With the xorg-x11-drv-synaptics-1.7.4-4.fc20.x86_64 update now there is a different problem on Lenovo Thinkpad T430u (there are additional left and right buttons at the bottom corners of the touchpad)

Description:
Corner buttons of the touchpad do not work properly. Right one will only react to a press when you have a finger of the other hand somewhere on the touchpad, single-finger press will not do. Left works the same as right one, just makes a click if the above condition is met (no context menu)

How to reproduce:
1. Place your pointer above some interactive element with your touchpad, remove finger you've been using to move the pointer and then press one of the corner buttons with your finger or, better, with another object (so it wont be able to move the cursor, only to press the button). You should observe no reaction

2. Place your pointer above some interactive element with your touchpad and, WITHOUT removing the finger you've been using to move the pointer, press one of the corner buttons with another finger or, better, with another object (so two fingers or a finger and an object are on the touchpad simultaneously). You should observe a reaction as to a right-click, however, no matter which corner button you've pressed

Everything else is working well, however I cannot revert to a previous version of the package, which is disappointing

Hi,

Peter is on a short vacation and he has asked me to further help you with this bug.

So what you seem to describe are 2 different things, 1 is a feature and the other is a bug:

1) Clicking in the bottom right area of the touchpad results in a  left click rather then a right click,
this is a bug. But discussing this does not belong in this bugzilla which is about another touchpad bug, so I've filed a new bug, see bug 1086277 for this.

2) Clicking with 2 fingers on the clickpad generates a rightclick. This is a feature it is called clickfinger. This is an alternative way to right click which some people prefer over using the bottom right area of the touchpad.


Lets discuss the real bug 1) further in bug 1086277. Can you please run the following 2 commands and copy and paste their output to bug 1086277:
cat /sys/class/dmi/id/product_version
cat /sys/devices/pnp0/*/id

Please also do the following:

1)
sudo yum install evemu
Switch to a text console, do ctrl+alt+f2 and login there
sudo evemu
Notice which event-node is the touchpad and do:
sudo evemu /dev/input/eventX > evemu.log
click in the right bottom area with a single finger
ctrl+c

2) If you've experience with building code from source, please clone and build:
git://git.freedesktop.org/git/libevdev and then run sudo ./tools/touchpad-edge-detector /dev/input/eventX, paste the output to bug 1086277.
If you don't know howto built from source, instead please do:
sudo evemu /dev/input/eventX > evemu2.log
Then move your finger along the edge of your touchpad (all 4 sides) and after that do ctrl+c.

Attach the generated evemu(2).log file(s) to bug 1086277.

Thanks & Regards,

Hans

Thanks for your answer, Hans! 

I am very sorry for the confusion but I had totally mixed up left and right in my previous comment, it's wonderful you've managed to get it right about the bug 1. I will do what you've asked in a few minutes there in the new file.

Again, sorry for misunderstanding, I was not, however, saying about the two-finger right click. The problem is hard to describe, but I'll try to do it better. 

The *left* corner button, mechanical one, has an insensitive area on it to click without moving cursor. 
But this button only reacts to a *mechanical* click if the touchpad feels the finger on itself (that's not right, that's the real bug 2)
Hence I cannot use the insensitive area to click with one finger, only with addition of another one somewhere on the touchpad, which is sometimes inconvenient.

I hope I've managed to express it all better now,
Respectfully,
Gleb

I think I'm starting to see the problem now, lets discuss this further in bug 1086277.
