2.4.3.2. ...creating the xorg.conf file without using system-config-display?
The X server itself is capable of generating a reasonable xorg.conf file, which you can then fine-tune by manually editing it:
# X -configure :1
The system will automatically start an X server using display number :0. Additional X servers can be started as long as they each use a unique display numberwhich is why :1 was used in this command.
The new configuration file will be placed in /root/xorg.conf.new . In order to use it, you'll need to link the name /dev/mouse to the default mouse device:
# ln -s /dev/input/mice /dev/mouse
You can then test the new configuration:
$ X -config /root/xorg.conf.new
This will present a blank display with an X-shaped mouse pointer. If the display looks right and you can move the pointer with your mouse, then go ahead and install this new configuration file as the default configuration:
# mv /root/X11/xorg.conf /root/X11/xorg.conf.backup
# mv /root/xorg.conf.new /etc/X11/xorg.conf
You can fine-tune this configuration either manually or by using tools such as system-config-display .
