that I've used before - are you sure this will work when converted to a Device Properties string..?

Is there something wrong with the formatting? VRAM=Totalsize is different.. sorry to be such a noob here, maybe my gfx util parameters are wrong, I don't really know what I'm doing.

Here's one generated by EFI Studio for example:

When I do...

ioreg -lw0 -p IODeviceTree | grep device-properties > ~/Desktop/dump.txt

...with NVEnabler installed, all I get is this:

 | |   "device-properties" = {"acpi-path"="IOACPIPlane:/_SB/PCI0@0","acpi-device"="IOACPIPlatformDevice is not serializable"}
