Editing 963: X11

{{w|X_Window_System|X11}} is the X window system (commonly X Window System or X11, based on its current major version being 11). It is a computer software system and network protocol that provides a basis for graphical user interfaces (GUIs) and rich input device capability for networked computers.

The X11 stacks are usually implemented using a display server. The reason that it is called a display server is that the actual viewer and the server do not need to be on the same system; X11 frequently runs over a network connection. This adds considerably to the complexity of the mechanism.

Most UNIX-based operating systems, including many {{w|Linux|GNU/Linux}} distributions and the {{w|Berkeley_Software_Distribution|BSDs}} use X11 as their base graphical subsystem and thus always use a display server and a display client. macOS has built-in support for X11, but does not use it for normal applications. For Windows, commercial and free solutions implementing an X11 display client exist.

Until 2004, for most GNU/Linux distributions the default display server was {{w|XFree86}}. This project required a variation of the config file that Randall mentions. It was forked into Xorg due to disagreements over the development model.

Xorg is nowadays the default display server: X.Org Server (commonly abbreviated to Xorg Server, XServer or just X) refers to the X server release packages stewarded by the X.Org Foundation, which is hosted by {{w|freedesktop.org}}, and provides an interface to the standard X Window releases for the use of the free and open source software community.

Every aspect of XFree86 and Xorg can be modified in numerous ways, all the way down to tiny behaviors such as the default window size, window-border snapping, mouse button maps or how a touchpad is used. All of these settings can be found in the xorg.conf file, a massive file with hundreds upon thousands of individual settings that have accumulated over the lifetime of the Xorg project. The [http://www.x.org/archive/X11R6.8.1/doc/xorg.conf.5.html full documentation for xorg.conf] contains all the settings contained within the file. When a problem arises in the graphical portion of a desktop using the X server, the solution may be to edit the xorg.conf file. The soul-crushing prospect of having to open and look up the correct parameter out of thousands that is causing issues is enough to destroy a person's satisfaction with their life.

Editing xorg.conf (especially manually) is much less necessary than it used to be. In fact, some distributions do not even come with an xorg.conf file, because everything necessary can be auto-detected and/or configured elsewhere.

 

The title text references [http://press-pubs.uchicago.edu/founders/documents/v1ch2s23.html a letter] {{w|Thomas Jefferson}} wrote to {{w|James Madison}} on the popular basis of political authority. There are a few quotes that can be pulled to sum up his ideas.

 

::To keep our ideas clear when applying them to a multitude, let us suppose a whole generation of men to be born on the same day, to attain mature age on the same day, and to die on the same day, leaving a succeeding generation in the moment of attaining their mature age all together. Let the ripe age be supposed of 21. years, and their period of life 34. years more, that being the average term given by the bills of mortality to persons who have already attained 21. years of age.

 

In his day most people lived only to age 55, so he supposes that a person reaches maturity at 21, and will live until 55 and then die. For the purposes of the other arguments he makes in the letter, he also supposes that all the people of a generation are born on the same day, and that they will all die on the same day: the day they turn 56.

 

 

Since only one generation is alive in his example, his model allows for that generation to do as they please for their time on earth, elsewhere in the letter he describes that each generation should not be able to leave the next generation in a worse position, so the debts accrued by one generation must be paid off by that generation. This has built us up to the quote that everyone attaches onto.
