I had Ubuntu 14.04 and have done a clean install of 16.04. I had problems on 14.04 and on upgrade all problems were solved except ubuntu freezing.
Now it is freezing occasionally and only a force shutdown works. I have tried magic sysreq method, ctrl+alt+del, alt+f2, nothing can solve it. What should I do?
ctrl+alt+n
, where n is a number from 1-6. – saga Jan 24 '17 at 08:54
