Xorg configuration

Initial Xorg configuration

• You can use X -configure, xorgconfig, or xorgcfg. I recommand to use X -configure which creates an useful skeleton file that you can then edit to suit you needs.

Keyboard Layout

• You should add the following lines to the Xorg configuration file to allow the login window (before KDE is started) to use the correc layout:

       Option "XkbLayout"      "fr"
       Option "XkbModel"       "pc105"

Note that a list of layouts can be found in /etc/usr/share/X11/xkb/symbols.

Xrandr

• With recent version of Xorg, manual configuration of the xorg.conf file is almost no longer needed. Xrandr kicks in, retrieves information from the monitor and configures Xorg accordingly.

• The HorizSync, VertRefresh, Modes and Modeline options have been deprecated (although Modeline can still be used with the Option "Preferred Mode"); the only thing that is currently needed now is the Virtual option.

• The xrandr command line is quite useful.
