Query no Synaptics: 6003C8. bcm5974. Any hints?

[vitaly_repin]

Hello,

I'm trying to figure out why synaptics stopped to work partially with my MacBook Air.

1) What I can see as an end-user: I can use my touchpad as mouse - movements are detected, click is detected. But no multitouch. No luxury functionality which I had several months ago. (Unfortunately, I was not able to detect which part of upgrade caused the issue. Didn't have time to fix it right after upgrade and now need to configure everything once again ) keyboard works pretty OK, including the "Fn" keys.
2) Xorg is configured through evdev. /usr/share/X11/xorg.conf.d/50-synaptics.conf contains:

Section "InputClass"
Identifier "synaptics-all"
Driver "synaptics"
Option "RTCornerButton" "2"
Option "HorizEdgeScroll" "true"
MatchIsTouchpad "on"
EndSection

I went through /usr/share/X11/xorg.conf.d/10-evdev.conf and commented the lines:

#Section "InputClass"
# Identifier "evdev touchpad catchall"
# MatchIsTouchpad "on"
# MatchDevicePath "/dev/input/event*"
# Driver "evdev"
#EndSection

Just to be sure driver synaptics is used.

3) Kernel: 2.6.39. modules hid_apple, bcm5974 are loaded. usbhid is loaded as well.
4) The package x11-drivers/xf86-input-synaptics-1.4.0 is used.
5) The package x11-base/xorg-server-1.9.5 is used.
6) /var/log/Xorg.0.log shows:

And that's it.

[ 16863.737] (--) bcm5974: no supported touchpad found
[ 16863.737] (EE) bcm5974 Unable to query/initialize Synaptics hardware.

So, I see from this log that "touchpad" was found. Even twice. But no synaptics.
Any idea what can go wrong? At least what is the part where I should start to look into?
Kernel side or X side?

Thanks in advance for any hints!

Actually, that MatchDevicePath should help (or at least cut down the number of warnings).

Hi,

did anyone find a solution? I got the same problem.

Can you please post your xorg.conf?

Thanks a lot .
