Public bug reported:
When you try to enable 'radeon.dpm=1' parameter into ubuntu linux kernel
it makes strange things with display server like: corrupt graphics,
screen blinks and other crazy stuff. However, if you try to watch a
movie, xorg crashes and you have to restart your computer because you
can't run any action, i mean, the screen frezes.
In the other hand, i actually don't know if xorg-server crashes because
of 'radeon.dpm=1', or it's radeon driver itself which is crashing xorg-
server using 'radeon.dpm=1" parameter.
I'm using a AMD Radeon HD of the 6800 series in Ubuntu Trusty Tahr
14.04.
