First of all, here are my specs:
CPU: AMD64 X2 5600+
Memory: 4x 1GB Kingston
Graphics Card: nVidia GeForce 8600 GTS with 256MB memory.
OS: Ubuntu Linux 7.10 (Gutsy Gibbon)
Okay, this computer is brand new, and everything works perfectly in Windows, so I don't think it's a hardware problem. I installed the NVIDIA-Linux-x86_64-169.12 driver a few weeks ago when I still had 2GB of RAM. Everything worked back then. But when I installed 2GB RAM extra, my screen went blank right before the graphical login screen would appear. I also don't hear any sounds that I usually hear when the login screen appears. It still works in Windows.
So I thought maybe it's a bug in the driver. Can anyone help me please?
