External monitor issue...help needed

[kartveli]

hi all,

trying here to set external monitor with my laptop so i could enjoy working with resolution 1680x1050.
i did as follows:
1. hooked up monitor to laptop
2. launched (root) nvidia-settings
3. detect displays (goes well) -> set them as "separate X screen"
4. safe to xorg -> quit
5. reboot

after reboot:
- on external monitor i see boot process -> nvidia splash...and then it goes dark...
- laptop monitor dark as well
only way to login is to unplug external monitor and "ctrl alt backspace" to restart X.
this is part of my xorg concerning monitors and nvidia:
