[gentoo-user] Synaptics touchpad mistaken(?) for Logitech Wheel Mouse

[gentoo-user] Synaptics touchpad mistaken(?) for Logitech Wheel Mouse

[Johan Blåbäck]

Hi.

Recently I got tired of my touchpad being too sensitive, and I decided
to try the synaptics-how-to on the gentoo-wiki. However, when starting
X I get:

[---]
(==) Log file: "/var/log/Xorg.1.0.log", Time: Thu Mar  6 13:09:00 2008
(==) Using config file: "/etc/X11/xorg.conf"
(II) Module already built-in
(EE) NVIDIA(1): Unable to find available Display Devices for screen 1.
TouchPad no synaptics event device found (checked 17 nodes)
Query no Synaptics: 6003C8
(EE) TouchPad no synaptics touchpad detected and no repeater device
(EE) TouchPad Unable to query/initialize Synaptics hardware.
(EE) PreInit failed for input device "TouchPad"
[---]

(And the touchpad gets turned off.)
The "no synaptics touchpad detected"-part gave me a hint to take a
look at /proc/bus/input/devices, and what I find is... strange:

[---]
I: Bus=0011 Vendor=0002 Product=0005 Version=0063
N: Name="ImPS/2 Logitech Wheel Mouse"
P: Phys=isa0060/serio4/input0
S: Sysfs=/devices/platform/i8042/serio4/input/input4
U: Uniq=
H: Handlers=mouse0 event4
B: EV=7
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=103
[---]

I don't know much about this, but that does not seem to be a touchpad
(I'm very sure it's not my (usb) mouse).

For some time I lost hope of ever getting it to work. But then I
accidentally boot a ubuntu Live, and then my touchpad worked without
any problem. I compared the xorg.conf's (mine and ubuntu-live) and
they are the same.

So what I suggest could be the problem is that I got my kernel wrong,
since it seem to emulate Logitech instead of synaptics. But I don't
know if that is the problem, or how I fix it. (I have all the kernel
options that the gentoo-wiki synaptics-how-to recommends.)

Thanks for any suggestions!

I suspect you need these options in your kernel:
Device Drivers
 Input Device Support
  Event Interface (CONFIG_INPUT_EVDEV=y)

I also have:
..
  Mice
   PS/2 Mouse
and all the sub-options compiled in:
CONFIG_INPUT_MOUSE=y
CONFIG_MOUSE_PS2=y
CONFIG_MOUSE_PS2_ALPS=y
CONFIG_MOUSE_PS2_LOGIPS2PP=y
CONFIG_MOUSE_PS2_SYNAPTICS=y
CONFIG_MOUSE_PS2_LIFEBOOK=y
CONFIG_MOUSE_PS2_TRACKPOINT=y

that's nice to know.  Just so this email is accepted by your security
policy, I double-rot13'd the reply.  Note that your comments are now
quadruple-rot13'd, but I think you should be able to decrypt them
without too much hassle.

Wow, the encryption on this thing now! NSA might get confused.

hm.  Do you have INPUT_DEVICES="... synaptics" in /etc/make.conf?

I don't think your /proc/bus/input/devices looks quite right - are you
sure this isn't a pointer stick or something?  What's the complete file
look like?

Yes, just as the gentoo-wiki says:

INPUT_DEVICES="evdev keyboard mouse synaptics"

I'm not familar with the term "pointer stick". I'm not at my computer
right now, but I'm sure that that is my touchpad... to about ~90%. If
I have an USB-mouse plugged in, I can see that mouse and my touchpad
(ImPS2 Logitech wheel mouse). When I unplug my USB-mouse I see my
touchpad(?) (ImPS2 Logitech wheel mouse) and... my touchpad(?)
(Generic PS/2 mouse). I can get you the whole output when I come home.

I found a thread on ubuntuforums with people having the same problem.
But ubuntu have PS2MOUSE as module, and one solution is to reload that
module in, for example gdm. Which I see as a hack that I rather not
do, but I'll try it. If ou are interested for the problem I'll get the
forum thread URL later.

This did not work...

Another thing that is different from my problem from the ubuntu
problem (which I can't recreate) is that they get a synaptics device
when running `tpconfig -i`, which I do not.

a pointer stick is a stupid little button-like think in the middle of
your keyboard (usually at the intersection of the g, b, and h keys).
You push it in a direction, and the mouse starts moving in that
direction.  They were popular before touchpads were standard.  Anyway,
if you don't have one, then good!

ok.  Are you sure it's a synaptics touchpad?  Otherwise I'm out of
ideas, sorry...

Nope, don't have one of those.

Yes, I'm sure. When booting a Ubuntu Live >= 7.04 I get a synaptics
touchpad, detectable and all.

Hello Iain and Johan,

I didn't want to hijack the thread, so I waited till this moment. I
can report a similar problem on my laptop.

The symptoms are pretty much the same as those described by Johan.
However, in my case the Touchpad worked fine (for example, sliding the
finger on the far-right side correctly translated into scrolling). It
was  (more or less) after I used a couple of times my Logitech USB
Mouse that the Touchpad defaulted to basic mouse functionality (two
buttons and "mouse pointer" movement).

At that time I was convinced it was a "coldplugging" problem. When I
found some more free time, and after having survived an "emerge
world", I switched to a (completely) dynamic udev. Still, this did not
solve the problem. Then I was blocked. Following the Wiki Howtos for
configuring the Touchpad did not help much, either.

How do you think that I could verify that this is a "coldplug/udev"
problem? Could this be the problem, at all? What information that
would help you help me pin-point the problem could I post?

Thanks,
Liviu

I know nothing about this (udev), so any outside input to this
discussion would be good.

After running all the tests suggested in this thread (including kernel
configuration, make.conf, tpconfig, /proc/bus/input/devices), I find
myself in pretty much the same situations as you are.

Today, when re-compiling the kernel, I found this link [1] to the
synaptics project, suggesting troubleshooting methods. Looking at
their Changelog [2], synaptics [3] looks kinda dropped out of
maintainance; the latest version "Made the driver work with xorg 7.1".
If you're on 7.3, like I am, who knows whether it works. A last
suggestion, try upgrading synaptics to the last unstable version,
update the config files and cross your fingers.

Regards,
Liviu
