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.

What mouse does it identify? Also, do you have kcm_touchpad module
installed?

[dtor@dtor-d630 ~]$ rpm -qa "kcm*touchpad*"
kcm_touchpad-0.3.1-6.fc15.x86_64
[dtor@dtor-d630 ~]$ locate kcm_touchpad.so
/usr/lib64/kde4/kcm_touchpad.so

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

It could but it most likely is as most distributions install and set up
synaptics X driver by default. I am not sure what DE Greg is using
though.
