[synaptics] Mouse pointer occasionally jumps to the bottom-left corner

[zanonmark]

Sometimes the mouse pointer jumps directly to the bottom-left corner of the screen, which results in opening the trash window when clicking.

This seems to be related: https://ubuntu-mate.community/t/mouse-pointer-jumps-on-clicking-touchpad/2932.

Thanks,

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

[Michael Quinlivan (michaelquinlivan)]

Exact same problem occurs for me, with the touchpad, usually when clicking something the pointer shoots to the bottom left corner of the screen. Not every time but intermittently. This is a bug that has existed since 14.04, and I managed to fix it back then, but for the life of me I can't remember how I did it. I think I had to make some adjustments to the synaptic driver config, perhaps even had to recompile something... I've searched to find the solution that I used last time but can't seem to find it now!

[zanonmark (info-marcozanon)]

The problem is still reproducible, even after the BIOS upgrade:

marco@filippo8:~$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
[sudo] password for marco:
1.1.9
03/01/2016

Thanks,
MZ

[zanonmark (info-marcozanon)]

Also I would suggest raising the importance a little, as this bug makes the touchpad pretty unusable...

Thanks,
MZ

[penalvch (penalvch)]

zanonmark, to clarify, did this problem not occur for you personally in a Ubuntu release prior to 16.04?

[zanonmark (info-marcozanon)]

I don't know: prior to 16.04 I used 12.04 which was bug-free, but running on another laptop (no clickpad, only a "classic" touchpad with buttons and touch area).
But I read online that this bug should be dating back to 14.04...

Thanks,
MZ

[penalvch (penalvch)]

zanonmark, to clarify, I'm referring to a past Ubuntu release on the hardware reported about in the Bug Description (not some other hardware, or something someone else said).

Hence, it would be helpful to rule out a regression by testing a live environment from http://releases.ubuntu.com/ .

Could you please advise?

[zanonmark (info-marcozanon)]

I confirm the very same bug also occurs in 12.04 LTS (just downloaded 12.04.5-desktop-amd64 and tested).

Thanks,
MZ

[penalvch (penalvch)]

zanonmark, 12.04.5 is the latest release of Precise. Hence, could you please advise which version of Precise you were using? For example, the kernel version you were using would allow one to clue into which one specifically.

[zanonmark (info-marcozanon)]

Tested with 12.04.5, kernel was "Linux ubuntu 3.13.0-32-generic #57~precise1-Ubuntu SMP Tue Jul 15 03:51:20 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux".

Please let me know if you need further information.

Thanks,
MZ

[penalvch (penalvch)]

zanonmark, to clarify, I was intending to ask which version of Precise you were using when this issue was not reproducible, as you noted in https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1574667/comments/8 . Would you know which specifically?

Despite this, to further narrow this down, could you please test 12.04.0 via http://old-releases.ubuntu.com/releases/ ? If that works, you would want to test the next most recent version until the change point has been identified.

[zanonmark (info-marcozanon)]

Christopher, thanks for your time.

Please disregard comment #8, as I was just making a comparison between two different machines - but probably that only added confusion.

Now, about the machine I reported the bug on:
* 12.04.0, 12.04.1, 12.04.2, 12.04.4: X does not start after boot, not even by 'startx' (I attach /var/log/Xorg.0.log);
* 12.04.3 halts right after boot with a kernel panic ("Kernel panic - not syncing - Attempted to kill init!").

So the first distribution running X is effectively 12.04.5, with the kernel reported above.

Thanks,
MZ

[hugh (syscotia)]

Yes I have the same annoying problem. Until a fix is found is it possible to move the trash can to the desk top.
Hugh

[Dieter Orens (dieterorens)]

I'm experiencing a similar problem on a brand new dell xps 13 with 16.04LTS. Sometimes when typing the focus jumps to the bottom left corner near the trash icon. I've also noticed it jumping to other parts of the screen, but perhaps that's due to the sensitivity of the touchpad, but all in all it makes it pretty annoying when coding.

[Yaron Klein (yaronkle)]

experiencing same problem with my Dell 5510 DE running 4.4.0-45-generic #66~14.04.1-Ubuntu.
Happens once every few minutes.
Very annoying.

[Philipp Hauer (phauer)]

Same trouble on my Lenovo IdeaPad U430 Touch and Ubuntu 16.04 LTS.

[Rik Streefkerk (clotskull)]

Just made an account to confirm I have this bug too because it's pretty frustrating. I'm on Ubuntu 16.04.1 (4.4.0-45-Generic) on an Acer Aspire E5-571.

