Follow these instructions to disable the (sometime strange behaving) Accupoint:
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
The small, blue Accupoint should be disabled.
No more ghost mouse pointer moves. \o/
