3-button PS/2 mouse not working

3-button PS/2 mouse not working

Post by John Goerze » Mon, 08 Sep 1997 04:00:00


I have a Mouse Systems Optical Mouse.  When it is hooked up to the
serial port, it works fine.  When I hook it up to the PS/2 port (using
the supplied adapter), XFree86 thinks that the middle button is the
right button (meaning that both the middle and right buttons do the
same thing).

This is Linux 2.0.29, XFree86 3.3.

How do I fix this?

1. Mouse Systems 3-button "PS/2 Mouse" - Will it Work?

I just purchased a Mouse Systems 3-button PS/2 Mouse to replace a 2-button
mouse (the user couldn't stand using chorded middle).

Unfortunately, I can't get it to work with either gpm or Xree86.  The
mouse will move up and to the right, but simply jumps when you attempt to
move left or down.  I mostly tried /dev/mouse -> /dev/psaux, but the other
options (/dev/inportbm, etc. don't seem to work, either).

It's not a hardware problem, as the mouse works fine under Win95.  I'm
beginning to suspect and incompatibility with the linux PS/2 mouse driver.

Does anyone have any ideas/experience?

Also, I can't get test-mouse to work with ANY mouse I have, most of which
work fine with gpm and XFree86.  Anyone else?
