Laptop ALPS touchpad not detected, not working

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

Does look similar to bug 359982, but I don't have the knowledge to determine if the cause is the same.

Looks like a kernel issue, as there's no sign of a touchpad in the HAL listing.

If it is a kernel issue, what should I do to fix it? I'm new to linux/ubuntu/xubuntu, so any help would be greatly appreciated. Thanks!

Hi dadrivr,

There are still a few things you can do to help us debug this issue.

1) Did this device ever work? perhaps with an older version of Ubuntu, or an older kernel? If so, please describe.
2) Please try a mainline kernel and let us know how it goes. Please try the 2.6.30 mainline kernel. How to do this is explained here: https://wiki.ubuntu.com/KernelMainlineBuilds.

If the mainline kernel works, let us know, of course.

If it does not work, could you please boot into the kernel with the options "i8042.debug=1" attached to the end.

Modify /boot/grub/menu.lst. It should look somwhat like this afterwards:
title Ubuntu 9.04, kernel 2.6.28-11-generic
uuid dcc2f6bc-6e72-48f6-912d-6032287e7eb1
kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=dcc2f6bc-6e72-48f6-912 i8042.debug=1
initrd /boot/initrd.img-2.6.28-11-generic
quiet

Thanks for your report.

I just uninstalled Xubuntu, formatted my hard drive, and installed Ubuntu 9.10 (Karmic Koala). Unfortunately, my touchpad still does not work. It used to work with Windows, but has ceased working since I switched over to Linux. Do I still need to try a mainline kernel even though I updated Ubuntu?

Here is some output that may help you diagnose my problem:

I had a similar problem, in that my ALPS touchpad wasn't detected, but different in that it still functioned as an ImPS mouse. This is now fixed in Lucid (see bug #129477), perhaps this bug is also fixed by this?

I have the same issue with a laptop gigabyte m1405: Touchpad do not work neither under X, neither with gpm.

It is detected as a "Macintosh mouse button emulation"

in dmesg:
input: Macintosh mouse button emulation as /devices/virtual/input/input4

in /var/log/Xorg.log:
(II) config/udev: Adding input device Macintosh mouse button emulation (/dev/input/event4)

but from dmidecode:
Handle 0x000D, DMI type 21, 7 bytes
Built-in Pointing Device
        Type: Touch Pad
        Interface: PS/2
        Buttons: 4

I have solved the problem on my laptop gigabyte m1405.
I had the same symptomes and to fix this issue i had to:

1- patch the kernel file drivers/input/serio/i8042-x86ia64io.h to enable the "noloop" option for my laptop model.
See attached file.

To find the DMI_BOARD information, you can use dmidecode and look at the "Base Board Information" section:
# sudo dmidecode

2- disable Macintosh device support in the kernel configuration (it seems to works OK with, but in doubt, i remove it and anyway it won't hurt you as you don't use a Mac, i suppose).
do not select the option : "Devices Drivers > Macintosh device drivers"

3- again in your kernel configuration, enable PS/2 support if not selected :
"Devices Drivers > Input Device > Mice > PS/2 Mouse"

Then recompile your kernel and install it. The touchpad shall work without extra configuration.
Verify using the command "dmesg" that the auxiliary port (for mouse) is detected and the synaptic driver is loaded.

# dmesg | grep 8042
[ 4.597919] serio: i8042 KBD port at 0x60,0x64 irq 1
[ 4.597932] serio: i8042 AUX port at 0x60,0x64 irq 12

[ 18.617879] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input5

Good luck!

This patch enables the option noloop in the i8042 driver for the laptop gigabyte m1405.
If you have the same symptoms has described below (i.e. auxiliary port is not correctly handle) you can try this:
using the dmidecode command, find your board information and add it to the noloop table.

Best regards,

Ludovic

I have a similar situation, with touchpad being detected as "ImPS/2 Generic Wheel Mouse":

Guided by this, I've installed kernel sources to the Ubuntu kernel, disabled the Macintosh drivers and patched i8042-x86ia64io.h, adding my system to i8042_dmi_noloop_table:

Note that in the .matches field, I've used the system information data from dmidecode, not from base board. That's because the base board data reported on my laptop looks to generic as you can see below - the product is simply "VAIO" and there's...

BTW, answering Kevin DuBois, I've tried with the mainline kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-lucid/ - it doesn't solve the problem.

Now I'll try booting with i8042.debug=1 kernel argument and let you know what it logs.

Here's the log from i8042.debug=1, grepped for the "8042" string:

Hi Aleksander,

Did you enable synaptic support in the kernel?
Do you have synaptic packages installed?
Can you report the result of?
# dmesg | grep 8042

As well, i forget to post that one shall be able to change those nomux, and noloop parameters for the driver i8042 by passing to the kernel the parameter 'i8042.nomux=1' and/or 'i8042.noloop=1' in grub/lilo.

1) Synaptics support is present:

# grep -i synapt /lib/modules/`uname -r`/build/.config
CONFIG_MOUSE_PS2_SYNAPTICS=y
CONFIG_MOUSE_SYNAPTICS_I2C=m

2) Synaptincs X.org package is present:

# dpkg -l | grep -i synap
ii xserver-xorg-input-synaptics 1.2.2-1ubuntu4 Synaptics TouchPad driver for X.Org server

3)

# dmesg | grep 8042

For now, the workaround I use is disabling the touchpad device using XInput - I've written a script which is run during KDE session startup:

# cat disable_touchpad.sh

#!/bin/sh
xinput set-prop 'ImPS/2 Generic Wheel Mouse' 122 0

on gigabyte 1405 all i had to do is to update GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grup like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux i8042.noloop"
and run:
$ sudo update-grub
$ sudo reboot

After upgrading to Kubuntu Natty, I no longer have the problem.

The KDE Input Settings/Touchpad KControl Module (which seems largely redesigned) allows reconfiguration and correctly reports the device as AlpsPS/2 ALPS GlidePoint.

For some reason, this bug didn't show up as related, so I filed #616605. This might be a duplicate, but I still have this problem under natty.

This bug was filed against a series that is no longer supported and so is being marked as Won't Fix. If this issue still exists in a supported series, please file a new bug.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.
