Second Monitor not Detected

Dark_Oppressor · 08-08-2006, 05:04 AM

I've got Dapper 6.06, the latest kernel, and I just installed nvidia-glx. Afterwards, I ran nvidia-xconfig and then rebooted. I now have 3D acceleration, and a full range of resolutions available, but only on my first monitor. I have a second monitor, and a 7900GT, but the driver is apparently not even detecting the second monitor. In the Display settings, the entire Monitor Orientation section is greyed out. I ran nvidia-settings, and in the sections regarding monitors, there is only one monitor listed. How can I configure the nvidia driver(or xorg.conf) to recognize both of my monitors?
I attempted to modify my xorg.conf, here is what it looks like right now(X won't start with this xorg.conf, so obviously I'm doing something wrong; I have excluded some sections such as the input devices and files)

hello

i tried second monitor with nvidia, it is some thing about the type of second display like 'clone' or something (i am in a windows pc right now). but i am sure you can find it in the nvidia help file (/usr/doc/NVIDIA.....). check out the appendices and you'll get it. once you follow the instruction, it WILL work.
