When I touch my touchpad and move the finger to right at some point the
cursor instantly jumps to the right edge of the screen. When I move the
finger back and cross this line again, but now from right to left, the
cursor instantly jumps from the right to the left edge of the screen.
The vertical line, which I must cross to notice such a strange behaviour
is placed at about 1/5 of touchpad's width from the right, so it may be
border of scrolling area. I have synaptics touchpad. I noticed this bug
a week ago and suspect that it's a regression at version 1.1.3 of xf86
-input-synaptics.

is the output different between 1.1.2 and 1.1.3?

weird. there's only one patch between 1.1.2 and 1.1.3 and that was the
removal of the auto-scaling of the right edge (which broke scrolling on
every touchpad I tested/emulated). just to be sure, please check that
there aren't any distro-specific patches that may affect this.
If you remove the settings for the touchpad (except the edge scrolling on) from the config file do you still see the issue?
please enable shmconfig and run synclient -m 20 while moving the finger across this line. At what coordinates does the cursor jump?
also, I think the log file may help at this point, please attach this as well.
I'm beginning to think that the issue may be coordinates outside the
kernel-reported range (which may make this a semi-duplicate of #23102).

But I have a problem with running synclient -m 20. It tells me that
shmconfig is disabled although it's enabled in the config as you see

Note that you need to set option GrabEventDevice off, otherwise you won't see events on the device while the driver is running.

Confirmed here too.
I first saw it on Zenwalk distribution 6.2 with xorg 1.6.3 (synaptic 1.1.3) and it is still present with Zenwalk 6.4 with xorg 1.7.5 (synaptic 1.2.1).
Also present in other new distribution using xorg 1.7.5 (saw it on crunchbang linux 10 alpha1, unity linux 2010 RC1)
The output of synclient -m 20 shows that x values jumps from ~5900 to
8176 instantly when reaching the right of the touchpad.
Any chances of having this solved in the soon-to-be-released xorg 1.8 ?
thanx,

same here. Pretty annoying.
1.1.0 shows the same coordinate behaviour (i.e. jumps from a little
about 5900-6000 straight to 8176 (stays at that value, even when you
move further to the right) but: It didn't move the cursor. No jumping
cursor. This is far more usable.
Maybe the touchpad is physically divided into two areas..

Proposed fix
I have the same problem. So I made a little change to synaptics.c that seems to fix the problem.
Basically, what I do is fix hw->x to a maximum of param->right_edge when calculating delta x (on ComputeDelta(...)). So, it shouldn't mess with other parts of the driver, and anyway hw->x shouldn't be higher than RightEdge at that point of the code.
The modification is working great in my laptop, but i didn't try on other ones. If someone like to try it, I leave you the patch here. If this breaks something else, I would be glad to refix it (if I can, of course).
By the way, if the fix it's too dirty, the problem seems to reside on the fact that some touchpads' hardware 'x' jumps from around 5900 to exactly 8176 and back , close to their right edge. So maybe a better solution is to keep watch of the 8176 value.

I'm using your patch on Debian Squeeze, and it seems to be working perfectly.
Thanks.

Martín J. Di Liscia,
thank you very much!
I had the same problem with my Asus F3JC notebook. This patch really
helped me. The only thing is that when my finger slides from the
"normal" zone of the touchpad to the scrolling zone, Y coordinate is
still working when I'm sliding up or down.
Please let me know how can I help you to make this patch a part of the
driver, so many people will be happy with that without manual patching?
Should I vote somewhere or stuff like that?

I don't know if I'm understanding you well. But if I'm, that's how I felt was natural. I mean, when you slide past the right edge, is like staying on the border of the normal pad area, so it should keep processing the vertical slide.
Anyway, the two posible behaviors could be configured via a new variable handled from synclient. But that should be a design desicion from the mantainers of the driver.
About making this patch permanent part of the driver, sincerely it's my
first patch commitment, so I have no idea how to do it. I was hoping
that Hutterer saw the patch and do it himself. But yes, I would also
like it, I would't want to apply it to every new version by myself.

how does this patch work for you? It clips the coordinates into the ones
announced by the kernel so that right edge should just be clipped back.

That fixes the jumping problem, but it messes two other things. Now my pad doesn't work on the whole area (left edge principally, now have a inactive gap), and the vertical scroll isn't working either (horizontal scroll seems to work fine).
Maybe the kernel announce a smaller area then the real one.
