Public bug reported:
On installing ubuntu 20.04 LTS on Apple MacBook Pro 16 inch, 2019, on
choosing ubuntu from the startup manager, a blank screen is obtained. If
we boot the kernels using rEFInd, then they get booted easily. Also, I
am not able to even boot into an Impish Indri ISO. A discussion
T2 Macs are not the only Macs that have USB internal trackpads. See
bcm5974.c which is shipped with noble. The fix in upstream libinput
applies to them as well.

Public bug reported:
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.
