Bottom lower left in taskbar / panel open that and under preferences I believe look for software & updates and open it and then set it up as below with one exception.I must say - that the "black screen" happened after Linux/lubuntu auto update it self to a newer version Lubuntu 18.10 with Linux 4.18.0-14 (from Linux 4.18.0-13).
Where it says "Notify me of a new Ubuntu version" change that to Never.
