If you have the {{package|system-config-display}} package installed, you can use the ''system-config-display'' command to create a configuration file. You can run it interactively simply by running <tt>system-config-display</tt> as root (or find it in the system menus under System > Administration > Display). This may not work if you cannot run X at all. In this case, you can run it non-interactively by using the <tt>--noui</tt> parameter, like so:

system-config-display --noui

If you wish to specify a particular driver for your card you can simply create a standard {{filename|/etc/X11/xorg.conf}} file and then edit it by hand, but you can also do this directly with ''system-config-display''.

<pre>

system-config-display --noui --set-driver=nv

When using the <tt>--set</tt> parameters, <tt>--noui</tt> is implied, so you do not really need to include it. For more information on ways you can use ''system-config-display'', run <tt>system-config-display --help</tt>.

Fedora releases since Fedora 10 do not create a /etc/X11/xorg.conf file, used to configure the X server, by default. The X configuration is automatically determined each time X is started. In most cases, this works well and there is no need to manually specify X configuration information.

If you need to make manual changes to X configuration for any reason, you will first need to create a /etc/X11/xorg.conf file.

[edit] Xorg -configure

You can create a basic xorg.conf using the X executable itself. As root run: 

Xorg :1 -configure

This will create the file /root/xorg.conf.new, which you can then copy to /etc/X11/xorg.conf: 

cp /root/xorg.conf.new /etc/X11/xorg.conf

and edit according to your needs.
