i have Dell inspiron 3542 laptop .
I was using Ubuntu 16.04.1 from last 4 months and it was working normal but by mistake i deleted Ubuntu partition in windows.
After reinstalling Ubuntu 16.04 again my screen start flickering. I have also tried Ubuntu 16.10 but it was also flickering. Even it flick while installing.Tried different kernel but no success.
When i start moving cursor then screen become more brighter and when i left cursor then it become little darker.
Also screen working normally in windows 10 and Ubuntu 12.04.
