Trackpoint scrolling no longer works (Lenovo X300)

[Benjamin von Engelhardt]

Binary package hint: xserver-xorg-input-synaptics

Since an update to maverick meerkat (today, 8.9.2010), on my Lenovo X300 vertikal and horizontal scrolling no longer works. However, I can set it (temporarly) with these commands:

bve@bve-laptop:~$ xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation" 8 1
bve@bve-laptop:~$ xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation" 8 1
bve@bve-laptop:~$ xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Button" 8 2
bve@bve-laptop:~$ xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Timeout" 8 200
X Error of failed request: BadMatch (invalid parameter attributes)
  Major opcode of failed request: 141 (XInputExtension)
  Minor opcode of failed request: 57 ()
  Serial number of failed request: 18
  Current serial number in output stream: 19
bve@bve-laptop:~$ xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Axes" 8 6 7 4 5

I didn't yet look deeper into what I have to change to make it work permanently, but I think it should work out of the box. I have disabled the touchpad, which makes some difference as regards the xinput list description for the trackpoint.
