SUMMARY
 I upgrade to linux-image-5.4.0-9-generic linux-modules-5.4.0-9-generic linux-modules-extra-5.4.0-9-generic and it requires a restart. Afterwards the backlight? is turn off/ the screen is very dim. I couldn't find a solution to re-brighten the screen.

1. upgrade through the terminal to new linux image
