Xorg 1.8 + Synaptics --- Erroneous Error Messages?

I upgraded to Xorg 1.8, and it seems to working fine. I do get some errors when I start though:
SynPS/2 Synaptics TouchPad no synaptics even device found
(EE) SynPS/2 Synaptics TouchPad: no supported touchpad found
(EE) PreInit failed for input device "SynPS/2 Synaptics TouchPad"

But my touchpad works fine. Anyone know why this is? Is there some further configuration that I need to do? I have already customized the settings a bit in /etc/X11/xorg.conf.d/10-synaptics.conf.

Have y'all seen this, and the contents thereof?

http://bbs.archlinux.org/viewtopic.php?id=95321

There's LOTS of stuff on xorg1.8 and keyboards/touchpads over in the Testing Repo forum, at a cursory glance too.

It doesn't seems applicable, since I have no problem with configuration. I just don't like seeing errors where there shouldn't be any.

I have them too, I'm guessing it's nothing to worry about as everything is working fine including multi-touch.

xorg.conf here for reference.

I get it too. Well, the philosophy is: If it works, leave it! big_smile
But I'd like to know more about it, too. Don't want errors all around.

Re: Xorg 1.8 + Synaptics --- Erroneous Error Messages?

From what I can tell, for most people these errors mean that their touchpad doesn't work at all. I guess we are lucky. But I still hope to find out why Xorg is complaining.

Re: Xorg 1.8 + Synaptics --- Erroneous Error Messages?

I had a similar error. It would find a touchpad at /dev/input/event6 and then again at /dev/input/mouse0.

From what I could figure out. Xorg was applying the synaptic driver to the first instance that was given to it from udev and then when the second instance is givin to it by udev under the mouse0 dev it wasn't there anymore.

My solution was to add this to my  /etc/X11/xorg.conf.d/10-evdev.conf

Section "InputClass"
   Identifier      "disabling synaptic second mouse found"
   MatchProduct    "SynPS/2 Synaptics TouchPad"
   MatchDevicePath "/dev/input/mouse0"
   Option          "Ignore" "on"
EndSection

now my Xorg.0.log looks like this

Re: Xorg 1.8 + Synaptics --- Erroneous Error Messages?

I'm seeing this same error and Xorg won't start with xinit or startx
It starts fine if I use any display manager (I actually only tried slim and gdm)

The day Microsoft makes a product that doesn't suck, is the day they make a vacuum cleaner.

But if they tell you that I've lost my mind, maybe it's not gone just a little hard to find...

@George.Harmony: Ah, nice detective work. Don't have time to check write now, but I will report back if the solution works. Weird problem in the first place. Maybe it should be reported as a bug.

Re: Xorg 1.8 + Synaptics --- Erroneous Error Messages?

George.Harmony: Great! This worked for me,

Although on my laptop, its event10, mouse1 and ALPS.
My 10-evdev.conf looks like this:

...
Section "InputClass"
   Identifier      "disabling synaptic second mouse found"
   MatchProduct    "AlpsPS/2 ALPS GlidePoint"
   MatchDevicePath "/dev/input/mouse1"
   Option          "Ignore" "on"

Re: Xorg 1.8 + Synaptics --- Erroneous Error Messages?

Thank you, thank you thank you!!

This topic really saved my sanity! Xorg added touchpad as a joystick, so it always threw the cursor at the center of the screen. I was using Xorg 1.7 for weeks because of this. I blacklisted /dev/input/event5 and all is perfect now!

PS. I hate Xorg
