NAME

XmacII - Macintosh II server for X Version 11

SYNOPSIS

XmacII [ option ] ...

DESCRIPTION

XmacII is the server for Version 11 of the X window system on Macintosh II hardware running A/UX. It will normally be started by the shell script X11.

CONFIGURATIONS

XmacII operates under A/UX Release 1.0 and later. Under A/UX Release 1.0, the server supports a single monochrome display. Color and multiple screens are supported under A/UX Release 1.1 and later.

OPTIONS

The following options can be given on the command line to the X server.

-screen number -depth number: arranges that the given screen will operate at the given depth. Screens are numbered from 0 and correspond to the relative position of video cards in the Macintosh II slots. Supported depths are 1 (monochrome at 1 bit per pixel, the default value), and 8 (color at 8 bits per pixel, indexing a colormap with 256 entries). Multiple screens and color support require A/UX Release 1.1 or later.
-a number: sets pointer acceleration (i.e. the ratio of how much is reported to how much the user actually moved the pointer).
-logo: turns on the X Window System logo display in the screen-saver. There is currently no way to change this from a client.
nologo: turns off the X Window System logo display in the screen-saver. There is currently no way to change this from a client.
-p minutes: sets screen-saver pattern cycle time in minutes.
-r: turns off auto-repeat.
r: turns on auto-repeat.
-s minutes: sets screen-saver timeout time in minutes.
-t numbers: sets pointer acceleration threshold in pixels (i.e. after how many pixels pointer acceleration should take effect).
-to seconds: sets default screensaver timeout in seconds.
-co filename: sets name of RGB color database
-help: prints a usage message
-fp fontPath: sets the search path for fonts
-fc cursorFont: sets default cursor font
-fn font: sets the default font

BUTTON MAPPINGS

Many X clients assume the mouse has three buttons. The A/UX X server simulates the middle and right mouse buttons with keystrokes -- the left-arrow key generates middle button events, and the right-arrow key generates right button events -- the real mouse button generates left button events. The open-apple or cloverleaf key is the "Meta" modifier, Meta can also be obtained by pressing the up-arrow key. The down-arrow key duplicates the Control key. Meta, Control, and Shift are often used in combination with other keystrokes or mouse clicks. For example, the terminal emulator xterm pops up menus in response to control-left and control-middle. The original function of the arrow keys may be obtained by holding down the Option key while pressing one of the arrow keys.

SECURITY

X uses an access control list for deciding whether or not to accept a connection from a given client. This list initially consists of the machine on which the server is running, and any hosts listed in the file /etc/X0.hosts This file should contain one line per host name, with no white space.

The user can manipulate a dynamic form of this list in the server using the xhost(1) program from the same machine as the server.

Unlike some window systems, X does not have any notion of window operation permissions or place any restrictions on what a client can do; if a program can connect to a display, it has full run of the screen. There is support for using authentication services on connection startup beyond the simple host name check, but it is not used in the standard distribution.

FONTS

Fonts are stored in individual files in the directory(ies) named by the font search path. These files may be created by the fc utility. The name of the file must correspond to the name of the font in lowercase with the suffix ".snf" appended. Font files may be stored in compress(1) format, in which case an additional suffix (usually ".Z", defined when the server is built) must be appended to the usual filename.

BUGS

In the unlikely event the server crashes, it may leave the keyboard in a non-useful state. The X11 script executes the Xrepair command in an attempt to repair the damage.
