Identical issue here on MacBook Pro (13-inch, Mid 2009) aka model MacBookPro5,5 using Ubuntu 18.04 final release.
I can also attest that this issue does not only affect Ubuntu. Fedora 27 exhibits the same symptoms for me. Do not know if it is related, but simply resting one finger on the touchpad spams evtest with a load of ABS_MT_WIDTH_MAJOR, ABS_MT_WIDTH_MINOR and ABS_PRESSURE events. It seems like it somehow 'chokes' up due to this. Trying to click-and-drag is a 100% reliable way to make things lock up. -- 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' is temporarily unresponsive after a few seconds of continuous input in 'Apple MacBookPro5,4 (mid 2009)' after upgrading to 18.04 Beta 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1764097/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
