Hi, I'm using gentoo on a Dell Inspiron 4030..

I got touchpad working really bad with such xorg.conf section

Seems you've got it mixed up.
Remove that block you've added (it doesn't have any useful setting) and add a path match "/dev/input/event*"
to the snippet that got installed with the driver.

you mean like this??

No, I mean drop that section completely.
xf86-input-synaptics installs 50-synaptics.conf.
Read 'man xorg.conf' about InputClass and add that match into that file.
SHMConfig has been obsoleted by xorg-server 1.8.

I start to think that the problem is my thouchpad been detect as a generic PS/2 mouse

I try /etc/X11/xorg.conf.d/50-synaptics.conf with:

1. did you remove those sections from xorg.conf ? drop that '"AllowEmptyInput"' line too
2. that was literal '/dev/input/event*', not to put a number there

It could also be useful if you add

I add the line /dev/input/event* to 50-synaptics.conf and the MatchIsTouchpad "on" too

I got no errors on Xorg.0.log => http://sprunge.us/HDbO
but KDE still complains about "The touchpad configuration is not supported in this system"

I noticed that X was using some files at /usr/share/X11/xorg.conf.d so I move
all this files to /etc/X11/xorg.conf.d
There is a 10-evdev.conf file:

You're on a correct way to master mixing things up.

First of all, that guide is outdated - xorg-server 1.9 on Gentoo doesn't use hal.
You should have left 10-evdev.conf and 50-synaptics.conf where they were - I only said to edit the synaptics file,
cause due to freebsd, that path match isn't there by default.

Once you those files back (it was safe to leave evdev section for Pointer - those files are parsed in order and synaptics is later),
pastebin the new xorg log.

A minor thing though: is that ""PS/2 Generic Mouse"" actually a synaptics touchpad ? If so, your kernel config is probably wrong.

Sorry if I mess up things.... I didn't know that this guide was outdated

I do what you say..

Xorg.0.log => http://sprunge.us/CjMR

dmesg | grep "PS/2" => http://sprunge.us/hDVh

I have this options marked in my kernel

Is there a tool for configuring alps touchpads as such syndaemon/synclient do for synaptics??

I want to disable touchpad when I'm typing but "alps configuring" searches on google redirects me to
synaptics pages aways. The options as MaxTapTime "0" doesn't work for alps touchpads!

:roll:

No. The touchpad is still recognized as a mouse, not a touchpad. All the synaptics tools won't work unless this is solved. I once wrote to ALPS whether they might want to help, but I never got a reply. :-(

Hi.

My touchpad works fine with these settings in xorg.conf

Hi.

I've been having a *real* *big* trouble with synaptics drivers >=1.3.0: the pointer behaves like crazy and becomes totally out of control. (Driver coded by women, I guess...) I did *not* have these troubles with synaptics 1.2* . But now, of course, the latter's been rigged off portage... :evil:

When X starts, the pointer moves normally for a couple of seconds then progressively stops responding to my finger's moves. It sometimes moves when I apply a very (but *very*) soft pressure on the touchpad and move my finger. But then when I start to move my finger more rapidly, the pointer seems to get hicups and moves by slow bursts. I need to move my fiiiiiiinnngeeeeeer veeeeeeeeryyyyy sloooooooooowlyyyyyy to have that darn pointer move its bloody ass along my screen!

Clicking: forget it!
Double click: forget it!
Scrolling: ah? it works! (vertically at least)

Here are my settings:

@VinzC: first, try to do something about that '/dev/input/mouse0' synaptics part
- as I already said, the idea is to use only event* devices:
- quick and dirty is to fix that 50-synaptics.conf (though for the moment any changes there are overwritten on upgrade)
- a more cleaner would probably require something like matching all touchpads first and ignoring them, then in the next block matching event* touchpad nodes and applying settings to them only

It may not help, but should at least clean up that log a bit.

And /usr/share/X11/xorg.conf.d/ ?

Well, that's the 50-synaptics.conf I was talking about.
I'm unsure, if it helps, but at least it should lower warning cont in the log.
Just try to google that blog post about synaptics driver.

After a couple of try/catch, I've finally made my touchpad work the way I wanted. The problem mainly lied in one value: EmulateTwoFingerMinW. The latter is set to 6 by default but 7 in my case did help quite a bit. Here are the values I changed from the defaults:
