How can I setup 1920×1200 resolutions for XFree86?

Q. I would like to setup 1920x1200 resolution for my XFree86 X windows system. How do I setup in XFree86? I am using Fedora Linux v5.0.

A. XFree86 is an X server that was originally designed for UNIX and UNIX like (BSD/Linuix) operating systems running on Intel x86 hardware. It now runs on a wider range of hardware and OS platforms.

File /etc/X11/XF86Config is a server configuration file for XFree86. You need to edit this file using vi text editor.

Open file:

# vi /etc/X11/XF86Config

Since 1920x1200 is a non-standard resolution you need to locate Section called "Screen". Then find out Modes directive of the Screen section, add 1920x1200 to the list (the beginning of the list). At the end it should look as follows:

Modes "1920x1200" "1600x1200" "1024x768" "800x600" "640x480"

Here is the complete entry:

SubSection "Display"
Depth 24
Modes "1920x1200" "1600x1200" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 16
Modes "1920x1200" "1600x1200" "1024x768" "800x600"
EndSubSection

Save the file and restart the system or restart the X server by logging out (or by pressing
CTRL+ALT+BkSpace keys)
