• XDMCP arrived with the introduction of X11R4 ( December 1989 ).
• Versions supporting X11R4 and X11R5 were developed for Apple by a small team of engineers at AGE Logic, Inc ., a San Diego, California company.
• IRIX 4.0, released in 1991, replaced 4Sight with the X Window System ( X11R4 ), the 4Dwm window manager providing a similar look and feel to 4Sight.
• Only "'uwm "'was ported, so it became the only window manager for X Window System until X11R4 release, where it was replaced by twm . "'uwm "'has never been updated since.
• Various display managers continue in routine use to provide a graphical login prompt on standalone computer workstations running X . X11R4 introduced the "'X Display Manager Control Protocol "'( "'XDMCP "') in December 1989 to fix problems in the X11R3 implementation.
• "' MacX "'is a display server implementation supporting the X11 display server protocol that ran on System 7, Mac OS 8, and Mac OS 9 . It also ran under A / UX . Prior to X11R4 and the introduction of the PowerPC-based Power Macintosh, this server was developed internally by Apple Inc . for the Motorola 68000 based Macintoshes.
• An X terminal runs an X server . ( In X, the usage of " client " and " server " is from the viewpoint of the programs : the X server supplies a screen, keyboard, mouse and touchscreen to client applications . ) This connects to an X display manager ( introduced in X11R3 ) running on a central machine, using XDMCP ( X Display Manager Control Protocol, introduced in X11R4 ).
