So I am now getting Absolute X/Y (which is what I want) but when I do startx
the mouse is not working correctly.

NOTE: I have following enabled via /etc/rc.conf:

dbus_enable=3D"YES"

All other mouse/pointer related items are commented out (ie disabled):

#moused_enable=3D"YES"
#hald_enable=3D"YES"

The xinput indicates that the evdev driver has not loaded and Xorg is
defaulting to mouse_drv:

<<XINPUT>>

<<END XINPUT>>

So issue is now how to get evdev input device connected to xorg...

can you provide any tip / link on this ?

Thank you.

Cheers,
