No synaptics event device found

I've been using arch now for about two months and love it. A good medium between Gentoo, which I have used the most in the past, and Ubuntu, which I tried but gave me too little control. I'm having a small problem with my keyboard/touchpad, and haven't been able to find a solution, although I've tried many. I know it is a synaptics, because:

cat /proc/bus/input/devices:

I: Bus=0003 Vendor=06cb Product=0009 Version=0100
N: Name="Synaptics Inc. Composite TouchPad / TrackPoint"
P: Phys=usb-0000:00:02.0-4.4/input1
S: Sysfs=/class/input/input6
U: Uniq=
H: Handlers=mouse2 event6 ts2 
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=3

I followed the wiki, so my xorg.conf is set up as recommended there, except for the following:

Section "InputDevice"
      Identifier  "Touchpad"
      Driver      "synaptics"
      Option      "Device"       "/dev/input/mouse2"
      Option      "Protocol"     "auto-dev"
      Option      "LeftEdge"     "1700"
      Option      "RightEdge"    "5300"
      Option      "TopEdge"      "1700"
      Option      "BottomEdge"   "4200"
      Option      "FingerLow"    "25"
      Option      "FingerHigh"   "30"
      Option      "MaxTapTime"   "180"
      Option      "MaxTapMove"   "220"
      Option      "MinSpeed"     "0.06"
      Option      "MaxSpeed"     "0.12"
      Option      "AccelFactor"  "0.0010"
      Option      "SHMConfig"    "on"
EndSection

The Device option is "mouse2" rather than "mouse0," because that's what I get for cat /proc/bus/input/devices (listed above). Here's the relevant error from the xorg.log:

(II) Synaptics touchpad driver version 0.14.6 (1406)
Touchpad no synaptics event device found (checked 18 nodes)
(**) Option "Device" "/dev/input/mouse2"
(**) Option "SHMConfig" "on"
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"
(II) UnloadModule: "synaptics"

The keyboard is a Thinkpad USB keyboard, which gives me a trackpoint and (I wish!) scrolling on the touchpad.

UPDATE, 5 minutes later:
OK, now this is weird. I just tried it again, restarting X, and forcat /proc/bus/input/device I get

I: Bus=0003 Vendor=06cb Product=0009 Version=0100
N: Name="Synaptics Inc. Composite TouchPad / TrackPoint"
P: Phys=usb-0000:00:02.0-4.4/input0
S: Sysfs=/class/input/input5
U: Uniq=
H: Handlers=mouse1 event5 ts1 
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=3

Weirder still, the next time I look at/proc/bus/input/devices , I get the same as the first output listed above!

There are various things I've seen, including this one. It says something aboutn udev rules, which I know nothing about. If anyone can help, I'd appreciate it.

Possible help? Something to do with the psmouse module protocol:http://www.linuxquestions.org/questions … vice+found

Re: No synaptics event device found

It might be a silly question, but did you install the X synaptics driver?

pacman -S synaptics

Re: No synaptics event device found

Yep -- I followed the wiki!
Actually, I also had another look at the /proc/bus/input/devices, and now I have TWO listings for synaptics. I have no idea what to do with this! Here's the entire listing:

Re: No synaptics event device found

Same problem here, they must have messed up the Synaptics driver...

This is my devices stanza:

I: Bus=0011 Vendor=0002 Product=0007 Version=92b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio4/input0
S: Sysfs=/devices/platform/i8042/serio4/input/input6
U: Uniq=
H: Handlers=mouse0 event6 
B: EV=b
B: KEY=6420 0 3000f 0 0 0 0 0 0 0 0
B: ABS=11000003

I can only move the mouse and the touchpad clicks are lost, which is very annoying!

Re: No synaptics event device found

I assume you are not using Xorg 1.8 from testing, but rather are using a 1.7.* version.

you might try look through the output of lshal (it can be long, so I would pipe it through less and search for 'symantic') If you find it, look at what the options are set to.

Xorg 1.7, by default, looks to hal for configuration information -- It will ignore xorg.conf directives.  To tell hal about it, you will need to create an fdi file.  This thread might help: http://bbs.archlinux.org/viewtopic.php?id=96409

Re: No synaptics event device found

I agree with ewaller. It happened to me did you installed "xf86-input-synaptics" and then copy the policy from "/usr/share/hal/fdi/policy/10osvendor to /etc/hal/fdi/policy" , this assuming that you are using the "hal" to detect your hardware.
