running dual head monitor

[snazyevey]

I have been trying to get dual head to work in fedora 8

i have one monitor running at 1440x900 and the other one is my lcd tv that i want to run at 1920x1080.
however, after playing with resolutions and dropping both qualities down to something more managable (or so i thought) i am still not having any luck
when i boot up i just get one monitor black and the other one is just distorted with horizontal coloured lines running through it?

i am using a xfx 7800gt oc video card, nvidia...

is this even possible and if it is what am i doing incorrectly and what can i do to get this to work properly??
thanks for your help!

First before anything, make a backup file of your xorg.conf

cd /etc/X11/
cp xorg.conf xorg.conf.bak

-----------------------------------

Try this as xorg.conf and when its done press CTRL+ALT+BACKSPACE to restart X.

i tried to login as root and i get in but it keeps kicking me out right away..is there any other way....
is it possible to change the user rights as a user to make me able to read write to the etc folder...
and how would i do that?

First off, make sure you are logged on as root when you make the changes. I've had no luck as a regular user getting my set up to work.

Here is my xorg.conf:

It looks like you are not running the right driver. the driver called "nv" is sort of a generic driver. Install the driver from Livna. You can follow the directions here: http://www.fedorafaq.org/#nvidia

After the reboot, log on as root and make the configuration changes (resolution, twinview, etc) using the nVidia configuration tool. It's in the system menu. Because you want to use two different resolutions, you must use two seperate x screens. AFAIK.

thats true i didnt check that... the driver..

try t download the propietary driver.. i did it and works for me but when you install it be sure you are not on gnome...on shell as root type init 3 to boot as multiusermode in case you have init 5 as default (X11)....

then install the nvidia driver.. once its done.. then enter as root to x11 using "startx" (as root).. and you can easily config with a nvidia GUI tool...

If you are trying to make both monitors work with compiz-fusion... wont work.. you need to change more things.

I have an Alverto NVIDIA GeForce 5500 PCI 128 MBs VRAM and I am also trying to run Dual Heads, but on FC7, do I do the same? Only the first monitor works, when I configure my second it fails to start the X Server at boot time. Although I do have the main Video Card Chipset included on the motherboard a Intel Pro 8 MB, not good, but that one seems to be accepted as second adapter.