[swaprava (swaprava-deactivatedaccount)]

I'm using Ubuntu 16.04 on Dell Inspiron -- for me the problem is same but the pointer jumps to the top-right corner and clicks the power button. Did you guys figure out any workaround till the bug is fixed?

[zakarpatska (zakarpatska)]

I'm using Ubuntu 16.04 on a Lenovo Yoga S1 and I have the same problem - cursor randomly jumps to the lower left corner when I left click. It makes the system barely usable witb Ubuntu. The system is dual boot and the touchpad works fine with Windows 10, so I don't think it is a hardware issue.

I've tried every suggestion I could find on the web to resolve this issue, but haven't found anything that actually fixes it.

This is a really frustrating issue and it would be great if it could be resolved. Given how unusable this makes the system, maybe the priority of this issue should set higher?

Thanks.

[Noah Johnson (dogarooski)]

I also have this same problem. My trackpad is unusable. Ubuntu 16.04 LTS, Lenovo IdeaPad Y700.

[Timtro (timtro)]

Just started when I opened my Dell Inspiron P69G today (from sleep). I must have run an update yesterday. (I frequently do.)

[Jeff (jjzone44)]

I can also confirm this happens on a Lenovo X230; when clicking the touchpad, the cursor will sometimes move to the lower left corner. Changing finger pressure in synaptic, turning off tap-to-click does not stop this behavior. Lowering sensitivity to it's lowest setting in Touchpad Properties does not solve it either. It is apparent with any distribution based on Ubuntu 16.04, however the touchpad works fine with Elementary OS, and Fedora 25.

[Peter B. (ussenterprisencc1701)]

I have been experiencing the identical problem on my new Dell XPS 15 touchscreen laptop running Ubuntu 16.04 fully patched. Two problems actually:

(1) touchpad mouse pointer randomly jumps to the bottom left corner, which frustratingly can result in the trash application opening up, and at least having to reset the mouse pinter back to where you need it.

(2) mouse pointer too often also jumps backwards several characters so you wind up typing in the middle of your sentence.

Both of the above problems become frustrating enough that you want to throw the laptop across the room, LOL. It happened to me like 3-4 times just typing this. Windows is also on this computer and has no such issues.

Ubuntu, this has really got to be fixed.

[Peter B. (ussenterprisencc1701)]

PS: I realized I needed to point out corrections to my previous post about my Dell XPS 15 which is running Ubuntu 16.04 LTS, as follows:

(1) touchpad mouse pointer randomly jumps to the bottom left corner, which frustratingly can result in the trash application opening up since one might be trying to click an application, and at least having to move the mouse pointer back to where you need it. (this is not related to touchscreen. this is touchpad issue)

(2) text typing ... too often the position jumps backwards several characters so you wind up typing in the middle of your sentence, and sometimes jumps elsewhere in the text field. Just typing this, it jumped once or twice as I said.

[John (gettokid)]

Hi, I am having the same problem on Thinkpad T460s with my cursor jumping and clicking to the left corner bottom where the Trash Tab opens. It happens when I am using both hands, clicking on my touchpad with my left hand and using my right hand to move the cursor.
I tried Ubuntu 16.04 and 16.10, I tried several upgraded, new driver etc. But the problem occurs always.

[Olaf Waszkewitz (olaf-c)]

It started with the 16.04 upgrade. I noticed that the mouse cursor works a few seconds after login but after my Psensor (temperature display) started up, the mouse cursor jumps. Wonder what library Psensor is using.

[Daniel (dosmasdoscuatro)]

Also happening to me. Just bought an Acer Aspire F with intel i3 core. Installed Ubuntu 16.04 (Dual Boot)
Touch pad works perfectly well with Windows 10 (ouch)
Also I have found impossible to chancge touch pad to left-handed (I know it's another topic, but I have searched TONS of pages and found nothing).
Whatever... the pointer jumping randomly and opening Trash can is certainly a BIG issue. Just because of that I avoid using Ubuntu on that laptop as much as possible.

[Daniel (dosmasdoscuatro)]

Just to add to my previous comment, both things (pointer jumping randomly to the lower left and left-handed touchpad unavailable) happen on the new Acer Aspire whose touchpad doesn't have buttons (or, more precisely, are integrated with the touchpad in a single surface). I have Ubuntu 16.04 on an old Toshiba and that doesn't happen (touchpad with separate buttons).
Again, it does not happen in Windows 10

[Juan Hernández (juanhm)]

For me replacing xserver-xorg-input-synaptics with xserver-xorg-input-libinput made the clickpad (a touchpad without fisical buttons) very usable and without cursor jumps.

