Alps touchpad improperly detect as PS2 Generic Mouse. No scroll function at all

[mykrob]

Binary package hint: xserver-xorg-input-synaptics

Obviously the mutlitouch doesn't work in ubuntu, which to me isnt a big deal. However, I am not even able to vertical edge scroll. Any ideas how to at least get basic scrolling working?

Hey mykrob,

Hi, have you had a chance to test if this bug is still present in natty?

If it does (and if you're the original reporter), please boot into natty
and run the command:

  apport-collect <bug-number>

which will update the bug with fresh logs and tag the bug as affecting
natty. (It is best to run this right after reproducing the problem.)

[Matthieu Marechal (mat3582)]

Actually the problem has become worse for me in Natty, as
the trackpad which worked under in Maverick (at least scrolling did and
pasting using simultaneously clicking both mouse buttons),
while it doesn't anymore in Natty.

I also have an ALPS trackpad and it is also detected as
such in Natty:

 xinput --list

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS GlidePoint id=13 [slave pointer (2)]
⎜ ↳ PS/2 Mouse id=12 [slave pointer (2)]

However, as can be seen in the above output, it is also detected as
PS/2 Mouse and this takes precedence, apparently.
I tested which driver was used by

xinput --set-prop 'PS/2 Mouse' 'Device Enabled' 0

which disables the trackpad, while the equivalent for the AlpsPS/2 doesn't do anything.
The following shows that the PS/2 Mouse driver is loaded first:

dmesg | grep 'PS/2'

[ 1.541008] i8042: PNP: PS/2 Controller [PNP0303:KBC,PNP0f13:MOUE] at 0x60,0x64 irq 1,12

[ 13.665067] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio1/input/input8

Does the original bug reporter also see the same output as I did, or is mine a different bug?

[Jean-Claude Le Douaron (jcledoua)]

Exactly the same problem on my HP dm1
Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Mouse id=12 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS GlidePoint id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]

    ↳ HP Webcam-50 id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
    ↳ HP WMI hotkeys

Impossible to disable the touchpad when typing and no scrolling...

I am experiencing the same issue on my ACER 7741Z-4433. Edge scrolling and multitouch do not function.

Sorry, meant to add that I am running Natty, plus the latest synaptics driver:

xserver-xorg-input-synaptics 1.3.99

mykrob, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

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 linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the 'needs-upstream-testing' tag. 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, please comment as to why specifically you were unable to test it and add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.
