I have searched all over, and followed lots of dead ends and unanswered questions on this issue. I need to get this monitor recognised so I can use the native resolution of 1600x1200. The Nvidia driver in Windows has no problem with this. The monitor is an old Iiyama HM204DT A. Is there a way of configuring Xorg manually to get these working?

I have tried xrandr but this will not work. Output:-

Tried Nvidia Xorg.config:

sean@sean-P55-USB3:~$ sudo nvidia-xconfig [sudo] password for sean:

Using X configuration file: "/etc/X11/xorg.conf".

VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf. Device section "Default Device" must have a Driver line.

Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.nvidia-xconfig-original' Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup' New X configuration file written to '/etc/X11/xorg.conf'

How do I insert a driver line?

This is a bit of a pain as I want to use my Vectorworks cad program in a WinXP Vbox at 1600x1200 but all virtual drives are restricted to the host screen resolution.

Do i need to manually create EIDI info in Xorg?

I am slightly confused about how Xorg and Nvidia relate

Please help