By default libinput enables multitouch gestures for scrolling, 2-finger clicks (right button) and 3-finger clicks (middle button) but I think you can adapt the configuration file to enable right button clicks on the clickpad instead of the 2-finger option.

All I had to do was:
sudo apt-get install xserver-xorg-input-libinput
sudo apt-get remove --purge xserver-xorg-input-synaptics

..and reboot

[Philipp Hauer (phauer)]

Juan's fix does the trick for me! Thank you so much!

The only drawback is that I can't inverse the scroll direction with two fingers anymore. Under Settings > Mouse & Touchpad the checkbox "Natural Scrolling" is gone. But I'm just glad that I can now use the touchpad at all.

[Juan Hernández (juanhm)]

Philipp, I'm using Cinnamon instead of Gnome and the option is still present.

Anyway I guess you could try Ubuntu Tweaks to change this property or simply set the option by editing the configuration file installed with the package (I think it should be "/usr/share/X11/xorg.conf.d/90-libinput.conf") and adding the following line inside the "InputClass" section:

   Option "NaturalScrolling" "true"

[Philipp Hauer (phauer)]

Changing the "/usr/share/X11/xorg.conf.d/90-libinput.conf" worked for me! Thanks again, Juan!

[chrissy mcmanus (chrissy-mc-1)]

Juan's fix worked for me.
I find that I cannot slow down the mouse speed through both the system menu and unity-tweaks, but i can get used to it i guess. It has tho given me back middle-mouse-button click emulation by means of using left and right click simultaneously, so this is a win win situation....

[zanonmark (info-marcozanon)]

Thanks Juan, your fix seems to work actually!

I confirm the pointer speed is very high, but a "xinput -set-prop 11 281 -0.5" command solved the issue (281 stands for "libinput Accel Speed" and 11 is the proper device i.e. "DLLC6B2:00 06CB:75BF Touchpad").

Thanks,
MZ

[Juan Hernández (juanhm)]

I think you can also set this property in the configuration file /usr/share/X11/xorg.conf.d/90-libinput.conf:

Option "AccelSpeed" "-0.5"

[Peter B. (ussenterprisencc1701)]

The previously posted Juan workaround also worked for me too on the Dell XPS 15 running Ubuntu 16.04 LTS. Thank you all. :-)

Patch system first, then do the following fixes posted by Juan and others (see previous posts).

sudo apt-get install xserver-xorg-input-libinput
sudo apt-get remove --purge xserver-xorg-input-synaptics

vim /usr/share/X11/xorg.conf.d/90-libinput.conf

  InputClass #Inside the sections for pointer and touchpad
    Option "NaturalScrolling" "true" #note I used this
    Option "AccelSpeed" "-0.5" #note I tried this - made mouse too slow - commented it.

Reboot.

[Samuel Holmes (samuel-holmes6)]

Hi,

I was having the same issue, but the fix suggested by Juan Hernandez at #32 seems to have worked!

I had to install xserver-xorg-core before I could install xserver-xorg-input-libinput, but it seems to work now!

[tinga (tinga90)]

I also confirm the bug on my DELL Inspiron 7537 and Ubuntu 16.04.2 LTS with a fresh install.
Even after all updates, the problem is still here: the cursor jumps randomly during selection, dragging and other clickpad operations. It literally drives me crazy.

Applied all suggestions posted above, with attention to the reply #32 and other indications find on the web: https://forum.siduction.org/index.php?topic=6180.0

The clickpad feeling is still really bad, inaccurate, not suitable for daily use.
PLEASE FIX IT, a pointer like this makes system unusable

[zanonmark (info-marcozanon)]

@tinga: What exactly didn't work for you?
For me, replacing synaptics with libinput (as in #32) did the trick.

Then I also had to write a little bash script to reduce the speed:

#!/bin/sh
xinput -set-prop 11 281 -0.75
exit 0

or you could set this in 90-libinput.conf, as in #38 and #39.

[dlotton (yellow56)]

Same problem on new XPS 13 9360 with Mint Mate 18.1 Serena 64-bit

[tinga (tinga90)]

@zanonmark
- two finger scroll loses the focus and start selecting/clicking in the scroll surface randomly.
- tap to click non recognized in the title bar.
- sometimes dragging or moving selected content makes the cursor jump, generating an
unintentional pressing/clicking randomly

[Robert Joynt (robertjjoynt)]

I have this problem using the clickpad for an HP Omen 15-at201tx running Ubuntu 16.10. Changing the driver from synaptics to libinput did fix the problem, but I like coasting (kinetic scrolling) so I would like to stay with the synaptics driver. The problem doesn't occur in Windows 10.

