After the last update yesterday:

[I] x11-drivers/xf86-input-synaptics
Available versions: 1.4.0 ~1.5.2 1.6.2-r1{tbz2} ~1.6.3 ~1.7.0
Installed versions: 1.6.2-r1{tbz2}(17:38:53 22.04.2013)
Homepage: http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/
Description: Driver for Synaptics touchpads

finger tapping and edge scrolling doesn't work anymore. I have a minimal 80-touchpad.conf in xorg.conf.d:

Section "InputClass"
Identifier "touchpad"
Driver "synaptics"
Option "SHMConfig" "on"
Option "VertEdgeScroll" "1"
Option "HorizEdgeScroll" "1"
MatchIsTouchpad "on"
EndSection

which used to work up till now.

The relevant portion of Xorg.log

Any hint on what's going on here will be appreciated

I wonder if this is the problem:

Code:
[  2881.968] (**) SynPS/2 Synaptics TouchPad: Ignoring device from InputClass "touchpad ignore duplicates"


I use the same driver version; here's my touchpad conf:

Code:
Section "InputClass"
   Identifier "touchpad catchall"
   MatchIsTouchpad "on"
   Option "HorizEdgeScroll" "on"
   Option "VertEdgeScroll" "true"
EndSection

Note that I don't specify the driver, and that I leave tapping turned off since I only use the touchpad for scroll.

Thanks Hypnos,

as it seems, the identifier did the trick. As I understand it so far, there seems to be a standard identifier with the name "touchpad" so my directive gets ignored. After setting it to "touchpad catchall" all is running fine now.
