Don't even use the "NVIDIA X Server Settings", esp. if it causes trouble.

That shows you your monitors, their connection names (before "connected", e.g. "DVI-I-1" or "VGA"), and their resolutions.</li> <li>Again in a terminal in X11, run something like "xrandr --auto --output DVI-I-2 --right-of DVI-I-1". You should see the result immediately. If it works, put that line in /etc/X11/Xsession.d/45custom_xrandr-settings and chmod 755 that file. Restart X11 and the monitors should still be in this config.</li> </ul> </ul> For more info, just search the web for "xrandr" </body> </html>
