Kubuntu 12.10 KDE 4.9.5
While playing a movie on my computer, after ten minuted the screen goes black until I move the mouse. The second time it happened at 16 minutes. To try to avert the problem I opened System Settings>Power Management and unchecked everything in the hope that it would stop. Since it did not happen with the same time separation, I am confused about the cause.
I seem to remember help on this problem previously, but I cannot find the solution and do not remember how to fix the problem. I do not need help concerving energy and would like my computer to work without having to restore by making a move with my mouse. TIA for any help you may provide.
