Hi,

So the problem seems to be that your touchpad does not generate touch events in the bottom area of the pad, or at least in the bottom corners.

Can you run evemu-record again, but this time interactively. So go to a text console (ctrl+alt+f2), log in and then run just "sudo evemu-record", then enter the number (just the numer ie 4) of your touchpad.

Now evemu-record will print any touchpad events. What I want you to do is figure out which areas of the touchpad are insensitive to touches. Note that the touchpad may look at where the touch started, so to test please lift your finger and then put it down at a specific spot, then lift it again, and put it down in another spot.  Using this method can you please try to find out where in the bottom area the touchpad will (and will not) report touches. I'm specifically interested in the touch sensitivity in the following areas:
-bottom left / right corners
-bottom edge at 1/4 1/2 3/4 from the left
-bottom area below the marking indicating the button area, ie try the middle of the left half / right half
 of that area, and also a bit lower then that, so closer to the bottom edge
-middle area of the touchpad (just try a few places here, I expect these all to generate proper touches)

Last can you please copy the attached 50-synaptics.conf to /usr/share/X11/xorg.conf.d/50-synaptics.conf reboot and see how things work then ?

Thanks & Regards,

Hans

Green - sensitive, red - insensitive

This is the area map of sensivity

After the replacement of the .conf file the corner buttons work again even if the touchpad is not feeling the finger touch. That was easy) 
However, the right button stil generates left click events, that's still needs fixing.

Thanks, that is very useful. So the bottom edge of your touchpad does not generate
touch events at all, that is unusual, I've never seen a clickpad which does that before.

I am afraid things are not going to be that easy though, because getting the right button to work, we need to undo the 50-synaptics.conf changes.

For touchpads without buttons, where instead you press the entire pad down, we always wait for a touch before reporting the click to figure out to report a right or left button event. This is necessary as the click sometimes arrives before the touch data.

For your touchpad that means that we won't report any button events at all if you click using the insensitive bottom edge of the touchpad. So you will need to use the area slightly above that edge.

Note that with the latest version we ignore touches starting inside the bottom button area of the touchpad, so you don't need to worry about accidentally moving the pointer when using the bottom area instead of the bottom edge.

Please update to this version, which has all the latest clickpad related fixes including ignoring touches starting inside the bottom area: http://koji.fedoraproject.org/koji/buildinfo?buildID=510791

Upgrading to this version will also restore your 50-synaptics.conf to its original contents. After the upgrade please reboot and give the touchpad a try using the *sensitive* part of the bottom area to click, this way you should be able to both left and right click with a single finger.

Thanks & Regards,

Hans

Hello, Hans!

I've just updated to the new version - both buttons work as planned and the bottom area under the line does not move the pointer, too. That is right.

However, there is still a problem - despite the fact the bottom area does not move the cursor, it is not fully ignored:  two-finger slide on that stripe is still being processed: it rolls the page, for instance. Therefore you are not able to move cursor whilst you are touching the bottom stripe, what I try to do all the time (and, I suppose, most people usually do =) )

Would you please look into this problem as well? It feels to me that the solution might be just the finishing touch to all this discussion.

Thank you for your help!
With respect,
Gleb

Good.

Ah yes, this is a known problem which is due to limitations in the xorg-x11-drv-synapatics code. We are working on a rewrite of the touchpad code which should fix this, but it will be a while before that rewrite becomes available. So for now you will just have to live with this.

Hans

p.s.

I'm still working on figuring out why the bottom edge of your touchpad is insensitive. Can you run the following command in a terminal:

dmesg | grep synaptics

And then copy and paste the output here ? Thank you!

OK, let it be, I'll wait.
Here's my output

$ dmesg | grep synaptics
