Subject:   How to disable touchpad in FreeBSD 10.3
Message-ID:  <alpine.BSF.2.00.1609221406310.21592@lighthouse.safeport.com>

In FreeBSD 10.1 the touchpad on my laptop could be disabled by:

    moused_enable="YES"
    moused_port="/dev/ums0"

resulting in starting moused with:

    /usr/sbin/moused -p /dev/ums0 -t auto -I /var/run/moused.ums0.pid

With Xorg 7.7_2 and FreeBSD 10.1 this worked. E.g., /dev/psm0 was not available 
to Xorg. With FreeBSD 10.3 and Xorg 7.7_2 as you can see from the marked lines 
[**] in 10.3 this starts /dev/psm0 also.

I would like to disable psm0 without compiling a custom kernal. Options would 
seem to be a custom driver or input section in /usr/local/etc/X11/xorg.conf.d 
but the man files show no options to do this. sysctl for dev.psm.0 does not have 
any options I can see would do this available values:

    hw.psm.tap_timeout: 125000
    hw.psm.tap_threshold: 25
    hw.psm.tap_enabled: 0
    dev.psm.0.%parent: atkbdc0
    dev.psm.0.%pnpinfo:
    dev.psm.0.%location:
    dev.psm.0.%driver: psm
    dev.psm.0.%desc: PS/2 Mouse
    dev.psm.%parent:
    dev.psmcpnp.0.%parent: acpi0
    dev.psmcpnp.0.%pnpinfo: _HID=SYN1E4B _UID=0
    dev.psmcpnp.0.%location: handle=\_SB_.PCI0.LPC0.PS2M
    dev.psmcpnp.0.%driver: psmcpnp
    dev.psmcpnp.0.%desc: PS/2 mouse port
    dev.psmcpnp.%parent:

man xinput has an operand that would seem to do it:

    xinput --disable device
      device can be the device name as a string or the XID of the device.

What do I use for the device. On my system xinput shows:

     Virtual core pointer                     id=2    [master pointer  (3)]
     Virtual core XTEST pointer               id=4    [slave  pointer  (2)]
         sysmouse                             id=7    [slave  pointer  (2)]
         Mouse                                id=8    [slave  pointer  (2)]
     Virtual core keyboard                    id=3    [master keyboard (2)]
      Virtual core XTEST keyboard             id=5    [slave  keyboard (3)]
      kbdmux                                  id=6    [slave  keyboard (3)]

I think I want id=8  [slave  pointer  (2)], but how to specify that?
