VCXSrv.0

# It looks like -multiwindow mode triggers the static color visual in both the internal x2go xserver and the external vcxsrv
# But it also looks like -multiwindow mode is how x2go client allows resizing of the remote desktop
# ...so I'm looking for a way to allow resizing of remote desktop w/out triggering static color visual.

VcXsrv Device Dependent Usage:

-[no]clipboard
	Enable [disable] the clipboard integration. Default is enabled.
-[no]clipboardprimary
	[Do not] map the PRIMARY selection to the windows clipboard.
	The CLIPBOARD selection is always mapped if -clipboard is enabled.
	Default is mapped.
-clipupdates num_boxes
	Use a clipping region to constrain shadow update blits to
	the updated region when num_boxes, or more, are in the
	updated region.
-depth bits_per_pixel
	Specify an optional bitdepth to use in fullscreen mode
	with a DirectDraw engine.
-[no]emulate3buttons [timeout]
	Emulate 3 button mouse with an optional timeout in
	milliseconds.
-engine engine_type_id
	Override the server's automatically selected engine type:
		1 - Shadow GDI
		2 - Shadow DirectDraw

	Ignore keyboard and mouse input.
-[no]keyhook
	Grab special Windows keypresses like Alt-Tab or the Menu key.
-lesspointer
	Hide the windows mouse pointer when it is over any
	VcXsrv window.  This prevents ghost cursors appearing when
	the Windows cursor is drawn on top of the X cursor
-logfile filename
	Write log messages to <filename>.
-logverbose verbosity
	Set the verbosity of log messages. [NOTE: Only a few messages
	respect the settings yet]
		0 - only print fatal error.
		1 - print additional configuration information.
		2 - print additional runtime information [default].

-refresh rate_in_Hz
	Specify an optional refresh rate to use in fullscreen mode
	with a DirectDraw engine.
-resize=none|scrollbars|randr	In windowed mode, [don't] allow resizing of the window. 'scrollbars'
	mode gives the window scrollbars as needed, 'randr' mode uses the RANR
	extension to resize the X screen.  'randr' is the default.
-rootless
	Run the server in rootless mode.
-screen scr_num [width height [x y] | [[WxH[+X+Y]][@m]] ]
	Enable screen scr_num and optionally specify a width and
	height and initial position for that screen. Additionally
	a monitor number can be specified to start the server on,
	at which point, all coordinates become relative to that
	monitor. Examples:
	 -screen 0 800x600+100+100@2 ; 2nd monitor offset 100,100 size 800x600
	 -screen 0 1024x768@3        ; 3rd monitor size 1024x768
	 -screen 0 @1 ; on 1st monitor using its full resolution (the default)
-silent-dup-error
	If another instance of VcXsrv with the same display number is running
	exit silently and don't display any error message.
-swcursor
	Disable the usage of the Windows cursor and use the X11 software
	cursor instead.
-[no]trayicon
	Do not create a tray icon.  Default is to create one
	icon per screen.  You can globally disable tray icons with
	-notrayicon, then enable it for specific screens with

	For example: -xkblayout de
-xkbmodel XKBModel
	Equivalent to XKBModel in XF86Config files.
-xkboptions XKBOptions
	Equivalent to XKBOptions in XF86Config files.
-xkbrules XKBRules
	Equivalent to XKBRules in XF86Config files.
-xkbvariant XKBVariant
	Equivalent to XKBVariant in XF86Config files.
	For example: -xkbvariant nodeadkeys
(EE) Server terminated successfully (0). Closing log file.

Thanks.

How did you find this? I haven't been able to find it, and running vcxsrv.exe -help doesn't produce this; neither does running it without commands. Documentation is quite literally non-existent on the project's SourceForge, and all I can find are these Gist's here and there by different people like yourself. Any ideas where I might be able to get an updated list for v1.20.6.0 (the latest version)?

% strings -n 8 $(which vcxsrv.exe)

Thanks. Some of the options have change in my version which results in a crash if you use the wrong ones.

