But, naturally, I'm making assumptions about your particular setup.

My understanding of the state of affairs is that while strictly a Wayland project (and hence categorized as such in their Bugzilla), libinput may also be used under Xorg with a separate wrapper driver.

I know you tried :). I'm not assigning blame here as I would've done the same based on the documentation available. According to my earlier comments, I ran into the same issue on Fedora, reported it here https://bugzilla.redhat.com/show_bug.cgi?id=1575260 and got excellent support. One of the libinput devs caught it and helped me out. I would suggest stepping through the same process as I did by following the comments on that report, but filing a bug directly at https://bugs.freedesktop.org/enter_bug.cgi?product=wayland=libinput as it is an upstream issue. On Ubuntu, however, you might have to install some of the libinput debugging tools separately. If we're lucky, and as our hardware is really similar, the same palm detection threshold might work for you as well like this: # MacBookPro5,4 (Mid 2009) libinput:name:bcm5974:dmi:*:svnAppleInc.:pnMacBookPro5,4:* LIBINPUT_ATTR_PALM_SIZE_THRESHOLD=1000 ** Bug watch added: Red Hat Bugzilla #1575260 https://bugzilla.redhat.com/show_bug.cgi?id=1575260 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in 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 ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

The instructions the original reporter links to, for debugging touchpad issues in Ubuntu, is outdated. The way it seems to me, 18.04 Bionic Beaver uses the libinput drivers instead of synaptics by default. At least that is the case on the LiveCD. Therefore, this bug report is linked to the wrong component - understandable due to misleading documentation. Furthermore, my initial analysis of the root cause was way off. The real issue is that the palm detection threshold for this particular model is set too low in libinput. Consequently, spurious palm detection events make the touchpad temporarily unresponsive. I've submitted a patch for this quirk upstream. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in 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 ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Deceivingly similar issue, and one that I also encountered, in Fedora here: https://ask.fedoraproject.org/en/question/120258/macbook-touchpad- becomes-unresponsive/ And a fix here: https://bodhi.fedoraproject.org/updates/FEDORA-2018-abb147f32e It would be nice to have this resolved as it pretty much renders Ubuntu unusable in affected Macbooks.

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-X, which is subscribed to xserver-xorg-input-synaptics in 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 ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
