I have tried everything to stop the screen from going black on this distro. I see online that it is a MAJOR BUG that many people are experiencing. I want to strangle the programmer who engineered this fault. (Just kidding...not really!). I have no idea if it is the Power Manager that is responsible...but because of the structure of your Bug Reporting (which I really hate)...I had to choose something!
Under what context does the screen go black? Is it during boot, or only when idle? Could it be the screensaver or the system going to sleep or hibernate?