-[no]clipboard Enable [disable] the clipboard integration. Default is enabled. -noprimary Do not map the PRIMARY selection to the windows clipboard. The CLIPBOARD selection is always mapped if -clipboard is enabled. Default is mapped. -clipupdates num_boxes Use a clipping region to constrain shadow update blits to the updated region when num_boxes, or more, are in the updated region. Diminished effect on current Windows versions because they already group GDI operations together in a batch, which has a similar effect. -[no]compositewm Enable [Disable] Composite extension. Default is enabled. Used in -multiwindow mode. Use Composite extension redirection to maintain a bitmap image of each top-level X window, so window contents which are occluded show correctly in Taskbar and Task Switcher previews. -[no]compositealpha X windows with per-pixel alpha are composited into the Windows desktop. -[no]compositewm Use the Composite extension to keep a bitmap image of each top-level X window, so window contents which are occluded show correctly in task bar and task switcher previews. -depth bits_per_pixel Specify an optional bitdepth to use in fullscreen mode with a DirectDraw engine. -[no]emulate3buttons [timeout] Emulate 3 button mouse with an optional timeout in milliseconds. -engine engine_type_id Override the server's automatically selected engine type: 1 - Shadow GDI 4 - Shadow DirectDraw4 Non-Locking -fullscreen Run the server in fullscreen mode. -[no]hostintitle In multiwindow mode, add remote host names to window titles. -icon icon_specifier Set screen window icon in windowed mode. -ignoreinput Ignore keyboard and mouse input. -[no]keyhook Grab special Windows keypresses like Alt-Tab or the Menu key. -lesspointer Hide the windows mouse pointer when it is over any VcXsrv window. This prevents ghost cursors appearing when the Windows cursor is drawn on top of the X cursor -logfile filename Write log messages to <filename>. -logverbose verbosity Set the verbosity of log messages. [NOTE: Only a few messages respect the settings yet] 0 - only print fatal error. 1 - print additional configuration information. 2 - print additional runtime information [default]. 3 - print debugging and tracing information. -[no]multimonitors or -[no]multiplemonitors Use the entire virtual screen if multiple monitors are present. -multiwindow Run the server in multiwindow mode. Not to be used together with -rootless or -fullscreen. -nodecoration Do not draw a window border, title bar, etc. Windowed mode only i.e. ignored when -fullscreen specified. -nounicodeclipboard Disable Unicode in the clipboard. -[no]primary When clipboard integration is enabled, map the X11 PRIMARY selection to the Windows clipboard. Default is enabled. -refresh rate_in_Hz Specify an optional refresh rate to use in fullscreen mode with a DirectDraw engine. -resize=none|scrollbars|randr In windowed mode, [don't] allow resizing of the window. 'scrollbars' mode gives the window scrollbars as needed, 'randr' mode uses the RANR extension to resize the X screen. 'randr' is the default. -rootless Use a transparent root window with an external window manager (such as openbox). Not to be used with -multiwindow or with -fullscreen. -screen scr_num [width height [x y] | [[WxH[+X+Y]][@m]] ] Enable screen scr_num and optionally specify a width and height and initial position for that screen. Additionally a monitor number can be specified to start the server on, at which point, all coordinates become relative to that monitor. Examples: -screen 0 800x600+100+100@2 ; 2nd monitor offset 100,100 size 800x600 -screen 0 1024x768@3 ; 3rd monitor size 1024x768 -screen 0 @1 ; on 1st monitor using its full resolution (the default) -swcursor Disable the usage of the Windows cursor and use the X11 software cursor instead. -[no]trayicon Do not create a notification area icon. Default is to create one icon per screen. You can globally disable notification area icons with -notrayicon, then enable them for specific screens with -trayicon for those screens. -[no]unixkill Ctrl-Alt-Backspace exits the X Server. The Ctrl-Alt-Backspace key combo is disabled by default. -[no]wgl Enable the GLX extension to use the native Windows WGL interface for hardware-accelerated OpenGL -swrastwgl Enable the GLX extension to use the native Windows WGL interface based on the swrast interface for accelerated OpenGL -[no]winkill Alt+F4 exits the X Server. -xkblayout XKBLayout Set the layout to use for XKB. This defaults to a layout matching your current layout from Windows or us (i.e. USA) if no matching layout was found. For example: -xkblayout de -xkbmodel XKBModel Set the model to use for XKB. This defaults to pc105. -xkboptions XKBOptions Set the options to use for XKB. This defaults to not set. -xkbrules XKBRules Set the rules to use for XKB. This defaults to xorg. -xkbvariant XKBVariant Set the variant to use for XKB. This defaults to not set. For example: -xkbvariant nodeadkeys

I realize that this was posted some time ago. However, I was having issues using -screen 0 @2 to try and display the X11 screen on my second monitor. However, when I do that; the full screen still appears to take over my primary screen.

This produced the following error in log file (with the attached popup screen):
