* Setting Up a mouse + wheel on a traditional ps/2 port in FBSD 5.3
... and others ... *
1. Must know
ps2 bus : the ps/2 bus is mapped as /dev/psm0
/dev/psm0 : support only 'ps/2' protocol ( moused(8) )
moused : map /dev/psm0 as a virtual port to
/dev/sysmouse (ie like /dev/ttyv0 is a virtual tty)
X : work with the /dev/sysmouse virtual device as input device.
xorg.conf : When setting up "Protocol" to "Auto" the protocol choosed
by X is ps/2 which don't work for me (i don't know how to
use a wheel with it without setting up parms for each apps)
xorg.conf : setting up "Protocol" to "sysmouse" is the best way i find
to use my wheel. /sysmouse/ work "natively" with xterm,
Mozilla, and so on. No needs to change anything.
2. Parameters
/etc/rc.conf :
moused -p /dev/psm0 -t ps/2
/etc/X11/xorg.conf :
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "sysmouse"
Option "Device" "/dev/sysmouse"
Option "Buttons" "5"
Option "ZAxisMapping" "X"
EndSection
3. Some tips
Testing :
1 - kill the moused daemon
2 - set mouse on console : vidcontrol -m on
3 - launch moused on foreground to see if it's work :
moused -f -p /dev/psm0 -t ps/2
4 - press ^C to end
5 - if result are ok, launch moused with your previous parms
6 - set up rc.conf && xorg.conf as above.
7 - try to use a lightweight wm like IceWM or twm to test,
it respect well X parms.
4. Comments
i don't know why, but logoff/login or reboot your computer in order to
get this stuff working properly : first time i set this parms, they
don't work. Because i was almost sure they must work, i rebooted my
computer and they work fine. Perhaps some guy from BSD could
explain ...
My X.log whith the 'sysmouse' protocol :
