Alps touchpad as PS/2 Generic mouse

Hello. I have ALPS touchpad on my Acer Aspire 1551. It works, but in basic mode: two buttons, touch tap as click and double click. Scrolling and multitouch is not working.
Problem is on the kernel level, because it recognizes my touchpad as simple PS/2 Generic Mouse:

I: Bus=0011 Vendor=0002 Product=0001 Version=0000
N: Name="PS/2 Generic Mouse"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input1
U: Uniq=
H: Handlers=mouse0 event1 
B: PROP=0
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=3

There are no entries about alps in dmesg, about mouse:

[kukman@archbook ~]$ dmesg | grep -i mouse
[    0.629021] mousedev: PS/2 mouse device common for all mice
[    6.721323] input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input1

X server config is insignificant, because X can't see my touchpad, X see it as simple mouse. I've read many bugreports, many topics but nothing. I've sent own bugreports into launchpad on Ubuntu, into kernel bugzilla.

Say me, if you need some another information about my hardware. Thanks.

Re: Alps touchpad as PS/2 Generic mouse

I'm getting the exact same thing on my Acer Aspire One D255. My searches turned up conflicting information on whether my touchpad is ALPS or Synaptics, though, and since it only comes up as a PS/2 mouse I can't confirm either way.

Re: Alps touchpad as PS/2 Generic mouse

Same problem here with my Acer Aspire TimelineX 3820TG. Its Alps touchpad is recognized as generic mouse. Vertical scrolling does work, horizontal scrolling doesn't. Also, no multitouch.
There are complaints all over the internet about this (or a similar) issue since several years. Looks like nobody has found a real solution yet, though after every other kernel update they say they fixed it.

Re: Alps touchpad as PS/2 Generic mouse

I had the same problem here.
About multitouch, I believed ALPS touchpad does not support it.

This might be of interest: https://bugzilla.kernel.org/show_bug.cgi?id=14660

It is an open kernel bug report about ALPS touchpads not being recognized.

Almost the same problem here, Acer Aspire One 721. Vertical scrolling doesn't work on mine at all. I'd be so happy if it did.

Re: Alps touchpad as PS/2 Generic mouse

I'm not shure if it is the same issue...
My girlfriend's netbook (Samsung NF210) had the same problem. Touchpad was found as PS/2 device. It is Elantech touchpad, compatible with synaptics. For me (or her) this helped: Ubuntu bug #681904
If anybody is interested I could provide a compiled psmouse.ko for 2.6.39 x86_64 in the evening.

Re: Alps touchpad as PS/2 Generic mouse

Hey eworm.
I'm having the same problem with a Lenovo Z360.
Definitely insterested in testing the compiled module. Could you upload it somewhere so I can test?

Thanks!

Re: Alps touchpad as PS/2 Generic mouse

I found a (quick and dirty) solution for my Dell E6420. Since one month ago my ALPS touchpad worked with Kubuntu, I downloaded the ubuntu kernel 2.6.39.3 sources from here: https://launchpad.net/ubuntu/+archive/p … .10.tar.gz.

Then I did the following:
0 - unzipped the tarball
1 - cd drivers/input/mouse
2 - make -C /lib/modules/`uname -r`/build M=`pwd` psmouse.ko
3 - (as root) rmmod psmouse
4 - (as root) insmod psmouse.ko

With this procedure at least the vertical scroll works, although it is not recognized by synaptic.

Hope this helps.

Re: Alps touchpad as PS/2 Generic mouse

I prepared an AUR package: http://aur.archlinux.org/packages.php?ID=51343

Or simply use my binary x86_64 package for Linux 3.0-ARCH: http://arch.lugor.de/eworm/x86_64/psmou … pkg.tar.xz

Moved linux-headers from depends to makedepends and tweaked the install file: http://arch.lugor.de/eworm/x86_64/psmou … pkg.tar.xz

Re: Alps touchpad as PS/2 Generic mouse

Hi, I can verify that this AUR package works like a charm for DELL INSPIRON N5110 (aka 15R 2011) with ALPS touchpad.

Cheers and thanks!

Re: Alps touchpad as PS/2 Generic mouse

Gah I also have an ALPS touchpad, but it doesn't work here. Did you have to do anything else after installing the package, like tweak xorg.conf? Getting vertical scrolling to work would so make my week. I have an Acer aspire one 721.

No, xorg.conf is not involved. You need to have xorg input modules (xf86-input-synaptics I think) installed. If you have version v6-1 of my package it does not work out of the box. You may a) reboot, b) reload psmouse (modprobe -r psmouse; modprobe psmouse) or c) install v6-2.

Re: Alps touchpad as PS/2 Generic mouse

Works with Dell Latitude E6520 - xinput identifies the trackpad now as "ImPS/2 ALPS GlidePoint". Thanks!

Re: Alps touchpad as PS/2 Generic mouse

I just installed the package from AUR. The output from dmesg shows:

[19273.916693] input: PS/2 Mouse as /devices/platform/i8042/serio1/input/input17
[19273.942083] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio1/input/input18

I don't seem to have multitouch support. Are there any additional steps that need to be done?

Thanks

Re: Alps touchpad as PS/2 Generic mouse

I've been fooling around with this a while, and I found a file in /etc/modprobe.d/ called psmouse, looks like I had tried forcing psmouse to accept a certain option. I deleted the file, and restarted X.

Voila!

# xinput list
⎡ 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)]

Still no vertical scrolling though. Now to see if some tweaking will get it to work

Re: Alps touchpad as PS/2 Generic mouse

I have a similar problem with a sony vaio SB. My touchpad is recognized as a PS2 generic mouse and I don't have the touchpad tab in mouse settings.
However, vertical scrolling works (other options do not, like horizontal scrolling, disable to type or multitouch)

I tried the aur package and my touchpad was recognized as a AlpsPS/2 ALPS GlidePoint (with the same xinput list as whitehorn). The problem is that I lost the vertical scrolling (I tried some tweaks with gpointing-device-settings and xorg without success).

I removed the psmouse-elantech package : back to starting point!! I will follow this post if someone find a trick to enable the extras options...

Thanks to eworm to give us some hope big_smile

Re: Alps touchpad as PS/2 Generic mouse

I use a Dell E4310, and already had this issue on ubuntu.  The reason seemed to be that upstream didn't want to apply the patches, as said here.

Patching and rebuilding the psmouse module indeed worked for me, but now that I use Arch I haven't really bothered making the scrolling work on the touchpad.  I just wanted to point out why this problem will probably not go away soon...

Re: Alps touchpad as PS/2 Generic mouse

The patch puts the touchpad in a mode with limited abilities, so there is no multitouch support.. ALPS does not want to publish the information necessary for full support of their touchpad for "reasons of intellectual property".

My next laptop surely won't have anything from ALPS in it if they insist on this policy sad

Same here! When disabling the PS/2 Mouse pointer, the touchpad stops working completely. It seems like the touchpad is still not properly detected but the driver is loaded anyways. Tried multiple variants of /etc/X11/xorg.conf.d/10-synaptics.conf with no success. In fact when I define an "InputDevice" instead of an "InputClass", the driver isn't loaded anymore.
Gotta keep on waiting and hoping, I guess.
