Just installed Linux Mint 17.3 with KDE on HP probook 6470B. Installation went well, the system said it was restarting - DVD was ejected and system seemed to shut down but it didn't. I tried Ctrl+Alt+Del but got message from root@mint that it was starting emergency keypress handling, then stopping emergency keypress handling, then starting store sound card state, and lastly stopping store sound card state.
I can type on the screen but there's no terminal. How do I recover from this state?
