ALPS touchpad no longer recognizing 'taps' as mouseclick in 3.3-rc3

ALPS touchpad no longer recognizing 'taps' as mouseclick in 3.3-rc3

[Greg KH]

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?

thanks,

greg k-h

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.

Thanks.

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.

Yes, that solved it, thanks.  The Gnome setting is in the Mouse/Trackpad
option in gnome-control-center.

I have a feeling you are going to get a lot of emails about this issue
when 3.3 is released, good luck :)
