I've just encountered this bug in an up-to-date hardy on my MacBook Pro.
I have tried a few things to try and fix it, but I haven't had any luck.
In my xorg.conf, I've switched it to use the event protocol with the
specific device.
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device"
"/dev/input/by-id/usb-Apple_Computer_Apple_Internal_Keyboard_._Trackpad-event-mouse"
Option "Protocol" "event"
It works great on first bootup, but after a resume, I get this in the
Xorg.0.log:
(EE) xf86OpenSerial: Cannot open device /dev/input/by-id/usb-
Apple_Computer_Apple_Internal_Keyboard_._Trackpad-event-mouse
Has anybody else found this problem? Maybe it's MacBook Pro specific?
The resume ordering of kernel modules?
