[Bug 936552] Re: MacBookAir 4, 1 trackpad does not work with evdev/multitouch driver
It's not really a separate touchpad, it's a /dev/input/mouseX device registered by the mousedev driver for the same touchpad, kind of a legacy mouse device for applications that need that sort of thing. It's there in the good and bad case, and X seems to be (correctly) ignoring it. I think you may be onto something with the keyboard remove being related. I don't know what's going on, and I don't see it on my MBA 4,1, but dmesg does show usbhid devices disappearing and reappearing about 18 seconds after boot. Actually it looks like the usbhid module is unloaded and reloaded. If I rmmod then insmod usbhid on my machine my touchpad stops working until I restart X. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Spoke too soon. I just did a reboot and had no trackpad. Still looks like lightdm just starts a tiny bit too soon, before some bits of the hardware are initialized.

[Bug 936552] Re: MacBookAir 4, 1 trackpad does not work with evdev/multitouch driver
Well I've at least found a workaround. I added 'udevadm settle' right before the 'exec lightdm' in /etc/init/lightdm.conf. As long as that is in place, I do not experience this issue. So, I think this is an issue with boot speed. My machine has almost nothing installed beyond the default, and boots from grub - lightdm in about 5 - 8 seconds. That might explain why you don't see it Seth if you have more things starting at bootup, as that may be enough to delay X long enough for udev to be available. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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/xorg/+bug/936552/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 936552] Re: MacBookAir 4, 1 trackpad does not work with evdev/multitouch driver
Update.. so now everything works fine with the synaptics driver, no boot to 3.2.1 or 3.2.6 required. I suspect this was an xorg problem all along. If I remove xserver-xorg-input-synaptics then the trackpad stops working (and oddly enough, the keyboard becomes really hard to use if X is running.. very hard to describe, but keypresses are lost). In my experience, the synaptics driver is really bad at palm detection, so I am not really happy about having to use it, but at this point, its my only option. Redirecting to xorg.
