the GUI NVIDIA X Server Settings screen doesn't seem to set anything that interests me.
Do at your own risk.....>>
in the menu: Go to Start/system/File tools/Fliemanager-super user mode
Fill in password....You are now root.
Back up Xorg.conf to Xorg.conf.bu
Now open Xorg.conf and scroll down to:
VendorName "nVidia Corporation"
BoardName "NVIDIA GeForce 6100 and later"
Option "DPMS" Option "DynamicTwinView" "false"
Change false to true and save the file.
Go to Start/System/Configuration/hardware/Nvidia settings
and see if that's what you are looking forAgain, it's at your own risk.
I just did the above procedure on my computer without a problem,
It shows me a picture of my monitor with resolution and a few other settings .
I am sure, if I had 2 monitors connected, it would show me both.
To put it back to original....in root...delete Xorg.config and change Xorg.conf.bu to Xorg.conf
I have played with these setting a lot , like in LOT.
You can loose your screen, but the trick is to be able to get to
your backup Xorg.conf
In case you are new to linux, may I advice you to have 2 setups: one for real, and one for play.
