How to make Lenovo trackpoint work for scrolling
Description
It is said that Lenovo’s trackpoint should enable user scrolling when mouse (touchpad) middle button is pressed (first: press middle button, then use trackpoint!). https://www.youtube.com/watch?v=7H8o_-7bKIU https://www.youtube.com/watch?v=H9ya4dUZfTQ
There are some issues with this feature when working on Debian’s machine: 1, 2, 3, 4, 5, 6, 7
Namely, I couldn’t scroll on my system with the use of trackpoint.
This comment from this thread (4) indicates that you can obtain
scrolling abilities of the touchpad by uninstalling
xserver-xorg-input-synaptics package. And indeed it does!.
Well, you also need to have xserver-xorg-input-libinput package
as it written in another thread.
However, the drawback is that in the same moment I lost the ability to emulate mouse clicks by tapping the touchpad.
The last mentioned link gives hints what files should be edited to
restore aproppriate behaviour, but in debian bullseye it is not
needed. You can bring back this feature by tweaking
system settings:
System settings -> … -> Touchpad -> “Tapping” (Tap to click)
and “Scrolling” -> (Two fingers).
TODO Post scriptum
This problem is still unsolved because it looks like uninstalling
xserver-org-input-synaptics disables the possibility to
manage the behaviour of the touchpad from System settings.
Namely, after setting “Tapping” for clicking like it was described
hgghabove, the functionality does not last between system booting.
“SynPS/2 Synaptics Touchpad” is greyed out.
