ALPS Touchpad' incorrectly detected as PS/2 mouse in 'Inspiron R17 Special Edition (7720)' after upgrading to Ubuntu 64-bit 13.04

[karanga]

Upgraded Dell Inspiron R17 Special Edition (7720) from 64-bit 12.10 to 13.04 using sudo update-manager -d
Upgrade successful but the Alps touchpad is only detected as a mouse with no scrolling support available within Mouse and Touchpad. Alps touchpad was not working in 12.10 but using Dave Turvene's hack:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/606238

  I was able to enable scrolling support on the touchpad. Firmware has been updated to latest release using Dell utility whilst running Windows 8.

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu

lsb_release -rd
Description: Ubuntu Raring Ringtail (development branch)
Release: 13.04

Status changed to 'Confirmed' because the bug affects multiple users.

[Brendan William (bwilliam)]

Tried many patches for this, all failed to build with the current kernel.

Give Dave Turvene's latest 1.3 hack a go

 http://www.dahetral.com/public-download/psmouse-alps-1.3-alt.tbz/at_download/file

I now have two finger scrolling in Ubuntu 13.04 using it.

Instructions for installation on Ubuntu 13.04

Download psmouse-alps-1.3-alt.tbz from the link above
copy the psmouse-alps-1.3 folder to your /usr/src directory.
To do this with a GUI try running sudo nautilus
Once the folder has been moved to /usr/src
cd /
cd /usr/src
(as root) dkms add psmouse-alps-1.3
(as root) dkms autoinstall
(as root) rmmod psmouse
(as root) modprobe psmouse

Go to System Settings
Go to Mouse and Touchpad
Click Mouse and Touchpad tab and tick the selection box next to Two Finger Scroll

Thank you Dave Turvene for all your hard work when Dell and Alps turned their back on this issue.

@karanga
Thank you very much, the fix you recommended works like a charm. My machine is Dell Inspiron 13z 5323. I followed your steps and all is good now.

karanga, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-input-synaptics REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
