-.SH NAME
-XWin \- X Server for the Cygwin environment on Microsoft Windows
-
-
-.SH SYNOPSIS
-.B XWin
-[ options ] ...
-
-
-.SH DESCRIPTION
-\fIXWin\fP is an X Server for the X Window System on the Cygwin environment
-running on Microsoft Windows.
-
-
-.SH MODES
-\fIXWin\fP can operate in 3 different modes:
-.br
-* \fISingle Window\fP: This is the default mode.  Each X screen
-appears as a single \fIWindows\fP window and all X windows are contained
-within this window.
-(In X terminology, the \fIWindows\fP window contains the root window for
-the screen)
-.br
-* \fIMulti-Window\fP: In this mode \fIXWin\fP uses its own integrated
-window manager in order to handle the top-level X windows, in such a
-way that they appear as normal \fIWindows\fP windows.
-.br
-* \fIRootless\fP: In this mode the X server works in a window
-containing the whole screen but this root window (traditionally covered with an X hatch
-pattern) is hidden from view, so only top-level X windows are seen.
-
-.SH OPTIONS
-In addition to the normal server options described in the \fIXserver(1)\fP
-manual page, \fIXWin\fP accepts the following command line switches,
-\fIall\fP of which are optional:
-
-.SH OPTIONS CONTROLLING WINDOWING MODE
-Only one of these options may be specified.
-.TP 8
-.B (default)
-Windowed or rooted mode.
-Each X screen appears as a single \fIWindows\fP window and all X windows are
-contained within those windows.
-.TP 8
-.B \-multiwindow
-Each top-level X window appears in its own \fIWindows\fP window.
-Also start the integrated \fIWindows\fP-based window manager.
-.TP 8
-.B \-rootless
-Run the server in rootless mode.
-The X server works on a window covering the whole screen but the root window
-is hidden from view.
-.TP 8
-.B \-mwextwm
-Experimental.
-The mode combines \fB\-rootless\fP mode drawing with native \fIWindows\fP
-window frames managed by the experimental external window manager \fIxwinwm\fP.
-.PP
-\fBNOTE:\fP \fI-multiwindow\fP mode uses its own internal window manager.
-All other modes require an external window manager in order to move, resize, and perform other
-operations on the individual X windows.
-
-.SH OPTIONS FOR SPECIFYING X SCREENS
-An X display may be composed of multiple screens.
-The default behaviour is to create a single screen 0 that is roughly the
-size of useful area of the primary monitor (allowing for any window
-decorations and the task-bar).
-
-Screen specific parameters, such as \fB\-fullscreen\fP, can be applied as a
-default to all screens by placing those screen specific parameters
-before any \fB\-screen\fP parameter.  Screen specific parameters placed after
-the first \fB\-screen\fP parameter will apply only to the immediately
-preceeding \fB\-screen\fP parameter.
-.TP 8
-.B \-[no]multimonitors or \-[no]multiplemonitors
-Create a screen 0 that covers all monitors [the primary monitor] on a system with
-multiple monitors.
-This option is currently enabled by default in \fB\-multiwindow\fP mode.
-.TP 8
-.B "\-screen \fIscreen_number\fP [\fIW\fP \fIH\fP [\fIX\fP \fIY\fP] | [[\fIW\fPx\fIH\fP[+\fIX\fP+\fIY\fP]][@\fIM\fP]] ] "
-Create screen number
-.I screen_number
-and optionally specify it's
-.I height,
-.I width
-and
-.I initial position.
-Additionally a
-.I
-monitor number
-(which count from 1) can be specified to place the screen on,
-at which point, all coordinates become relative to that monitor.
-Screen numbers must be contiguous starting from zero and cannot be duplicated.
-
-Examples:
-
-.I "  -screen 0 @1 ; on 1st monitor using its full resolution (the default)"
-
-.I "  -screen 0 800x600+100+100@2 ; on 2nd monitor offset 100,100 size 800x600"
-
-.I "  -screen 0 1024x768@3        ; on 3rd monitor size 1024x768"
-
-.SH OPTIONS CONTROLLING THE APPEARANCE OF THE X SCREEN WINDOWS
-These parameters only apply to windowed mode screens i.e. not
-in \fB-multiwindow\fP or \fB-rootless\fP mode.
-.TP 8
-.B "\-fullscreen"
-The X server window takes the full screen, covering completely the

+.SH NAME

+XWin \- X Server for the Cygwin environment on Microsoft Windows

+

+

+.SH SYNOPSIS

+.B XWin

+[ options ] ...

+

+

+.SH DESCRIPTION

+\fIXWin\fP is an X Server for the X Window System on the Cygwin environment

+running on Microsoft Windows.

+

+

+.SH MODES

+\fIXWin\fP can operate in 3 different modes:

+.br

+* \fISingle Window\fP: This is the default mode.  Each X screen

+appears as a single \fIWindows\fP window and all X windows are contained

+within this window.

+(In X terminology, the \fIWindows\fP window contains the root window for

+the screen)

+.br

+* \fIMulti-Window\fP: In this mode \fIXWin\fP uses its own integrated

+window manager in order to handle the top-level X windows, in such a

+way that they appear as normal \fIWindows\fP windows.

+.br

+* \fIRootless\fP: In this mode the X server works in a window

+containing the whole screen but this root window (traditionally covered with an X hatch

+pattern) is hidden from view, so only top-level X windows are seen.

+

+.SH OPTIONS

+In addition to the normal server options described in the \fIXserver(1)\fP

+manual page, \fIXWin\fP accepts the following command line switches,

+\fIall\fP of which are optional:

+

+.SH OPTIONS CONTROLLING WINDOWING MODE

+Only one of these options may be specified.

+.TP 8

+.B (default)

+Windowed or rooted mode.

