Not exactly. I can change settings via TDE, but the effect has changed: 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....)

The behaviour of Xorg changed after an update.
Before TDE mouse
acceleration worked as expected, allowing the mouse to slow. After the
update the mouse acceleration cannot be turned off. (No, I won't blame the
fine guys on freedesktop.org for breaking things depending on air pressure
- it's just their job)
OK, but this means that for some mice the controls in TDE have no effect -
correct? I use a Benq mouse I bought in 2006 - seems a great
hardware - never had
problem with acceleration described - even after latest upgrade to buster.
However I have experienced odd things with cheap mouse and stupid KVM
switch - like sticky keys - mouse not moving - strange messages about USB
in the syslog etc.
Never mind - the thing is - the function in TDE should set the acceleration
the way you do it in .xsetting, but I do not see an option to set for
specific hardware.
I would file a request to update this in future major release.
