Well, I'm doing random stuff like `[root at t480s device]# echo 5 > resync_time` since I have no idea what I am doing and It's not helping..

Sorry, I'm not a Gnome user. I one of those suckless linux users (lusers) who try to remove every gnome or kde app on their machine. Is there no cli tool I can effectively jam my trackpoint with?

It doesn't seem to account for the Y access. In my case here: https://s.natalian.org/2018-03-21/libinput.txt X axis is probably 25? and y is .. er.. 13? So how would LIBINPUT_ATTR_TRACKPOINT_RANGE look?

That hwdb configuration syntax looks a bit daunting.

Kind regards,
