Compared to hid-multitouch, the RMI stack seems to have completely broken
palm rejection and introduced some random jumpiness during fine pointing
motions. I don't know if these issues are caused by the above errors or
are a separate issue.
Just to confirm: I noticed "jumpiness during fine pointing motions" as
well since switching to 4.11-rc.
Thanks both of you for the reports.
Andrew, Jiri, I think switching everybody to rmi4-core was maybe not the
best move. Could we add a module parameter somewhere to force switching
back to hid-multitouch? (Or the other way around more likely).
We might need to have users testing rmi4-core and report libinput bugs,
but introducing such regressions for everybody is IMO not the right way.
Note that I do not see any differences besides bug fixes when switching
from PS/2 to RMI4-core on my Lenovo T450s, so maybe the hid-multitouch
capable firmware does some more filtering (the Lenovos are not using HID
for the touchpads).
---@benjamin: Just wondering: Could that have something to do with theThis has nothing to do. ps2->rmi is not used at all by hid-rmi as the
ps2->rmi handover? I noticed that patches to improve things in this area
are still circulating, which lead me to wonder if that might have
anything to do with this. But it's just a wild guess.
enumeration is done in the ACPI. The series you are mentioning are for
touchpads that do not enumerate. Once enumerated (either through PS/2 or
HID), the code should be the same.
Cheers,

The affected machine is an XPS 13 9343 running Fedora 25 with 4.11-rc1Same setup here. In case it matters: I'm running Gnome-Shell in Wayland
and libinput 1.6.3-3.fc25 (latest in F25).

Ciao, Thorsten
P.S.: I fixed the model number in above quotes from Cameron to avoid
confusion (he has a 9343, and not a 9443, as initially stated; see a
different mail in this thread for details)
