I encounter this occasionally on 14.10 and a Thinkpad S1 Yoga. I sometimes have to reboot three times in a row until I get a login that makes my keyboard and/or mouse begin to function. Putting the laptop into sleep and taking it out sometimes seems to work too. The touchscreen always works, so I can login and run diagnostics with the onboard keyboard if necessary. I also have SSH set up so I can connect from another computer to run diagnostics.
