Not exactly. I can change settings via TDE, but the

Previously I could disable acceleration for my touchpoint, nowadays that
does not work any more. For a touchpoint the model is e.g.:
dx_screen = dx_touchpoint * (a_driver + a_TDE) + dx_touchpoint ^ (b_driver
+ b_TDE)
Now "a_driver" and "b_driver" have changed (bigger as before) and
the
accepted values for "a_TDE" and "b_TDE" have change to > 0. So
that's a
problem TDE won't be able to fix :(
The negative acceleration value for libinput that I came up with is just a
hotfix/hack, it does not restore old behaviour but is better than what I
had without.
Oh, and it only affects the touchpoint (have I written "touchpad" earlier?
ooops....)

Can also be the result of the underlying libinput/xinput changing. libinput
for Wayland is appearing more and more there are some growing pains. Here are
a few references for mouse acceleration and libinput (and xinput and xset)
