Hi,

This problem has been since 3.3-rc1, but I only now am getting around to
reporting it, sorry about that.

In 3.3-rc3, my alps touchpad isn't recognizing a tap on the touchpad as
a mouse click.  Is there a new Kconfig option that I need to enable?

My /proc/bus/input/devices entry for this thing is:
I: Bus=0011 Vendor=0002 Product=0008 Version=7326
N: Name="AlpsPS/2 ALPS DualPoint TouchPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input6
U: Uniq=
H: Handlers=mouse1 event6
B: PROP=8
B: EV=b
B: KEY=e420 70000 0 0 0 0
B: ABS=260800001000003

Is there anything else you need me to report to help track this down?

Please make sure you have xorg-x11-drv-synaptics installed and then
check if tap to click is enabled in your DE. I think Gnome for some
reason has it off my default.

Is this a new thing for the 3.3 kernel?  I ask as 3.2 and older kernels
work just fine this way.  I can do a 'git bisect' to track it down to a
specific patch if that will help out.

No, there is no need. I am pretty sure pre-3.3 your touchpad worked in
PS/2 compatibility mode; in 3.3 we merged support for native multitouch
protocol so your touchpad works in absolute mode, can support various
gestures (vertical/hrizontal scroll, user-selected sensitivity, etc.)
and is recognozed as a proper touchpad by the entire stack. For some
reason though Gnome has disabled tap to click for touchpads by default.
I do not remember what is the default for KDE.

Hope this helps.

Since I'm using the same ALPS touchpad as Greg, I might be of some help here.

I don't know how to check whether my touchpad is in absoulte mode or
not, but KDE system settings ->  input devices doesn't list any
additional touchpads at all, only a mouse. Which affects both mouse
and touchpad.

Could this be not a DE, but a xorg/driver problem afetr all?

As I messed up sending previous letter, to what Greg has pointed me, I
will quote myself:

Can't confirm this.

Sony Vaio VPCEH2L1R (p.d. November 2011)
archlinux, 3.3-rc3 (linux-mainline from AUR)

I: Bus=0011 Vendor=0002 Product=0008 Version=7326
N: Name="AlpsPS/2 ALPS DualPoint TouchPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input12
U: Uniq=
H: Handlers=mouse2 event12
B: PROP=8
B: EV=b
B: KEY=e420 70000 0 0 0 0
B: ABS=260800001000003

/etc/X11/xorg.conf.d/10-synaptics.conf :

Section "InputClass"
   Identifier      "touchpad catchall"
   Driver          "synaptics"
   MatchIsTouchpad "on"
   MatchDevicePath "/dev/input/event*"
   Option          "SHMConfig" "on"
   Option          "TapButton1" "1"
   Option          "TapButton2" "2"
   Option          "TapButton3" "3"
   Option          "VertTwoFingerScroll" "on"
   Option          "HorizTwoFingerScroll" "on"

Works okay and worked with 3.3-rc2 (and earlier).
