Is this only when you are surfing the web and video viewing? Is it most prevalent on flash sites (Youtube, etc)?Or can it happen while the computer is idle?
I have Ubuntu 11.04 (natty).
I have read 'Screen goes blank when VLC is playing video'
My question is similar, but also I have this problem when viewing a video on youtube.
I am not quite clear about the meaning of 'computer idle'. Is it considered idle only when the keyboard or mouse is not being used?
I used squid proxy for internet sharing. I blocked youtube and flash video in config. But want to allow specific video on youtube.
