The other thing I notice is that there's a separate touchpad device that's registered between the first and second detections of the keyboard:

But I guess something about the remove/re-add of the keyboard leaves the touchpad in an inconsistent state. So it's either a kernel driver or an X driver issue... udev is just the messenger here, passing through the add/remove shown it by the kernel. -- 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/936552 Title: MacBookAir 4,1 trackpad does not work with evdev/multitouch driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/936552/+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
