Getting a PS/2 Microsoft Cordless Wheel Mouse working correctly under X-windows

takes a litte bit of tweaking.



In the Pointer Section of /etc/X11/XF86Config, set the following:



    Protocol    "MouseSystems"

    Device      "/dev/gpmdata"



Then, make your gpm start like so:

    gpm -R -t imps2



You should be all set. (Of course ;-), this doesn't get the scroll mouse

working, only the button.



To explain:

-gpm's "-t imps2" option reads the mouse input as if it were a "Microsoft

Intellimouse (ps2) - 3 buttons, wheel unused".

-Then gpm's "-R" option pushes mouse output to /dev/gpmdata in the

"MouseSystems" format.

-So you have to set X-windows to read the new device in the new format.





You can also control mouse speed and acceleration and other things from 

gpm. Check it out.









Here's a snippet of my /etc/X11/XF86Config

Section "Pointer"



# To make my "Microsoft Cordless Wheel Mouse Serial and PS/2 Compatible"

# work, I have to set the following:

# -Protocol set to "MouseSystems" (because that's what the /dev/gpmdata

# device outputs)

# -Device set to "/dev/gpmdata" (because, when I set "gpm -R ..." that's where

# it gets output to, instead of /dev/mouse

# -I run "gpm -R -t imps2 -a 1" which says:

#    -R        process the output through gpm and out to /dev/gpmdata

#    -t imps2  read the mouse as a 3 button Microsoft Intellimouse

#    -a 1      set the acceleration from the default of 2 to 1

#

#  So I'll bet you're wondering why I port the mouse through

#  "-R" --> "/dev/gpmdata". After all, it shouldn't make a difference...

#  should it?  Well, for whatever reason, it DOES make a difference. So

#  I do it and don't ask questions.
