I have done a basic installation for a server.
And then I have removed the screen and the keyboard because I have no place for them so my server is blind.

I manage the server from my laptop using NX.
I am using the root user because I can't stop the server with a normal user.

I have installed the nvidia driver with the one click method.

I have used my television set as screen and configured a basic monitor :
Section "Monitor"
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Unknown"
HorizSync 28.0 - 33.0
VertRefresh 43.0 - 72.0
Option "DPMS"

Before removing screen and keyboard, I have configured some parameters with the nvidia control command panel.

Now without the monitor, the video fan is very noisy.
When I click on the nvidia X Server settings button I get this message :

"You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server."

It seems that the driver does not load because it does not found any monitor.

Any idea to set up the driver ?

Thank you for your help.
