Xming

(2020-4-26) やはり T61 の画面を大画面で扱いたい。が、RDP は懲りたので xming を再開したく、DISPLAY の処を再勉強する。

DISPLAY - なんなんなん行く？
Xming + Teraterm で画面転送

古い PyTTY はエラー

　インストールしていた Xming が古いせいか、起動時に PyTTY がエラーを起こす。

　これが誰かを調べると…

Xming をインストールした場所の plink.exe を使おうとしている。
ので、見えなく（削除 or リネーム）する。

すると XLaunch.exe が plink.exe の場所を尋ねるようになるので、そこで新しい物を指定する。某は gow の物を指定した。

さほど新しくもない2011年物だが、これで通信は成功する。

 C:\Program Files\Gow\bin のディレクトリ
2011/12/11  01:35           303,104 plink.exe

DISPLAY 変数は何処で宣言されている？

/etc/X11/Xsession: # is available and $DISPLAY is set
/etc/X11/Xsession: if [ -n "$DISPLAY" ] && which xmessage > /dev/null 2>&1; then
/etc/X11/Xsession: # xmessage if it is available and $DISPLAY is set
/etc/X11/Xsession: if [ -n "$DISPLAY" ] && which xmessage > /dev/null 2>&1; then
/etc/X11/Xsession.d/20dbus_xdg-runtime: DBUS_SESSION_BUS_ADDRESS DISPLAY XAUTHORITY
/etc/rc6.d/K01sddm:

grep: /etc/initramfs-tools/conf.d/calamares-safe-initramfs.conf: Permission denied
/etc/security/pam_env.conf:# Set the DISPLAY variable if it seems reasonable

$ less -NS /etc/security/pam_env.conf

-clipboard
	Enables the integration between the Xming clipboard and
	Windows clipboard.
-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.
-depth bits_per_pixel
	Specify an optional bitdepth to use in fullscreen mode
	with a DirectDraw engine.
-emulate3buttons [timeout]
	Emulate a 3 button mouse with an optional timeout in
	milliseconds.  The default timeout is 50 milliseconds.
-engine engine_type_id
	Override the server's automatically selected engine type:
		1 - Shadow GDI
		2 - Shadow DirectDraw
		4 - Shadow DirectDraw4 Non-Locking
	Do not use this parameter unless instructed to do so.
-fullscreen
	Run the server in fullscreen mode with -depth and -refresh
	set as required.
-ignoreinput
	Ignore keyboard and mouse input.  This is usually only used for
	testing and debugging purposes.
-internalwm
	EXPERIMENTAL: Run the internal window manager.
-[no]keyhook
	Grab special windows key combinations like Alt-Tab or the Menu
	key.  These keys are discarded by default.
-lesspointer
	Hide the windows mouse pointer when it is over an inactive
	Xming window.  This prevents ghost cursors appearing where
	the Windows cursor is drawn over the X cursor.
-logfile filename
	Write logmessages to  instead of Xming.n.log,
	where n is the display-number of the X Server.
-logverbose verbosity
	Set the verbosity of logmessages. [NOTE: Only a few messages
	respect the settings, so not much use 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.
-mwextwm
	EXPERIMENTAL: Run the server in multiwindow external
	window manager mode. Use with xwinwm.
-nodecoration
	Do not draw a window border, title bar, etc.  Windowed
	mode only i.e. ignored when -fullscreen specified.
-noicons
	Disable the conversion of X icons in multiwindow mode.
	Use to prevent an infrequent crash in miGetImage().
	This is a work-around that most people won't need.
-nounicodeclipboard
	Disable Unicode in the clipboard.
-refresh rate_in_Hz
	Specify an optional refresh rate to use in fullscreen mode
	with a DirectDraw engine.
-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)
-scrollbars
	In windowed mode, allow screens bigger than the Windows desktop.
	Moreover, if the window has decorations, one can now resize
	it.  Do not use in conjunction with -multiwindow or with -rootless.
-silent-dup-error
	If another instance of Xming is found running, exit silently
	and don't display the 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
	-trayicon for those screens.
-[no]unixkill
	Ctrl-Alt-Backspace exits the X Server. The Ctrl-Alt-Backspace
	key combo is disabled by default.
-version
	Write version and help text to the console (unless built
	console-less) and to the log file.
-[no]winkill
	Alt-F4 exits the X Server.  The Alt-F4 key combo is enabled
	by default.
-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
