Xecure
@rokytnji & @skidoo: sorry for the somewhat late reply, but I was busy trying to figure out settings and combinations thereof. I 1st set the vertical scrolling in one of the system files (can’t remember exactly which one) to zero, which seemed to help a bit, but no completely.
You probably edited /etc/X11/xorg.conf.d/synaptics.conf (or something similar like 50-synaptics.conf), and modified the Option “VertScroll” “1” to “0”. To disable it. In some trackpads, it is “DeltaVertScroll”, and instead of decreasing the number, one needs to increase it to make scrolling slower.
So I subsequently followed @rokytnji‘s suggestion, and 1st set the threshold to 60 (was 1), but that did not do it, then set the acceleration to zero (was 2) and that seems to have done the trick.
Checking just in case: when applying those changes, did you check “Enable mouse configuration on startup” to on? You probably did, but I wanted to be sure.
I was too quick off the mark: none of my actions have resolved the issue.
For the trackpad problem, I started xev on my laptop to see what keys appeared when using the scroll part of the trackpad. I should have guessed: Button4 and Button5 (mouse wheel).
So, after spending some time researching the trackpad problem, I propose two “solutions”:
A) “Difficulty: Easy”- Reduce mouse-wheel sensitivity with imwheel (worked on my trackpad, found solution on mx wiki: http://mxlinux.org/wiki/hardware/mouse-tweaks/, I set it to “1” instead of “3” and followed the suggestion in the comment on how to start imwheel only stopping button4 and button5).
'imwheel --kil --buttons "4 5"
To make it permamnent you must add the same command to the startup file for your selected window manager (I am sure you will find an answer in the forum for whatever WM you are using).
B) “Difficulty: Medium” Modify how the trackpad “works” with xinput. (Worked on my laptop)
Install xinput. Once installed, open a terminal and execute:
xinput list
See what id the touchpad has. In my case, it is “ETPS/2 Elantech Touchpad, id=13”
Use the list-props option
xinput list-props device-id
where device-id is the one you have observed in xinput list before. This will display a list of all the different behaviors that can be modified for this device. For me it was:
xinput list-props 13
Each device might be different, so pay attention to what you want to modify. In my case, I wanted to modify “Synaptics Edge Scrolling” to disable scrolling, which was initially set to “1, 0, 1”
xinput set-prop 13 “Synaptics Edge Scrolling” 0 0 1
If instead of disabling it, I want to increase the “scrolling distance” (reduce scrolling sensitivity) I would change “Synaptics Scrolling Distance· (initially set to 58, 58)
xinput set-prop 13 “Synaptics Scrolling Distance” 200 200
This made my trackpad scrolling veeeery slow (less sensitive)
(more info (but not exactly the same) here: http://help.ubuntu.com/community/SynapticsTouchpad)
I have played a bit with xinput settings when figuring out how my touchscreen worked, but I really don’t know enough. I recommend you copy all the list-props output and save it to a file so you can reset any changed options incase something goes wrong.
