Yes!  This works good.  I have made two devices out of my mouse with this
program and X and the console work with the same device now.

One minor irritation:  gpm uses a different scheme for the buttoning than
X11 with the emulate 3 buttons.  On my particular setup, if I am in a
virtual terminal, and I use X11's paste button, it will paste in the
"focused" X11 app which  - is not visible - .  X11 and the terminal of
course have different buffers.

Other than this (prob unavoidable) side effect, all is well.

Files I had to change:

etc/X11/XF86Config:

# **********************************************************************
# Pointer section
# **********************************************************************

Section "Pointer"
    Protocol    "PS/2"
    Device      "/dev/ps2mouse"
# This is the fake device controlled by mconv2
# the real device is "/dev/psmouse"

/etc/init.d/gpm:

#!/bin/sh
#
# Start Mouse event server

test -f /usr/bin/gpm || exit 0

TYPE=bare

case "$1" in
  start)
     echo "Starting gpm"
     /usr/local/bin/mconv2 /dev/psmouse -ms /dev/mikemouse -ps2 \
	/dev/ps2mouse -mse /dev/msemouse &
     /usr/bin/gpm -t bare -m /dev/mikemouse
     ;;
  stop)
     /usr/bin/gpm -k
     ;;
  *)
     echo "Usage: /etc/init.d/gpm {start|stop}"
     exit 1
esac

exit 0
_______________________

Note: I use two of the three 'fake' devices, I am not sure if both can use
the same device or not, but I don't think so.  I use ps2 for X and microsoft
"mikemouse" for gpm.

If the mconv2 command does not end in (&) the system hangs.

Also the three fake devices must be made with mkfifo commands as per the
README.

I got the item from a sunsite mirror as listed above.

Thanks!
