Would it be possible for you to test the latest upstream kernel? Refer to . Please test the latest v3.7 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. Please only remove that one tag and leave the other tags. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Vince, thank you for testing the mainline kernel. Could you please provide the information following ?

Hi, after some digging, I'm happy to report that the driver made by Dave Turvene to support the newest versions of the ALPS protocol successfully works with the touchpad on this computer.

driver is at

This driver is not yet perfect (it mostly works but for example from my quick testing only two finger scroll works and edge scroll does not) but I would suggest integrating this patch as it will probably solve a huge number of similar bugs related to misdetection of recent ALPS devices...

Another information : recompiling the alps.c module with DEBUG set, I get the following information :

[ 1922.824279] psmouse serio1: alps: E6 report: 00 00 64
[ 1922.849760] psmouse serio1: alps: E7 report: 73 03 50

[ 1922.869428] psmouse serio1: alps: touchpad failed to enter command mode

Anyway, Dave Turvene's driver allows the touchpad to be recognized as I said in my previous comment.

Hi Christopher, from my current knowledge the bug still exists in upstream kernels (this laptop unfortunately has a "Dolphin v2" touchpad)... You added a "cherry-pick" tag, do you have a patch ready that I could test ?

Vince (vincent-vanackere) wrote :

Hi again,

 There is finally a working patch for this hardware available at
I tested it on my A512 and everything works fine. It looks like the patch was also tested on other hardware by Fedora testers and works fine (see ).
It would be very nice to have this fix backported to ubuntu precise. Thanks !

Vince, given the discussion of the upstream patch is ongoing, I'll mark this Triaged for now. When it's accepted into linux-stable, it would ultimately make it's way down to the development release, for inclusion into prior releases.
