d) option a) + since the above changelog entry seems related to
syndaemon usage, change syndaemon to set CircularScrolling=0 and
{Vert,Horiz}ScrollDelta=0 as well as TouchpadOff=2 (maybe adding
options to choose what to disable and what not)
The attached (trivial) patch resumes the old behaviour associated with
TouchpadOff=3 (option c) but I wrote it before thinking of option (d)
that I actually prefer.
Peter, your thoughts about it?
Kind regards.