[Luca Ciavatta (cialu)]

Same issue on Acer Aspire ES1-111M-C1LE with Ubuntu 16.10 (before) and 17.04 (now).

[Robert Joynt (robertjjoynt)]

I have upgraded to Ubuntu 17.04. The problem doesn't occur any more. I'm using the synaptics driver. The clickpad is working fine now.

[zanonmark (info-marcozanon)]

Robert, thanks for letting us know.

[ihendley (imran-hendley)]

I have this problem on my Dell XPS 15 9560 running Ubuntu 17.04. It occurs specifically when I am moving the pointer with one finger and I click with another finger before lifting my original finger. The only workaround is to only have one finger on the touchpad at a time, which is very slow-going. Replacing xserver-xorg-input-synaptics with xserver-xorg-input-libinput as suggested results in my keyboard not working and does not even seem to fix the problem.

[Michael Verrilli (msv-8)]

I have this exact issue on a Dell Precision 5510. I tried the libinput workaround along with modifying the settings as discussed above... and it mostly works except now I cannot use right click. On this touchpad, the click is by pushing the touchpad itself, not separate buttons.

[Michael Verrilli (msv-8)]

I figured out the issue with my right-click. Just documenting in case anyone else does the libinput swap. It defaulted my settings with Two-finger emulation enabled. Just disabled it an all is good. Thanks @juanhm.

[Evan Ney (evny24)]

Same problem on my thinkpad t440s. I think I've pin-pointed what's going on. Tapping in two separate locations on the trackpad very quickly in succession registers as if you have put your finger down in the first location and swiped it to the second location, thus causing the cursor to move as if you swiped rapidly. I tied messing with all the synaptics settings but no luck. Juans fix works, but you lose a lot of the nice feel of synaptics settings.

[Peter (p-templar)]

The solution proposed by Juan Hernandez (message 32) worked for me. I am running Xubuntu 16.04 on a Dell Inspiron 3542. I finally decided to look for a fix after successfully using a wireless mouse for some time. I did not have to modify /usr/share/X11/xorg.conf.d/90-libinput.conf as some others did.

[Dave (dawidatmobica)]

I had similar problem with cursor jumping randomly on my Dell E5570 with Ubuntu 16.04, but the solution posted her by Juan Hernandez did not help.
I found out that my Track Stick (stored in the middle of my keyboard) is source of the problem. When I disabled it the problem just disappeared.
I guess the problem is with the driver for the track stick as it worked just OK on Windows.

The following link was very helpful:
https://cederlys.wordpress.com/2010/07/13/disabling-the-track-stick-in-ubuntu/#comment-694

I used the following to list the input devices:
xinput list

and to disable the track stick:
xinput -set-prop "AlpsPS/2 ALPS DualPoint Stick" "Device Enabled" 0

Hovewer after reboot the trackpad is back on, so I added the above command to "Startup Applicationns"

Regards

[Angelos Pikoulas (agelos-pikoulas)]

I had the same problem with a Dell Inspiron 7720 and a Lenovo 710S (both booting the same external SSD with Kubuntu 16.04) - so annoying! It was solved with #32, so easily! Many kudos!

I just can't believe this solution is yet to be included in all distros if it works so well! Stupid bugs like this give Linux a bad name for no good reason!

[ChrisC (ccurrier99)]

#32 seems to be the best work around. Thanks Juan! Mint 18.2 (New Build).

[Omk (ossi-viljakainen)]

I have this same issue on Dell XPS 13.
Mouse pointer jumps intermittently to the lower left corner. When typing, the cursor occasionally jumps to the middle of the sentence. And occasionally the mouse pointer just freezes, and does not move at all using the trackpad, unless I simultaneously click and hold down the button, while dragging the pointer around with the trackpad. Sometimes Alt+TAB to another program may revive the mouse, and at others, have to close the lid, suspend and awake to re-activate the mouse. Very annoying, making the laptop practically unusable.

[Jens Forker (jens-forkers)]

Lenovo Ideapad 2 13 (2 in 1 convertible, touchscreen)
Ubuntu 18.04 (+ 17.10, + 16.04)

even after installing 18.04 and the latest updates on Jan 2nd 2018 the following feature persists:
a few times a week the cursor goes nuts - it looks like it's jumping to the lower left corner (gnome desktop), clicking, and thereby calling the program tiles onto the screen. Then clicking again making the tiles disappear, clicking again calling the tiles,..... sometimes with quite a high frequency. This turns the laptop pretty much useless because it's "trapped" in this state. Whatever you try it's always calling the tiles :-(
This happens even if I'm not touching the notebook at all!!
I couldn't find anything to influence this behavior. Even after rebooting it continues! But at some random point in time the jumping stops and the notebook can be used as before and works like a charm - until the jumping starts again.

