Hi guys, I got problem with my VideoCard.

My System is,

CPU T2330 Intel Pentium Dual-Core

Chipset ATi RD600

Graphic nVidia GeForce 8400M GS 256MB [DevID : 0427 VenderID : 10DE]

HDD HITACHI 500GB (I partitioned 400G to NTFS for WIN7, and 100G to NFS+ for Leopard]

And I just installed Leopard 10.5.02 with speedstep kernel on this system.

As you know, This is laptop manufactured by SAMSUNG, and Model is G25(I bought it from Republic of Korea)

Anyway, After Installing Leopard, I downloaded 'NVidia-Leopard-Graphics-Kexts.pkg' and 'NVkushInstaller.pkg' and I installed both.

And I reboot my laptop.

Everything worked perfectly before the end of gray background apple logo loading screen.

After that, My Laptop's LCD just blacked out! But I can hear the voiceover sound.

And then, I connected Monitor via VGA, and I rebooted.

And I can see the MAC OS X via VGA Monitor (But Color was inverted So I fixed with Ctrl+Opt+Cmd+8),

But I can't see anything via Laptop panel. It just keep blacked out.

So I googled about that. And I tried tried tried.... All fails.

Last, I found the final note about this kinds of bug(?) in here, But The kext link was broken.

What Can I do now? Please help me. VGA Monitor is not mine, So I have to give it back to David tomorrow.

----here is my problem (simple, no story)----
