Hello, I hope you are well
I just entered the world of Django and wanted to ask what is the right source
And the second question is that I just installed the Ubuntu operating system (version 20.04) and after installing I saw that in some places the screen turns on and off very quickly
For example, when I watch a full screen movie on YouTube, the screen turns on and off very quickly every few seconds.
I have searched a lot but i can’t find a correct answer
thank you
