nVidea 9800 GTX+ won't work

[taralex]

I'm having a strange problem: my video card seems to start but there is no picture.

I tried NVenabler (which worked fine on 10.5.7 btw), when booting with -v option, I can see that the kext starts up and recognizes the videocard, then the system starts and I see black screen instead of the desktop. The disk is doing something for a while and the whole system looks alive, but the display is blank.

 

Then I tried to delete the kext and add the EFI string, and the result is absolutely the same: blank screen, but seemingly alive PC, or Mac in that case.

 

I assume both methods work, it's just some stupid little thing that I'm missing.

Can somebody help me, please?

 

The video card is PNY GeForce 9800 GTX+ 512M.

Use the monitor output closest to the motherboard.

 

What device ID does your video card have? Mine has 0612 and works great, analog TV-out, dual DVI, mirroring, the works (HDMI untested, probably doesn't work, ref.: http://www.insanelymac.com/forum/index.php?showtopic=214129 ).

 

It works with Chameleon's GraphicsEnabler=yes and device ID inserted in NVDAResman.kext. 0612 is already present in NVDANV50Hal.kext. If your 9800GTX+ has a different device ID you might have to add it manually.

I tried both outputs - the result is the same... Mine doesn't have a TV-out. My tv is connected directly to the DVI output with an HDMI cable. I'm actually using my TV as the monitor.

I'm not sure about device ID, I just used x86tools to add the EFI string and got the same result as with NVEnabler. I don't know how to insert device id to the NVDAResman.ket or set GraphicsEnabler=yes, but I'm gonna google it now, thank you, I will try that.
