I hope everyone doing well in this difficult time. Actually, I am having a screen flickering issue on my laptop with newly installed ubuntu 18.04. My laptop model is Dell Inspiron 15 5000 with Nvidia graphics. The flickering is not so intense but it is happening continuously which is just boring to work. Initially, I had ubuntu installed on my laptop and thought this flickering may be the cause of the wrong installation of operating system. That is why I have made a fresh installation of ubuntu 18.04 but the same thing is happening again. Honestly speaking, I am not an expert on Linux but can do general stuff. I can not understand what causes the problem. I had tried to resolve it by googling but unable to do so. Graphics on my laptop...

I will appreciate any suggestions regarding this issue. Please let me know if you need more info.
