Getting black screen at login with my new monitor (Solved)

[srb.rastogi]

Hi, I have been using my Hackintosh (iAtkos OS X 10.5.8) for about 8 months now and every thing was running fine until now. I have just received my Dell 22" UltraSharp 2209WA monitor to replace my old Viewsonic 15" monitor. After setting it up I all I get is a black login screen but everything seems fine before that... I get the bios screen, chameleon works fine too, and I can see the round grey logo spinning while the os is loading.

 

But I can boot fine in the safe mode. In safe mode my monitor is correctly recognized and proper native resolution of 1680x1050 is detected and selected by default. I don't know why I am getting a black screen at login in normal mode.

 

I have already added

<key>Graphics Mode</key>

<string>1680x1050x32</string>

to the com.apple.Boot.plist but that doesn't help.

 

I have also read somewhere to change the value of @0,display-cfg from <ffffffff>to <00> but when I open my NVEnabler Info.plist file I cant find anything like that. By the way I am using Nvidia GeForce 6600 256MB graphics card. I am pasting the content of NVEnabler plist file:

Please help!!! Although I am not a beginner but this thing seems to be beyond me...

 

---EDIT---

Ok I solved it myself by upgrading my Chameleon bootloader from RC2 to version RC4. Now everything is fine and my monitor is working.
