apport information

** Description changed:
Since the kernel upgraded from 4.4.0-31-generic the touchpad on my
Toshiba Tecra laptop has not been functioning correctly.
Whenever I try and do two finger srcolling it also thinks I'm doing a
two finger tap to to rightclick, making two finger scrolling almost
impossible.
It is the same for both kernel updates since 4.4.0-31. If I boot from
4.4.0-31 then the touchpad works fine.
If I do an xinput in the later kernels it shows :-
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer
(2)]
⎜ ↳ Microsoft Wired Keyboard 600 id=10 [slave pointer
(2)]
⎜ ↳ Microsoft Comfort Mouse 6000 id=11 [slave pointer
(2)]
⎜ ↳ AlpsPS/2 ALPS DualPoint Stick id=15 [slave pointer
(2)]
⎜ ↳ AlpsPS/2 ALPS DualPoint TouchPad id=14 [slave pointer

⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave

↳ Power Button id=6 [slave

↳ Video Bus id=7 [slave

↳ TOSHIBA Web Camera - FHD id=12 [slave

↳ AT Translated Set 2 keyboard id=13 [slave

↳ Toshiba input device
The AlpsPS/2 devices aren't aren't present when booting with 4.4.0.31:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer
(2)]

Any ideas?
Thanks.
