Below is the output from my Xorg.0.

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:-

sean@sean-P55-USB3:~$ xrandr

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

Did you try this?

$ sudo apt-get install read-edid
$ sudo get-edid | parse-edid

If so, what is the output of the last command? Does it give an error message?

sean@sean-P55-USB3:~$ sudo get-edid | parse-edid parse-edid: parse-edid version 2.0.0 get-edid: get-edid version 2.0.0

    OMG not bad for a Noob! Managed to write my own xorg.conf file using the steps found here grenage.com/xorg.html And with the help of my monitor manual and a bit of guesswork All fixed, Can now see all my monitors resolution and refresh rates in Nvidia control panel!! Now reset res to 1600x1200@75 I knew that you can do anything in Linux if you dont give up.

Solution Below Came from answers.launchpad.net:

In the Device section for the video card include the line:

Option "IgnoreEDID" "1"

In the Monitor section include lines for your monitor:

Horizsync 28-100
Vertrefresh 60-76

Values will vary depending upon your monitor, check the docs for it.
