OK, fixed for 2.6.20-12 and possibly earlier: usbhid complaining about pb_fnmode option not being supported. That option was set in /etc/modprobe.d/touchpad (by me, not by the system) so that pressing F1 gave F1 instead of <lower_brightness>. By default you need to do FN+F1.
I think this is new, as usbhid didn't complain before, and now when I boot into the new kernel I have to use FN to get at the F-* keys. I can live with that, since I've got wireless back. Will look for a new way to get function behaviour back. Fix in my case: remove /etc/modprobe.d/touchpad -- No keyboard input in X nor shell https://launchpad.net/bugs/88748 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