Because I used the fix from https://askubuntu.com/users/750621/keringar (Thank you!!) the on screen keyboard is not coming any more. But for me it looks that the root cause of the osk popping up is the cursor jump/click.
As I have tried very many of the suggestions above and in other forums I tend to believe that it's really a bug somewhere deep inside (graphic driver?) as this bug appeared with Gnome and also Unity desktop.

Solving this for good would REALLY promote the use of Ubuntu :-)

[jpvrlaone (jpv4433)]

I had the same problem on my desktop with Ubuntu 16.04 but #32 worked for me. It too was driving me crazy.

[Justin (jtbr)]

I have this problem on a Dell XPS 15 laptop touchpad running Linux Mint 18.3 based upon Ubuntu 16.04. This actually defaults to libinput, and that's where I first encountered the issue. So I tried synaptic to see if it would go away (it did not), which led me to this bug. So for me it happens with both drivers, it's just worse under synaptic. With libinput, it doesn't jump as far across the screen. But it does jump, under the scenario described in #52 -- you're moving the mouse with one finger to where you want to click, and you click with the other finger. But at that moment the pointer jumps in the direction of the other pointer (for right-handed people clicking with their pointer finger, this is to the bottom left).

Sadly, these are touchpads without dedicated buttons, but being used by users who are used to having and using dedicated buttons. In either case, it's quite frustrating. And it does not occur under windows, so it isn't a hardware-only issue.

[zanonmark (info-marcozanon)]

Seems solved on Ubuntu 18.04.

[Nick (morrownr)]

I am going to disagree with #62. I am running Lubuntu 18.04 fully updated as of the date of this message.

My system is a Dell Optiplex 9020. I have tested with a Logitech M325 wireless mouse, a Dell usb mouse and an old hp PS/2 mouse (the Optiplex 9020 is a modern system but does indeed have PS/2 ports.)

Symptoms: Periodically I see the mouse cursor run uncommanded to the upper left corner of the screen and it takes a while to get back down to where it should be. This happens with all 3 of the mice previously mentioned.

I intend to try to the solution in #32.

[einar.kristian (einar-kristian)]

Running 18.04.2 and the mouse started to jump to top right corner on screen 1 out of 2 a few days ago. Tried #32, but ...libinput-all was also removed and after reboot, no response from mouse or keyboard. Started in protected mode and reinstalled libinput. Still same problem. I've tried Logitech wireless, Bluetooth and wired mouse. When running sudo cat /dev/input mice, there is continuous input, even when the mouse has jumped to the top right corner. I've also changed batteries in the Logitech mouse. I certainly would like this problem to be solved. For now, I'll continue to search for solutions on the web.

[einar.kristian (einar-kristian)]

Ref #64, it was the external switch. I restarted it and everything works!

[Mauricio Chavarriaga (mchavarriagam)]

Thanks Juan! #32 fixed the issue for me. ASUS VivoBook S14 (S430F) running Ubuntu 18.04.4 LTS. This issue was driving me crazy, it was impossible (and quite dangerous) trying to work while fighting the pointer.

[Timo Aaltonen (tjaalton)]

the synaptics driver is unmaintained upstream, so I'd suggest anyone suffering from this to uninstall it and verify that -libinput is installed

[Chris N (vollucris-deactivatedaccount)]

This is not fixed!!!
I've been having this issue since I got my Dell Latitude E7470 Ultrabook.
I have Ubuntu 18.04.4 installed and with each new version of Ubuntu I hoped this will be fixed. It's not!
My installation doesn't even use synaptics, it's using libinput so, #32 doesn't bring anything new.
I want to mention that the exact same thing is happening even if I use a wireless mouse. And it isn't that the cursor jumps to the bottom left hand side of the screen but it sticks there for quite a few seconds until I manage to pull it back up.
WTH is this issue and why can't anyone figure it out?

Please help! I am sick of this thing!

[Daniel van Vugt (vanvugt)]

Chris N,

It sounds like you are experiencing a different issue so please open a new bug by running:

I'm experiencing the same problem as Chris also on a Dell Latitude E7470 Ultrabook but with Linux-Mint.
