This is very likely an X issue, not a GNU Emacs issue.  I would like a
work around.

How do I prevent a region being pasted twice when I copy the primary
region with my mouse from GNU Emacs to an xterm or an RXVT shell in X?

Doubling also happens when I copy a command from one xterm to another.
That suggests the problem is an X issue.

However, doubling does not happen when I go from an xterm to GNU Emacs.
Also, doubling does not happen between two RXVT shells.

I am using the Debian Testing distribution of GNU/Linux, updated this
morning.

Do you have a three button mouse, or are you using middle button
emulation?

Which driver do you use, mouse or evdev?

Is the mouse ps/2 or usb?

If the mouse driver is loaded and listening on /dev/input/mice and evdev
is also loaded and listening on the /dev/input/evdev* devices you could
be getting two X events for each button press/mouse movement.

The X logs would give some clues if that is the case.

Or, if you're middle button is also a wheel, a slight forward or
backward movement when pressing it could lead to a double event.

If you are using middle button emulation, there could be some issue with
the timeouts.

These are all guesses, of course.

three button

    Is the mouse ps/2 or usb?

ps/2

My /etc/X11/xorg.conf file:

	Identifier	"Generic Mouse"
	Driver		"mouse"
	Option		"CorePointer"
	Option		"Device"		"/dev/psaux"
        Option		"Protocol"		"PS/2"
       
Occasionally, I plug in a USB mouse with a wheel that I can use as a
center button, but have not recently.  I have not plugged it in when I
had double pastings.  For my USB mouse, even though it is not plugged
in, my /etc/X11/xorg.conf file has a section that says:

        Identifier	"USBMice"
	Driver		"mouse"
        Option	        "Protocol"              "IMPS/2"
        Option	        "Device"                "/dev/input/mice"

I do not have evdev* in /dev/, /dev/input/, or /etc/X11/xorg.conf

/var/log/Xorg.0.log says:

Try removing that.  /dev/input/mice already functions as a multiplexer
for all mouse events in the system.

No success.

    Try removing that.  /dev/input/mice already functions as a multiplexer
    for all mouse events in the system.

I tried, as a different user, starting from a different virtual console
and starting X (with an Enlightenment window manager, as I normally
have).  In the cases where X started, I pasted doubles from `emacs -Q
-D' to an xterm as before.

I could start X when I had everything in my /etc/X11/xorg.conf file
except that I changed /dev/psaux to /dev/input/mice.  That section
looked like this:

	Identifier	"Generic Mouse"
	Driver		"mouse"
 	Option		"CorePointer"
# 	Option		"Device"		"/dev/psaux"
 	Option		"Device"		"/dev/input/mice"
        Option		"Protocol"		"PS/2"

Similarly, I could start X when I commented out most parts of that
section but left the Driver as "mouse".

	Identifier	"Generic Mouse"
	Driver		"mouse"
# 	Option		"CorePointer"
# 	Option		"Device"		"/dev/psaux"
# 	Option		"Device"		"/dev/input/mice"
#       Option		"Protocol"		"PS/2"

Those gave me doubles.

I could not start X when I commented out those options plus the driver
or those options plus the driver plus the identifier.

Andreas' suggestion is that your USBMouse section, which references
/dev/input/mice, is all that you need.  The separate Generic Mouse
section becomes superfluous.  (And is exactly what I was going to write
until I saw his reply.)

So you only need one mouse section which specified /dev/input/mice;
it will handle every mouse you plug in.

Success!  After seven tries with various configurations.  Thank you.

Done.

I never would have thought of it.  I put the entry at the end of the
section on ** General X problems in a subsection with three asterisks.
