Also, the problem is not specific to any user. It randomly affects any of the users of the machine. At that moment only that user is affected.
Next time it may affect the same user or another. We believe that it may affect several users at a time, if we keep the machine running until problem affects a second user. In practice, however, users have some work to do, so we reboot the machine to let them continue their work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1779667 Title: Unlocking existing session yields black screen.
