HowTo use a computer without a screen attached

The Problem:
I have a Linux machine (Fedora 14)  with no screen attached. I view the graphics via VNC server. I had to adjust the system to use the Nvidia driver and tweak it for no screen.

The solution:
First we need to install the Nvidia driver. Then, we need to adjust the X configuration for no screen and our preferred resolution.

for more details see:

1. Update the kernel:

yum update kernel*

2. Add rpmfusion to your repository.

rpm -Uvh

3. Depending on your card add nvidia akmod to the kernel and the proper driver. for a Gforce 9500GT on my 64bit machine:
yum install akmod-nvidia-260.19.36-1.fc14.x86_64 xorg-x11-drv-nvidia-libs-260.19.36-1.fc14.x86_64

4. Edit the xorg.conf file. don't forget to  adjust the Nvidia card for no screen attached by adding:
 Option "ConnectedMonitor" "CRT"
to the device section and adjust the screen resolution under the Screen section:

Section "Device"
    Identifier     "Card0"
    Driver         "nvidia"
	Option "ConnectedMonitor" "CRT"

Section "Screen"
    Identifier     "Screen0"
    Device         "Card0"
    Monitor        "Monitor0"
    SubSection     "Display"
        Viewport    0 0
        Modes      "1280x1024"
