NAME

Xibm - X Window System (version 11) Server for IBM equipment

SYNOPSIS

Xibm [options]

DESCRIPTION

X is a network-transparent windowing system developed at MIT which runs under several operating systems and environments.  Xibm is an X server based on the MIT sample server described in xwindows(1). 

A script interface for Xibm, which starts the server, provides a window manager, and opens some windows, is provided by xwindows(1). 

Only options and functions specific to IBM X servers are described here.  For complete information on the X server, see xwindows(1). 

Xibm is a multi-screen server.  One server can manipulate one or several screens simultaneously.  Alternatively, you can invoke a different instantiation of the server for each screen (thereby rendering “screen” and “display” equivalent; remember that in X parlance, “display” means server and “screen” means physical device). 

A multi-screen server will move the cursor from screen to screen by moving off the edge of one screen onto the edge of the logical next screen.  Logical ordering of screens is controllable with command line options (see below). 

OPTIONS

Options understood by X and documented in xwindows(1) are not described here.  Options specific to Xibm are:

-pckeys
Reverses the interpretation of the CAPS-LOCK and CTRL keys, to emulate the key positions on a PC keyboard.

-rtkeys
Default.  Interprets CAPS-LOCK and CTRL as defined on the IBM RT PC keyboard.

-wrapx
Allows the cursor to wrap from the extreme rightmost position of the rightmost screen to the leftmost position of the leftmost screen.  Without this option, the cursor is blocked at the extreme left of the leftmost screen, and at the extreme right of the rightmost screen.

-wrapy
Allows the cursor to wrap from the top position of the highest screen to the bottom position of the lowest screen.  Without this option, the cursor is blocked at the top of the top screen, and at the bottom of the bottom screen.

-wrap Specifies both -wrapx and -wrapy. 

-8514 Instructs the server to use the IBM 8514/A polychrome adapter and attached display, if installed.  For use on a machine with an 8514/A installed, this is the default. 

-vga Instructs the server to use the PS/2 planar Video Graphics Array polychrome display controller with its attached display, if installed. 

-mpel Instructs the server to use the IBM Megapel color adapter and attached 5081 display, if installed.  For IBM RT PC machines with this device installed, this is the default. 

-ega Instructs the server to use the IBM 5154 and Enhanced Color Display, if installed. 

-apa16
Instructs the server to use the IBM 6155 Extended Monochrome Graphics Display, if installed.

-aed Instructs the server to use the IBM Academic Information Systems experimental display, if installed.  This display is not generally available. 

r Instructs the server to activate auto-repeat keys on the keyboard. 

-r Instructs the server to de-activate auto-repeat keys.  This is the default. 

ORDERING SCREENS

If the Xibm command is entered without requesting a particular screen, the first screen found from the following list will be used:

8514
vga
mpel
ega
apa16
aed

If screens are specified, then the screens will be logically ordered, from left to right, in the order they are specified on the command line.  For example:
Xibm -apa16 -mpel r

will start Xibm on two screens with :0.0 on the 6155 in the logical left position, and :0.1 on the 5081 in the logical right position.  The cursor will hop from the right edge of the 6155 to the left edge of the 5081, and vice versa.  For explanation of the terminology “:X.Y”, see xwindows(1). 

SCREEN CHARACTERISTICS

The 8514 is 1024x768 pixels, 256 or 16 displayable colors (depending on installed memory option) from a palette of 265K possible colors.  With a greyscale display attached, only 64 distinct shades of grey can be displayed. 15-inch color (8514) or 16-inch greyscale (8604) displays are supported. 

The VGA is 640x480 pixels, with 16 displayable colors or greys from a palette of 256K possible colors or 64 possible greys.  13-inch color (8513) or greyscale (8503) are supported. 

The 5081 is 1024x1024 pixels with 256 displayable colors from a palette of 4096 possible colors.  The 5081 is supported in both 16- and 19-inch models. 

The 5154 is 640x480 pixels, with 16 colors, from a palette of 64 possible colors. 

The 6155 is 1024x768 pixels, monochrome. 

The IBM Academic Information Systems experimental display is 1024x800, monochrome.

BUGS

Moving windows from screen to screen is not supported. 

Starting two servers on the same screen can lead to interesting and unpredictable results.
