Dual head with NVidia

I have my desktop spread across 2 monitors. I spent a while getting this right mainly due to installing the wrong driver first time. I have installed the Nvidia binary driver (I have an NVS Quadro4 DualHead card so for me it was the legacy-95xx kernel module and driver). Here is a copy of my xorg.conf if it helps anyone:

Make sure that you get the line

BusID "PCI:2:0:0"

to match your own system. You can find the correct X:0:0 reference number by typing lspci in a terminal and noting the numbers next to the entry for your particular card.

Dual Monitor Setup

I have an ATI card. Does it matter? I am complete new to this and at a bit of a loss as to how to make these changes, or even edit the files you're talking about.

You'll get lots of info. (now the secret is out. That is how we know everything!)

Dual Monitors

Guys I hate to bug you but I need a little hand holding here. I havn't messed with the command line of anything but 3dsmax since college(about 8 years ago) and I am quite unfamiliar with linux and the terminology used by the community. I have a single ati card driving two monitors of different types. Right now 64 Studio shows exactly the same desktop on both monitors. What do I have to do exactly to get my desktop extended around both of these monitors? I have no idea how to get to config files but I am fairly intelligent so if someone could kind of just give me the basics in laymans terms...

Thanks, Dan

ATI Dual Head

Hi there,

I used to use a Radeon 7000 to do dual head. Just make sure that the binary ATI driver is install and working then backup your xorg.conf somewhere (to restore when it goes wrong) and try to adapt your xorg.conf from this one. It worked fine at the time. I use NVidia now. Sorry I can't be of more hand holding use but a working xorg.conf would have saved me hours of messing around: #

Edited the xorg file.

I tried editing the xorg file and apparently I typed something in wrong because 64 studio wont start up now. When I boot from the live cd it won't let me edit the files on the hard drive. Before I get home today and try to figure this out on my own, any suggestions on how to get over this hump?

Single User mode

Choose Single user mode in Grub when you boot up. The enter your root password and you are in a text root terminal.

Good. Now type

editor /etc/X11/xorg.conf

You should now have a text editor in which you can edit your file again. Hope it helps a bit!

Errors

Can you give us an idea of the errors you were getting? Did the X server fail to start or did the bootup process stop before even that?

Editing xorg.conf File

Thanks guys for your help.

I'll try that this afternoon. Osaeris, question. Why is the first xorg file you posted different from the last. Which one should I base mine off of.(I recognize that the driver names will be different) In one you have two screen devices and two card devices in the other you don't.

Why 2 different xorgs?

The first xorg was for my Nvidia Quadro NVS the second was for an ATI Radeon 7000 with dual monitor support. They are quite different setups.
