Disable Toshiba's Z30 Accupoint on Linux via xinput

Follow these instructions to disable the (sometime strange behaving) Accupoint:

Install xinput

apt-get install xinput

Find the device

$ xinput  | grep "PS/2"
⎜   ↳ AlpsPS/2 ALPS GlidePoint                  id=11   [slave  pointer  (2)]
⎜   ↳ ALPS PS/2 Device                          id=12   [slave  pointer  (2)]

AlpsPS/2 ALPS GlidePoint (ID 11) is the touchpad which works fine.
ALPS PS/2 Device (ID 12) is the Accupoint which I want to disable.

Disable the device during xorg start

$ cat >> $HOME/.xsessionrc <<EOF
xinput disable "ALPS PS/2 Device"
EOF

Restart xorg

The small, blue Accupoint should be disabled.

Profit

No more ghost mouse pointer moves. \o/
