Mouse cursor would move however the keyboard was totally inactive. I've since downgraded to 3.13.0-44-generic #73-Ubuntu SMP. This issue is so intermittent that I fear if I ran any kernel debugging I'd have gigabytes of data.</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>
