Hi,

Has anyone managed to get a jog-dial button to work as a middle
mouse button in Linux? I have tried changing the mouse protocol
to imps/2 but that just causes the mouse to jump around, jump around
(great song). The configuration in XF86Config is a bit weird: it has
2 mouse entries:

Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "PS/2"
Option "Device" "/dev/psaux"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "yes"
EndSection

Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Device" "/dev/input/mice"
Option "Protocol" "IMPS/2"
Option "Emulate3Buttons" "no"
Option "ZAxisMapping" "4 5"
EndSection

If I remove the 2nd mouse entry X doesn't start up. What's weird is that I don't think the touchpad is a USB device(?)

Any suggestions most welcome.

Yours,

Jon.
