double-finger scroll and double-finger tapping entangled in synaptics

[Henrik Rydberg]

When the multi-finger tapping is on, and when two-finger scrolling quickly in a window, the right-click menu often appears. Apparently the two-finger scroll and two-finger tap gets entangled. A small patch to the mactel version of synaptics is attached.

Unfortunately, not knowing anything about this code, I cannot say much about regression risks with the patch. To me, it simply looks like an unwanted line in the code.

For clarification, this affects the default synaptics driver in Ubuntu as well as a patched version of synaptics that this bug was originally filed against.

I can confirm the bug.

[Wagner Volanin (volanin)]

I can also confirm the bug with the following configuration in xorg.conf:

Section "InputDevice"
 Identifier "Synaptics Touchpad"
 Driver "synaptics"
 Option "Device" "/dev/psaux"
 Option "Protocol" "auto-dev"

 Option "VertTwoFingerScroll" "1"
 Option "TapButton1" "1"
 Option "TapButton2" "3"
EndSection

But I have tested the patch you sent, and it has not fixed the problem for me.
As you said, by quickly two-finger scrolling, the right-click menu indeed appers.
I might look into a solution, but since I am going into a 30-day vacation right now,
it may take some time.

Just an observation: this BUG has nothing to do with my mactel patch,
since it deals with multifinger tap-clicking, and not with the multifinger
button-click.

This is a VALID BUG that affects EVERYBODY using the original synaptics
driver with the configuration tap-click + two-finger scroll, and it would
be a LOT BETTER if you could submit this bug upstream instead.

Ok. Will add package shortly.

What is that status of this bug - did anyone of you look into finding a different patch, or go upstream with it? If not, I could give it a try upstream.

[Henrik Rydberg (rydberg)]

I sent a patch to Christoph Brill <email address hidden>, who seems to be the new maintainer of the synaptics package, at git://anongit.freedesktop.org/git/xorg/driver/xf86-input-synaptics/. No reply yet.

[William Grant (wgrant)]

This is fixed upstream.

[Timo Aaltonen (tjaalton)]

intrepid has 0.15.2.

[userDepth (binarydepth)]

This is still a bug. It would easily fixed if an option to disable two-finger right click can be disabled. Which in my humble opinion is just a duplicated functionality, touchpads already have buttons for left and rich click. The only thing missing in a touchpad is a scrolling wheel.

[userDepth (binarydepth)]

I fixed this with Synclient in the terminal :

synclient TapButton2=0;

And then added to "sudo gedit /usr/share/X11/xorg.conf.d/50-synaptics.conf"
 :

Section "InputClass"
        Identifier "Default clickpad buttons"
        MatchDriver "synaptics"
        Option "TapButton2" "0"
EndSection

Still have to reboot and see if that works
