x2x(1)x2x(1)NAMEx2x - X to X connection
SYNTAXx2x <[-to <DISPLAY>] | [-from <DISPLAY>]> [options...]
DESCRIPTIONx2x allows the keyboard and mouse on one ("from") X display to be used
to control another ("to") X display. Since x2x uses the XTEST exten‐
sion, the "to" X display must support XTEST.
In the default interface, x2x puts a window on the "from" display.
This window is labeled with the name of the "to" display. Keystrokes
typed into this window go to the window on the "to" display that has
the input focus. Clicking on the x2x window causes the mouse on the
"from" display to control the cursor on the "to" display. Performing a
subsequent multiple button click on the "to" display returns control to
the "from" display.
If the -east or -west options are specified on the command line, x2x
starts up with a different interface. When the mouse moves to the
(east or west) side of the default screen on the "from" display, the
cursor slides over to the "to" display. When the mouse returns to to
side of the "to" display that it entered, it slides back onto the
"from" display.
Unless the -nosel option is specified, x2x relays X selections from one
display to the other.
Here are a few hints for eXcursion users (based on Intel version
2.1.309). First, use the -big option. Second, in the control panel,
under mouse, check the box that enables "Automatically Capture Text on
Button Up." X selections will then automatically move into the Windows
clipboard. As is the case with all X applications running on 2.1.309
(including x2x), you will need to do an extra mouse click after per‐
forming the X selection for this operation to work. x2x is known to
work poorly with eXcursion running on Windows 95, probably due to the
Windows 95 task scheduler. x2x does work well with eXcursion running
on Windows NT.
The hints for eXcursion are also valid for Exceed, with the exception
that X selections work better, as long as you are using x2x version
1.25 or later.
OPTIONS
Either the -to option or the -from option (or both) must be specified.
-to display
Indicates the ("to") display that is remotely controlled by the
"from" display. Default is equivalent to the default display.
-from display
Indicates the ("from") display that remotely controls the "to"
display. Default is equivalent to the default display.
-east
Slide off the east side of the "to" display onto the "from" dis‐
play.
-west
Slide off the west side of the "to" display onto the "from" dis‐
play.
-font fontname
The font used in the x2x window. (Overridden by -east or -west.)
-geometry specification
The X geometry specification for the x2x window. (Overridden by
-east or -west.)
-wait
Tells x2x to poll the "to" and "from" displays at startup until
they are ready. Useful for login scripts.
-big
Workaround for a bug in the cursor grab implementations of at
least one X server. Put a big window over the "to" display in
order to force the X server to track the cursor.
-buttonblock
If this option is enabled with -east or -west, the cursor will
not slide back onto the "from" display when one or more mouse
buttons are pressed.
-nomouse
Don't capture the mouse. (Overridden by -east or -west.)
-nopointermap
Since x2x uses XTEST, which sends input at a lower level than
the pointer button mapping, x2x needs to understand the "to"
display's button mapping and do appropriate conversion. Use
this option to turn off the pointer button conversion.
-nosel
Don't relay the X selection between displays.
-noautoup
Normally, the autoup feature in x2x automatically lifts up all
keys and mouse buttons when it removes the cursor from the
"from" display. Note: the autoup feature changes the state of
lock functions like Caps Lock. The state of the lock function
may not correspond to the state of the keyboard LEDs! To dis‐
able this feature, use the -noautoup command line option.
-resurface
Ugly hack to work-around window manager ugliness. The -east and
-west modes actually put a small window on the side of the
"from" display. This option causes this window to resurface
itself if another window ever obscures it. This option can
cause really nasty behavior if another application tries to do
the same thing. Useful for login scripts.
-shadow display
Also sends mouse movements and keystrokes to this display. Use‐
ful for demos. Amaze your friends: specify multiple shadows.
-sticky sticky-key
This option is primarily for "lock" keys like Caps_Lock. If a
lock key only seems to work on every other press, try this
option. The sticky option prevents autoup for the specified
key. Look in /usr/include/X11/keysymdef.h for a list of valid
names of keys (remove the leading XK_).
