Hi

My system is CentOS 6. I need to edit xorg.conf. But it can’t be find in /etc/X11. Where is it? How can I get the default setting?

    /var/log/Xorg.0.log will tell you which configuration Xorg is currently
    using, which devices are autodetected etc. If you need to change only
    particular parts of the config, you can drop a .conf file with the
    corresponding Section into /etc/X11/xorg.conf.d.

    E.g. if you needed a UK keyboard instead of the default US, you could use
    something along the lines of

    # cd /etc/X11/corg.conf.d
    # cat keyboard.conf
    Section “InputDevice”
    Identifier “Keyboard0”
    Driver “kbd”
    Option “XkbModel” “pc105”
    Option “XkbLayout” “gb”
    EndSection

    The latest, most Wonderful ™ version of xorg doesn’t seem to require
    one – it does it all at boot.

    That being said, I think this is a stupid idea. For example, most folks at
    work I know of have two monitors, and I’ve yet to see any automatic
    do-it-at-boot figure that out.

    But, as has been said, hasn’t it just been replaced by /etc/X11/xorg.conf.d/
    There seems to be a general movement to replace *.conf by *conf.d/ .
    I’m not sure of the rationale behind this change.
    Is is Linux-wide, or is it a RedHat speciality?

  • If you know what you need, adding a separate conf file
    in /etc/X11/xorg.conf.d/ is the cleanest way to go. If you need some
    type of custom setup, however, you can generate an xorg.conf using “Xorg
    -configure”. The X server must not be running when you do this.

    ## Go to run level 3

    init 3

    ## Generate xorg.conf

    Xorg -configure

    ## The configuration file will be stored in “root” user’s home (/root)

    “init 5” to test. You can test your changes by jumping in and out of run
    level 5.

    -configure

    When this option is specified, the Xorg server loads all video
    driver modules, probes for available hardware, and writes out an
    initial xorg.conf(5) file based on what was detected. This option
    currently has some problems on some platforms, but in most cases it
    is a good way to bootstrap the configuration process. This option is
    only available when the server is run as root (i.e, with real-uid 0).

    Running FC-16 from an external hard disk that I carry back and forth between
    home and work. FC-16 boots just fine on two different laptops each with an
    external monitor attached. On the work system Xorg auto-detects the monitor
    configuration and just works. On my older laptop at home I have to run xrandr
    to get it to sort out which display is where. The work laptop is all Intel
    including the video and the home laptop has an AMD CPU and ATI graphics plus the
    display geometries are different for both the laptops and the external monitors.

    I appreciate that this is with FC-16 instead of CentOS but you may find that the
    autoconfiguration will work this well when RHEL/CentOS 7 gets built based on FC.
    It’s really nice to just be carrying the external disk between work and home
    instead of the laptop.

    Cheers,
