Bug Description

On fresh install of Ubuntu 14.04 on Toshiba Portege Z30 series with both "Accupoint pointing device" and "Touch pad pointing device with multi-touch control" neither are recognised. In system settings the Touchpad tab is absent from System -> Preferences -> Mouse. Basic pointing and clicking is possible.

Note that dmesg reports:
...
[ 1.197365] serio: i8042 AUX port at 0x60,0x64 irq 12
[ 1.197715] mousedev: PS/2 mouse device common for all mice
...
[ 1.826029] hub 2-6:1.0: 3 ports detected
[ 1.866199] psmouse serio1: alps: Unknown ALPS touchpad: E7=73 03 0a, EC=88 b3 22
...
[ 2.901657] input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input6

Typing on the keyboard is seriously hampered by inadvertent touchpad contact because there is no "disable touchpad on typing" option. A workaround to this issue would greatly increase the usability of my computer.

Note BIOS was upgraded to latest version before reporting.

Have also tested in upstream mainline kernel 3.16-rc7 with same results.

Ruth Marsden, the issue you are reporting is an upstream one. Could you please report this problem through the appropriate channel by following the instructions _verbatim_ at https://wiki.ubuntu.com/Bugs/Upstream/kernel ?

Please provide a direct URL to your e-mail to the mailing list once you have made it so that it may be tracked.

Thank you for your understanding.

Summary:

This is fixed in kernel 3.17-rc1.

Detail:

Researching this for my daughter (Ruth Marsden) I've found this issue has been known on the kernel mailing lists for sometime. See http://www.spinics.net/lists/linux-input/msg29123.html.
The issue relates to touchpad devices using the ALPS v7 protocol. These devices are reported in this post to have device info as follows:
         Device ID = 0x73, 0x03, 0x0a
         Firmware ID = 0x88, 0xb*, 0x**
Which includes my daughter's Toshiba Z35 which has this Device ID and Firmware ID = 0x88, 0xb3, 0x22

A kernel patch has been in production over the last few weeks. See http://www.spinics.net/lists/linux-input/msg32703.html and related posts. This patch was added on 9th August and can be found in the Ubuntu kernel daily builds from then and the weekly build at http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc1-utopic/ .
To install this see the "Installing upstream kernels" section of https://wiki.ubuntu.com/Kernel/MainlineBuilds .

We've tested the 3.17-rc1 kernel on my daughter's Toshiba Z35 laptop and can confirm that both touchpad and trackpoint devices work. They are recognised as an AlpsPS/2 ALPS DualPoint TouchPad and the touchpad section now appears in System Settings > Mouse & Touchpad. In particular "disabling while typing" is available and works.

Presumably a kernel with this patch will be released in Ubuntu in due course.
