X is a server which listens to requests for display.

Basic configurations are under /etc/X11, but xorg.conf is generally no longer used.

Examples can be found under /usr/share/X11/xorg.conf.d/

The xorg displays a section, then identifiers, then some options, then ends the section.

Display Manager

This presents login options, then starts the desktop. One is LightDM manager.

The program reads the configuration files in the order of: /usr/share/lightdm/lightdm.conf.d/, /etc/lightdm/lightdm.conf.d/, then /etc/lightdm/lightdm.conf.

The file /usr/share/lightdm/lightdm.conf.d/50-gues-wrapper.conf

X defaults

~/.Xresources and ~/.Xdefaults load basic X settings.

Xdefaults is loaded each time if no Xresources is present.

If Xresources is present, Xdefaults it ignored. Xresources is loaded with:

xrdb ~/.Xresources
