[Solved] Problems with scrolling using touchpad after update



Hi, I’m new to this forum :slight_smile:

I’m using Manjaro for a while, and didn’t run into any major problems that weren’t already solved online.

My current problem that I can’t seem to find help for online, appeared right after I did the last update. Before the update the scrolling functionality on my touchpad was flawless. Now - it’s more like some percent chance that it will recognize the two finger scrolling as a scroll gesture, and most of the time the mouse is only moving. So while I’m trying to initiate the scrolling, I’m just trying that with two fingers repeatedly until it happens. Some times though, it starts right away, but other times it takes more than 10 trials.

I tried installing xf86-input-synaptics, but it makes my mouse acceleration and speed really bad and far from precise, and I’ll have to manually edit config files for the natural scroll direction.

I’m asking f you know what created this bug for me, or how to solve it. It’s not that broken like this, but I’m losing my patience.


Below is the dump from running the - inxi -Fxzc0 command.

[Stable Update] 2017-04-02 - Mesa-Stack, Kernels, Plasma, Firefox

Now, after update, I have the same problem. Need help.


As a temporary workaround you can try

  1. remove synaptics driver and downgrade libinput.

  2. downgrade the kernel.

Only try 2 if 1 doesn’t work. If 2 works, try different kernels to see if one of them works better.

You can also rollback the update that caused the issue, if you have trouble finding the cause and need a more working environment to dissect the problem.

But in general, my advice is: find the package that caused the issue and downgrade it. Update again later to see if the issue has been resolved.


Hey, it seems I got the same problem after update. Excellent, that’ll help in troupleshooting…

The culprit is libinput package. Just donwgrade it with

donwgrade libinput

If you don’t have donwgrade, install it with

sudo pacman -Sy donwgrade

You should report this issue so it gets fixed on the next update. Someone will probably report it, because it seems to consistently happen with update.


Wonderful. Your solution worked for me. Thanks.

If downgrade libinput also worked for you, please set this topic to solved.

Unfortunately my screen’s brightness Fn keys on my notebook don’t work anymore after update. But I’m sure I’ll find
a solution with forum search. It’s curious, because the other Fn keys for volume control a keyboard backlight work fine.


Found a solution. Now, my brightness Fn keys, work fine:


Thanks, downgrading libinput fixed the issue.

I guess I’ll keep this old version for a while until it gets fixed or something…
