How to configure xorg.conf for my 16:9 monitor?

[jinlxz]

My monitor has the 1366x768 resolution, I added the modes "1366x768" in the subsection of xorg.conf, but when I ran startx the system choosed other resolution and logged {"1366x768" no mode of this name}

I want to add modeline in the monitor subsection, but I don't know my EDID information, do anyone know how to get the EDID information on FreeBSD system, EDID didn't exist in the Xorg log file.

Later I added the modeline "1366x768" in xorg.conf using some Inaccurate values and try again, it didn't work.

Can anyone help me, thanks?

Is this virtual machine? If yes then you are limited by the virtual machine video driver.

Images of the first twenty lines of the log file is a novel but not really useful approach. What is shown suggests that you're using the vesa driver, which may not be able to do 1366x768.

Please post the full contents of /var/log/Xorg.0.log. http://pastebin.com is popular for that. It may also be helpful to know the make and model of the monitor.

Install x11-drivers/xf86-video-ati and change your xorg.conf to use the radeon driver.
