I'm having the same issue on my Lenovo T430s using Ubuntu 16.04.3, except that my internal keyboard works just fine, it's my external USB keyboard that has the issue.
Same symptoms though; as soon as lightdm starts up (after having entered the password via plymouth to decrypt and mount the hard-drive), the external keyboard is completely unresponsive for about 15 seconds, after which the keyboard starts to work and I can enter my credentials. I'll try to reproduce what Frederico had already tested to see if I can resolve the above issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1599306 Title: [HP Pavilion dv2910us Entertainment Notebook PC] i8042 need to start early after grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1599306/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
