Note that Ubuntu doesn't ship a kernel that supports T2 Macs yet. I
think 6.15 is where most of that got upstreamed. So this isn't a
priority for Noble updates right now.

Title:
Trackpad on T2 Macs over aggressive in palm rejection
Status in libinput package in Ubuntu:
Fix Released
Status in libinput source package in Noble:
Triaged
Status in libinput source package in Oracular:
Fix Released
Status in libinput source package in Plucky:
Fix Released
Bug description:
The trackpad on T2 Macs needs to increase its AttrPalmSizeThreshold in
libinput quirks to 1600 in order to have proper palm rejection. The
current value of 800 results in normal finger taps being rejected and
the trackpad being aggressive in terms of palm rejection.
Fortunately, this issue has already been fixed in upstream libinput here:
https://gitlab.freedesktop.org/libinput/libinput/-/commit/ed9570df6065d2f29e0ef7946505f90167588906
I've also attached that patch with this report.
