Name
Xws - X server for RISC machines
Syntax
Xws [ options ]
Description
The command starts the X server. The command supports the following hardware configurations:
DECstation/DECsystem 3100 Single Screen Color Workstations
DECstation/DECsystem 3100 Single Screen Monochrome Workstations
DECstation/DECsystem 5000 Single Screen Color Workstations
DECstation/DECsystem 5000 Single Screen Monochrome Workstations
DECstation/DECsystem 5000 Multiscreen Color Workstations
DECstation/DECsystem 5000 Multiscreen Monochrome Workstations
The command that executes the server is specified together with its command line options in the file and, therefore, is automatically run
when your system is started in multiuser mode. Optionally, you can create an file containing device-dependent command line options (sepa-
rated by spaces) and use it to start the server. Command line options specified in the file override those specified in the file.
Start the server in bug compatibility mode (with the bc option) to remain bug-for-bug compatible with previous releases of the server.
Options
The following options are device independent. These options are available on all workstation hardware platforms running X11 Release 4
servers.
-a num Sets the mouse acceleration value to the specified number of pixels. The default is 4.
-auth string Selects a file containing authorization records. Hosts listed in the file are allowed to access to the server's dis-
play. By default, no authorization file is used.
bc Enables bug compatibility with previous releases.
-bs Disables Backing Store. Backing Store is disabled if you specify the -bs option on the command line.
-c Turns off key clicking.
c num Sets the key click volume to the specified number (0-100). The default is 20.
-co string Selects a color database. The default is
-f num Sets the bell volume to the specified number (0-100). The default is 50.
-fc string Sets the default cursor font. The default is
-fd num Sets the font size in dots per inch. Acceptable values are 75 and 100.
-fn string Sets the default text font. The default is
-fp string Sets the default font directory path. The default font directory paths are:
+fp path[,path...] Prepends the specified font paths to the default path.
fp+ path[,path...] Appends the specified font paths to the default path.
-help Displays the command usage message.
-I Directs the server to ignore all remaining command line arguments.
-ld num Limits data space to num Kbytes.
-ls num Limits stack space to num Kbytes.
-logo Enables the X logo screen saver.
logo Disables the X logo screen saver.
-p seconds Determines how long to wait before changing the background pattern of the screen saver. The default is 10 seconds.
-r Turns off automatic repetition of keyboard key characters.
r Turns on automatic repetition of keyboard key characters. The default is on.
-s seconds Sets the screen-saver timeout value to the specified number of seconds. The default is 10.
-su Disables Save-Unders.
-t num Sets the mouse threshold in pixels. The mouse will accelerate only if the threshold is exceeded. The default thresh-
old is 4.
-to seconds Specifies the number of seconds for the server to wait before declaring a session connection timed out.
ttyxx Specifies the terminal on which the server is to start. The Wttyxx is a valid command line option, but it is ignored
by the WXws server.
v Specifies that a blank screen is used for the screen saver. This is the default screen saver.
-v Specifies that a pattern (noblank) screen is used for the screen saver.
-wm Enables the use of Backing Store with WhenMapped calls.
-x string Loads the file string containing an X extension.
:num On a multihead system, specifies the head on which the server is run (0 or 1). The default is 0.
-broadcast Enables X Display Manager Control Protocol (XDMCP) and sends broadcast query packets over the network.
-displayID display-id
For XDMCP, identifies manufacturer's display ID for display
-indirect hostname Enables XDMCP and sends indirect query packets to the specified host.
-once Terminates the server after one session.
-port num Specifies the UDP port number that will receive messages.
-query hostname Enables XDMCP and sends query packets to the specified host.
-XDMCP_class display-class
Specifies an additional display qualifier used in resource management by XDMCP.
The following are device-dependent, vendor-specific options. When the server is run on multiscreen capable platforms, selected device-
dependent options take an optional screen-specification argument. Omitting the screen-specification argument defines the parameter for all
available screens.
-btn num Specifies the number of buttons on the pointer device. The default is three for a mouse device and four for a tablet
device.
-bp[screen] color Sets the color of black pixels for the screen. The color argument can be a named color from the database or a number
sign (#) followed by a hexidecimal number.
-class[screen] visual class
Sets the visual class for the root window of the screen. Possible values are and
-dpi[screen] num Sets the dots per inch for the x and y coordinates.
-dpix[screen] num Sets the dots per inch for the x coordinates.
-dpiy[screen] num Sets the dots per inch for the y coordinates.
-edge_bottomscr1 scr2
Attaches the bottom edge of the screen specified by scr1 to the screen specified by scr2.
-edge_leftscr1 scr2 Attaches the left edge of the screen specified by scr1 to the screen specified by scr2.
-edge_rightscr1 scr2
Attaches the right edge of the screen specified by scr1 to the screen specified by scr2.
-edge_topscr1 scr2 Attaches the top edge of the screen specified by scr1 to the screen specified by scr2.
-wp[screen] color Sets the color of white pixels for the screen. The syntax for color is the same as for the argument to the -bp option.
-tb n Opens for graphics tablet communications. The two free serial ports on the DECstation correspond to and A graphics
tablet must be connected through one of these two ports.
-pcm n Opens for Protocol Control Module (PCM) communications. The two free serial ports on the DECstation correspond to and
Dial boxes and button boxes must be connected through these two ports.
Restrictions
If options not listed in this reference page are used, the server may fail. Using invalid options for the X server in the file may cause
the workstation to behave as if the X server is hung.
Multiscreen configurations can contain either two- or three-color frame buffer display devices or monochrome frame buffer display devices.
Color and monochrome frame buffer display devices cannot be installed in the same workstation. Only homogeneous installations are allowed.
To connect two screens, two command line options must be issued. Attaching two screens using only one argument produces a one-way mouse-
travel path. You can create a wrap-around mouse path by attaching noncontiguous screen edges. The arguments are disabled on single screen
systems.
Nonsensical screen connections are not allowed; the top edge of a particular screen must be connected with the bottom edge of another
screen, and the right edge of a particular screen must be connected with the left edge of another screen. Left and right edges cannot be
connected to top or bottom edges.
Examples
The following example specifies that screen has a resolution of 100x100 dots per inch and screen has a resolution of 75x70 dots per inch:
Xws -dpi0 100 -dpix1 75 -dpiy1 70
If no screen is specified, the value specified is used for all screens. If the screen resolution is not specified using command line
options, a default value based on pixel dimensions and screen size is calculated for each screen.
The following example specifies that black pixels on screen have the hexadecimal value 3a009e005c0 prefixed with a number sign (#) and
white pixels on screen are color "wheat" from the X rgb color database.
Xws -bp1 #3a009e005c0 -wp1 wheat
For monochrome display devices, values of 0 and 1 are the only valid pixel colors.
To specify the default visual class of a root window on a particular screen, append the screen number (0, 1, or 2) to the command line
option. Possible visual classes are: StaticGray, StaticColor, PseudoColor, GrayScale, and TrueColor. The following example specifies that
the screen root window is a TrueColor visual, and the screen root window is a PseudoColor visual.
Xws -class0 TrueColor -class1 PseudoColor
The following example attaches screen above screen and screen to the right of screen (an L-shaped configuration):
Xws -edge_top0 1 -edge_bottom1 0 -edge_right0 2 -edge_left2 0
The following example is identical to the default state (a horizontal line) with the addition of a wraparound from screen to screen
Xws -edge_left0 2 -edge_right0 1 -edge_left1 0 -edge_right1 2
-edge_left2 1 -edge_right2 0
