How can I setup 1920×1200 resolutions for XFree86?

Q. I would like to setup 1920×1200 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.

Login as the root

Open file:

# vi /etc/X11/XF86Config

Since 1920×1200 is a non-standard resolution you need to locate Section called “Screen”. Then find out Modes directive of the Screen section, add 1920×1200 to the list (the beginning of the list). At the end it should look as follows:

Modes “1920×1200” “1600×1200” “1024×768” “800×600” “640×480”

Here is the complete entry:

SubSection “Display”
Depth 24
Modes “1920×1200” “1600×1200” “1024×768” “800×600” “640×480”
SubSection “Display”
Depth 16
Modes “1920×1200” “1600×1200” “1024×768” “800×600”

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