CTRL-ALT-F1 will not take to to a log-in screen. I have to manually shut down the system with the power button. Doesn't anyone have an idea as to what to do to troubleshoot this problem? This is on my Ubuntu 14.04.1 LTS system running kernel 3.13.0-45-generic #74-Ubuntu SMP Tue Jan 13 19:36:28 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux. I still would like to know what info is needed as per the status on this report.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
