Dual monitors Knoppix 7.2


I'm thinking about using knoppix 7.2 as a partitioned os, but I am using dual monitors. My problem is that knoppix is mirroring the monitors. They both display the same thing mouse patterns and such. I tried looking in the monitor settings to adjust this but when I opened it there was now way to separate the two. I was only able to adjust their resolutions. Can knoppix run more than one monitor without mirroring it, and if so how? I tried to use:
'xrandr -q' and then 'xrandr --output VGA-0 --right-of DVI-0'
but I have to change the script to '--output DVI-1 --right DVI-2'
This only allows me to change the screen resolutions not seperate them, they are still mirrored.
I am using a intel i7 chip and a nvidia 460v2 video card and the VGA is not an option on my system. I only have 2 DVI ports and a HDMi port.
I have only been using knoppix on a live dvd at the moment. I don't want to install something that is not what I want. So if knoppix cannot use dual monitors then I will continue to search and try out different distros.

Thank you

I know knoppix is for recovery, but it works on my system and is really quite small. Plus it has a cool desktop.

Why knoppix over some other distro?

You can get LXDE (knoppix standard DE/WM since 6.X) on most distros if you want.

Nah, VGA is an option. I wouldnt bother, but you can use VGA, you just need a DVI->VGA adapter.

The nVidia drivers should support dual monitors even if you cant get it going with xrandr or xorg.conf hacking.

What I like about knoppix is that it works so smoothly, very smothly. I know that sometimes it can be a bit complicated for newbies to use, but at the same time it's emersion that teaches the best in my opinion, just like any other language. In the past 2 years I have just been looking around and dabling here and there to get the feel for using a pc, before that I had had 0 experience. Now I would like to pull up a seat and get into the meat of it, all or none I say. I have used other distros and like them, but with knoppix you can really mess it up fast and with only a few key strokes. It's a good teacher.
As for my video card it does great for running dual monitors, I am just having a problem with it on knoppix. I keep getting mirrored displays. I am pretty good at searching for solutions on the net now, but what I found and tried is the only solution that I can locate, and it didn't work. I would like not to have to purchase hardware.

Thank you

There is a reason you arent finding solution on the internet, knoppix can be installed to a HDD but its not a common use.

The xrandr command should work, I have no idea why it doesnt. You might be able to get dual monitors going with xorg.conf hacking. If you cant, installing the nVidia drivers should work.

But because knoppix is mostly used for liveCD stuff, and mostly by fairly experienced users, its not something with much in the way of 'install nvidia drivers' how to pages.

I believe the debian method should work.

Thank you, the nvidia driver cleaned up the problem. I now have dual monitors working nicely. Cube desktop is crazy. It's very disorientating, so I turned it off.
Again thank you for your assistance.
