I've tried to boot with a keylogger loaded on rc.local and as an option on lightdm to see if the keys are captured but I got no input from the moment I leave GRUB and the kernel start to load until the infamous 15 seconds after LighDM is loaded. Since the issue seems to be strongly related to i8042, I've tested some kernel options:
i8042.direct - Put keyboard port into non-translated mode i8042.dumbkbd - Pretend that controller can only read data from keyboard and cannot control its state (Don't attempt to blink the leds) i8042.noaux - Don't check for auxiliary (== mouse) port i8042.noloop - Disable the AUX Loopback command while probing for the AUX port i8042.nomux - Don't check presence of an active multiplexing controller i8042.nopnp - Don't use ACPIPnP / PnPBIOS to discover KBD/AUX controllers i8042.reset - Reset the controller during init and cleanup Again without any tangible results. I've extracted from dmesg all the information from i8042 (with 'i8042.debug' option on GRUB). ** Attachment added: "i8042.debug.txt" https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1596200/+attachment/4692296/+files/i8042.debug.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xinput in Ubuntu. https://bugs.launchpad.net/bugs/1596200 Title: Ubuntu 16.04: unresponsive keyboard (15 sec) after grub Status in kbd package in Ubuntu: New Status in udev package in Ubuntu: New Status in xinput package in Ubuntu: New Bug description: I've upgraded my notebook with an SSD. All works fine and I can reach the login in less than 10 seconds. Problem is I can't use the internal keyboard (perfectly working on grub) for at least 10-15 seconds, then it starts to working just fine. The touchpad and capacitive buttons are working without issues. Luckily I have a second HDD on my machine and I've made some tests with the old mechanical drive, with this unit I can input my password on LightDM without any delay. The issue is not (only) related to Xorg or LightDM, because starting in recovery mode shown the same issue with both disks: if I use an external keyboard (a Logitech k400r in my case) I have no issue at all on both login and recovery mode. Seems kdb needs some time to be up and running.
