HELP! - Xfree86 ignores my IBM Thinkpad 600E 3-button mouse

[Ingolf Markhof <im at de dot uu dot net>]

Hi!

I recently installed cygwin/Xfree86 on a IBM Thinkpad 600E (a notebook).
Although the 600E has a three button mouse, The middle mouse button is
ignored by cygwin/Xfree86 and I thus can't paste.

I first started X by startx which in turn runs xinit. But as a workaround,
I switched to startxwin.sh which calls XWin to start X. XWin offers the
'-emulate3buttons' option and this allows me to paste by pressing two
mouse buttons at the same time.

But how can I get cygwin/Xfree86 to use the 3-button mouse of the thinkpad?

I tried to change mouse button functionality by 

  xmodmap -e "pointer = 1 3 2"

but had to learn the there is a five (!) button mouse defined:

There are 5 pointer buttons defined.

    Physical        Button
     Button          Code
        1              1
        2              2
        3              3
        4              4
        5              5

but even

  xmodmap -e "pointer = 1 3 2 4 5"

has no effect on mouse functionality. I ever have:

button  functio
  1     select
  2     extend selection
  3     none

Any pointers?
