Cursor is over excited and jittering all the time

[Wise Melon]

I have found that since installing this package that (unlike before the installation) my cursor seems over excited all the time as even when I just have my finger on it but am not moving it really at all it is jumping up and down very quickly and always jittering (this is very annoying if one is trying to go down a page by pulling the side-bar down with the cursor for it jumps up and down most of the time and shakes and when try to be move still). I also (no matter how I adjust the speed in the gnome-control-center) can't seem to get it to be the right speed, it's either too fast or too slow (it was just the right speed and non of the jittering before installing this package, now with this package it seems practically impossible to get it right) and no matter the speed setting, it is always jittering about, maybe there needs to be some way of also changing touchpad sensitivity or something because this cursor is just crazy.

It also seems as though I am not the only one with these problems: https://bugs.launchpad.net/ubuntu-gnome/+bug/1586657/comments/8

Status changed to 'Confirmed' because the bug affects multiple users.

[Jeremy Bícha (jbicha)]

See https://bugs.freedesktop.org/95290 which might give you some ideas about how to report this bug upstream and maybe work around it until an updated package with a fix is released.

[Jeremy Bícha (jbicha)]

Reassigning to the libinput package based on the similar bug report.

[Wise Melon (wise-melon-deactivatedaccount)]

Ok, I've linked my upstream bug report, I hope that I have done everything correctly.

[Jeremy Bícha (jbicha)]

Thank you for reporting the bug upstream and linking it here.

[Wise Melon (wise-melon-deactivatedaccount)]

Should I do the same with my other bugs reports on the xserver-xorg-input-libinput package? And if so, do I just report them all against this upstream package or...?

[Alberto Salvia Novella (es20490446e)]

@ Nikita

You shall report upstream if the bug is not Ubuntu specific, but could affect any operating system using the software.

[Wise Melon (wise-melon-deactivatedaccount)]

@Albert,

Yes, I know, it's just that the others are reported under xserver-xorg-input-libinput like this one was originally, so I reported this one under the libinput upstream package, but I don't know what to do for the xserver-xorg-input-libinput ones, is it just the same package? I mean, what is the difference between these two packages? Should I report all the other xserver-xorg-input-libinput bugs under libinput upstream because that is the only package upstream with any related name?

[Wise Melon (wise-melon-deactivatedaccount)]

This bug has been fixed upstream: https://bugs.freedesktop.org/show_bug.cgi?id=96290#c6

Using 17.10
My Elantech mousepad on Gigabyte laptop is nearly unusable.
Over sensitive. Move and it suddenly decides I tapped and start selecting text, or it clicks when I did not tap.
Trying to find where to configure the sensitivity reveals lots of dead programs (gpointing-device-settings, Synaptiks) etc. Nowhere a simple answer on what config file to edit and what the parameters do.

[Daniel van Vugt (vanvugt)]

Fix released, per comment #10. That fix would have gone into Ubuntu quite some time ago. In fact we're now working the opposite problem caused by that fix -- sensitivity too low for many people.

Unless Nikita thinks this bug is still open, everyone else please report new bugs of your own. Such issues are very specific to a touchpad model, and even to the user.
