The synaptics touchpad is not working after a fresh install of ubuntu 12.04.2 on a Toshiba P850. It works fine under windows 8 (it's a dual boot machine).
It appears to be recognised OK in Xorg.0.log
I tried the proposed solution in the linked question:
sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps
..but this does not work.
This message gets logged to syslog but the touchpad is still unresponsive:
Apr 28 20:01:36 foobar kernel: [ 256.386831] input: PS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input17
Edit
This is not a duplicate of:
I have read all related posts I can find but none of them offer a solution.
The touchpad is detected but does not work. It works in Windows 8 (machine is dual boot)
$ egrep -i touchpad syslog

In particular this does not work, it just causes compiz to crash and restart:
$ sudo modprobe -r psmouse
$ sudo modprobe psmouse proto=imps
