It happens in my laptop too. Also, two-finger tapping (for middle-click) doesn't work either.

Likely same issue as bug 320632, though one notes a loss of edge-scrolling and the other does not. The difference could be model-specific.

I got this too, on a Eee 701.

My workaround was to reinstall the previous version of xserver-xorg-input-synaptics (0.15.2-0ubuntu8 - from Alpha3), and then lock it in Synaptic.

The following patch enables multifinger click (where available) even when physical right/middle buttons are available.

See bug 320632 and bug320639 for my other patches

I also confirm on Kubuntu Jaunty Alpha 3 on a Dell Latitude D830.

The multi-finger click patch that Alberto posted, and that is included in the new synaptics driver package breaks the expected behavior for multitouch clicking on my MacBook Pro 4,1, and likely does for newer macbooks/macbook pros and the macbook air series.

The expected behavior for right clicking is to put two fingers on the pad, then click the mouse button. With this patch, I have to place three fingers on the pad and click the button in order to right-click. Removing this patch returns my touchpad back to the expected behavior.

I can confirm that this bug still exists with the latest updates (2/22/09). I cannot tap-click with my touchpad. However, I am using a different input package than synaptics.

Currently Installed: xserver-xorg-input-evdev 1:2.1.1-1ubuntu3

Luke: type:
xinput list

and find the line about your touchpad so as to find it's id (for example you will see "id=7"). Then type:
xinput list-props YOUR_ID

and attach the output

Is there any way to know why it does not work in mine? Maybe it's hardware-specific?

@Luke:
I'll revert the multi-finger click patch in Karmic. Thanks for reporting

@All:
as regards two-finger tapping, the default behaviour is to disable it if the touchpad has physical buttons. You can change this behaviour by setting "Synaptics Click Action" to different values by using "xinput".

Yes, interesting... my one-finger tapping stopped working on my Synaptics touchpad yesterday after an update. My laptop does not support two-finger tapping.

I'm running karmic, and have version 1.1.2-1ubuntu3. The current behaviour of my synaptics touchpad is 2 finger right-click, and 3 finger middle-click. As I understand, the reverse behaviour should be expected because 105_correct_multifinger_click.patch was dropped in 1.1.2-1ubuntu2.

Is anyone else having this problem?

Yes, Karmic definitely shows the wrong behaviour in 2-3 finger clicks. Should we open a new bug about it?
