Running "sudo libinput measure touch-size" gives, for a single finger, max sizes between 580 (finger tip) and 1900 (when I deliberately put the first phalanx down flat).
"Normal" finger placement size is approx 850 to 950. It seems to detect a palm event above 800, and this reliably reproduces the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1764097 Title: 'Apple touchpad bcm5974' unresponsive after "palm: touch size exceeded" on 'Apple MacBookPro5,4 (mid 2009)' with 1.10.4 (Ubuntu 18.04), worked fine with 1.8.2 (Ubuntu 17.10) To manage notifications about this bug go to: https://bugs.launchpad.net/libinput/+bug/1764097/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
