/etc/X11 : Configuration for the X Window System (optional)
Purpose
/etc/X11 is the location for all X11 host-specific configuration. This directory is necessary to allow local control if /usr is mounted read only.
Specific Options
The following files, or symbolic links to files, must be in /etc/X11 if the corresponding subsystem is installed:
| File | Description |
|---|---|
| Xconfig | The configuration file for early versions of XFree86 (optional) |
| XF86Config | The configuration file for XFree86 versions 3 and 4 (optional) |
| Xmodmap | Global X11 keyboard modification file (optional) |
Subdirectories of /etc/X11 may include those for xdm and for any other programs (some window managers, for example) that need them. [8] We recommend that window managers with only one configuration file which is a default .*wmrc file must name it system.*wmrc (unless there is a widely-accepted alternative name) and not use a subdirectory. Any window manager subdirectories must be identically named to the actual window manager binary.
