Public bug reported:
Hello, I want to report that i have some issue with my screen. I tried a
lot of thinks to repair it but it does not want go. I mean, I have
problem with flickering on the screen. Sometimes it's just a part of the
screen flickering, at other times it is flickering of the entire screen
so I cannot do normal work, and at other times there is no flickering. I
reinstalled Ubuntu 3 or 4 times but still have the same problem. Of
course, I did not have this problem for about two months of using Ubuntu
but this problem showed up suddenly, afer one day.
