Name

Xcomp − X Window System Version 10 compatibility server

Syntax

Xcomp number [ options ]

Arguments

numberSpecifies the number of the display that is to connect to the X10 compatibility server.  The display number must be one that has not already been connected to an X10 server. 

Description

The Xcomp command is an X10 compatibility server that allows you to run X10 client applications in a single X11 window. 

The Xcomp command uses the DISPLAY environment variable to determine the display on which its window is displayed. 

The X10 clients displayed in the window in which Xcomp is running use a DISPLAY environment variable where the display number corresponds to the specified Xcomp number argument. 

An X11 window manager can not run in the window in which Xcomp is running. 

The X10 fonts are available converted to X11 format.  The dxfconv application allows you to convert fonts from X10 to X11. For information about compiling a font file so it can be used by the DECwindows display server, see dxfc(.).

Options

−0 colorSets color map entry 0 (BlackPixel) to the specified color.  The default is #000080 (light blue). 

−1 colorSets color map entry 1 (WhitePixel) to the specified color.  The default is #ffffff. 

−D fileSets the RGB database to the specified file.  The default is /usr/lib/X11/rgb. 

−display dispnameSpecifies the display screen on which Xcomp displays its window.  If the display option is not specified, Xcomp uses the display screen specified by your DISPLAY environment variable.  The display option has the format hostname:number.  Using two colons (::) instead of one (:) indicates that DECnet is to be used for transport.  The default is :0.  For more information, see X(.).

−geometrySpecifies the width, length, and location of the Xcomp window.  If the geometry option is not specified, Xcomp uses default values.  The geometry option has the format [width][xlength][x][y].  For more information about the screen coordinate system, see X(.).

−mSpecifies Xcomp use a monochrome display at startup.  The only colors available are black and white. 

−p numSets the screen saver pattern duration in seconds.  The default is 10 seconds. 

−s numSets the screen-saver timeout value to the specified number of minutes.  The default is 10. 

−t numSets the mouse threshold beyond which the mouse acceleration applies to the specified number of pixels.  The default is 4. 

Restrictions

The window in which Xcomp is running has fewer color planes than the X11 server it is running under. 

If the uwm window manager is running on both the X11 server and the X10 server in the Xcomp window, there may be conflict with key and mouse button bindings.
