My problem was experienced by several Ubuntu users a few years ago.

The difference is that I'm running the latest Ubuntu operating system (19.10).[![enter image description here](https://i.stack.imgur.com/XH9NG.png)](https://i.stack.imgur.com/XH9NG.png) 

I ran with Ubuntu 18.04 Disco Dingo about 1.5 yrs ago; and upgraded to Ubuntu 19.04 about 6 months ago. Never had this problem with both O/S versions using the same laptop (Lenovo ideapad 320).

The problem started about a month ago.

What is the solution to my problem ?
