This is a Lemur Ultra running 14.04. I don't know when exactly this started happening, but not too long ago. My guess is that it was a recent kernel update that did this. Anyway, it seems like suspend has stopped working properly. When I try to wake up, I get the prompt for password, but I cannot type it in since the keyboard appears to be "disconnected" (has no effect). It appears to happen if I choose suspend from the gear menu (and use the power button to wake) or if I close the cover and open it to wake. The only way I know to recover is to do a long press on the power button to force a reboot. Has anyone else seen this? Is there a fix?