+Each X screen appears as a single \fIWindows\fP window and all X windows are

+contained within those windows.

+.TP 8

+.B \-multiwindow

+Each top-level X window appears in its own \fIWindows\fP window.

+Also start the integrated \fIWindows\fP-based window manager.

+.TP 8

+.B \-rootless

+Run the server in rootless mode.

+The X server works on a window covering the whole screen but the root window

+is hidden from view.

+.TP 8

+.B \-mwextwm

+Experimental.

+The mode combines \fB\-rootless\fP mode drawing with native \fIWindows\fP

+window frames managed by the experimental external window manager \fIxwinwm\fP.

+.PP

+\fBNOTE:\fP \fI-multiwindow\fP mode uses its own internal window manager.

+All other modes require an external window manager in order to move, resize, and perform other

+operations on the individual X windows.

+

+.SH OPTIONS FOR SPECIFYING X SCREENS

+An X display may be composed of multiple screens.

+The default behaviour is to create a single screen 0 that is roughly the

+size of useful area of the primary monitor (allowing for any window

+decorations and the task-bar).

+

+Screen specific parameters can be applied as a

+default to all screens by placing those screen specific parameters

+before any \fB\-screen\fP parameter.  Screen specific parameters placed after

+the first \fB\-screen\fP parameter will apply only to the immediately

+preceeding \fB\-screen\fP parameter.

+.TP 8

+.B \-[no]multimonitors or \-[no]multiplemonitors

+Create a screen 0 that covers all monitors [the primary monitor] on a system with

+multiple monitors.

+This option is currently enabled by default in \fB\-multiwindow\fP mode.

+.TP 8

+.B "\-screen \fIscreen_number\fP [\fIW\fP \fIH\fP [\fIX\fP \fIY\fP] | [[\fIW\fPx\fIH\fP[+\fIX\fP+\fIY\fP]][@\fIM\fP]] ] "

+Create screen number

+.I screen_number

+and optionally specify it's

+.I height,

+.I width

+and

+.I initial position.

+Additionally a

+.I

+monitor number

+(which count from 1) can be specified to place the screen on,

+at which point, all coordinates become relative to that monitor.

+Screen numbers must be contiguous starting from zero and cannot be duplicated.

+

+Examples:

+

+.I "  -screen 0 @1 ; on 1st monitor using its full resolution (the default)"

+

+.I "  -screen 0 800x600+100+100@2 ; on 2nd monitor offset 100,100 size 800x600"

+

+.I "  -screen 0 1024x768@3        ; on 3rd monitor size 1024x768"

+

+.SH OPTIONS CONTROLLING THE APPEARANCE OF THE X SCREEN WINDOWS

+These parameters only apply to windowed mode screens i.e. not

+in \fB-multiwindow\fP or \fB-rootless\fP mode.

+.TP 8

+.B "\-fullscreen"

+The X server window takes the full screen, covering completely the

+\fIWindows\fP desktop.

+Currently \fB\-fullscreen\fP may only be applied to one X screen.

+.TP 8

+.B \-nodecoration

+Do not give the Cygwin/X window a \fIWindows\fP window border, title bar,

+etc.

+This parameter is ignored when the \fB\-fullscreen\fP parameter is specified.

+.TP 8

+.B \-scrollbars

+Alternative name for \fB\-resize=scrollbars\fP.

+

+.SH OPTIONS CONTROLLING RESIZE BEHAVIOUR

+.TP 8

+.B \-resize[=none|scrollbars|randr]

+Select the resize mode of an X screen.

+

+.RS

+.IP \fB\-resize=none\fP 8

+(default). The screen is not resizable.

+

+In windowed mode, if the window has decorations, a fixed frame is used.

+

+.IP \fB\-resize=scrollbars\fP 8

+The screen window is resizeable, but the screen is not resizable.

+

+In windowed mode, if the window has decorations, a resizing frame is used.

+Scrollbars are drawn when needed to allow the entire X screen

+to viewed by adjusting them.

+

+This also permits screens bigger than the \fIWindows\fP virtual desktop to be used.

+

+This parameter is ignored in \fB-multiwindow\fP or \fB-rootless\fP mode.

+Alternative name is \fB\-scrollbars\fP.

+

+.IP \fB\-resize=randr\fP 8

+The screen is resizable and the screen window is resizeable.

+

+In windowed mode, if the window has decorations, a resizing frame is used.

+

+Resizing the  \fIWindows\fP window will use the RANDR extension to change

+the size of the X screen.  Likewise, changing the size of

+the X screen using the RANDR extension will cause the size

+of the \fIWindows\fP window containing the X screen to be changed.

+

+In \fB-multiwindow\fP or \fB-rootless\fP mode, if the X screen is

+of the same dimensions as a Windows monitor or the virtual desktop,

+the X server will respond to the WM_DISPLAYCHANGED sent when those

+dimensions change by resizing the X screen.  Changing the size

+of the X screen using the RANDR extension is not permitted.

+

+The maximum dimensions of the screen are the dimensions of the \fIWindows\fP virtual desktop.

+

+.IP \fB\--resize\fP 8

+on its own is equivalent to \fB\--resize=randr\fP

+The format of the \fI.XWinrc\fP file is given in the man page XWinrc(5).

+

+.SH EXAMPLES

+Need some examples

+

+

+.SH "SEE ALSO"

+X(__miscmansuffix__), Xserver(1), xdm(1), xinit(1), XWinrc(__filemansuffix__), setxkbmap(1)

+

+

+.SH BUGS

+.I XWin

+and this man page still have many limitations.

+

+The \fIXWin\fP software is continuously developing; it is therefore possible that

+this man page is not up to date.  It is always prudent to

+look also at the output of \fIXWin -help\fP in order to

+check the options that are operative.
