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. ** Affects: xorg (Ubuntu) Importance: Undecided Status: New ** Tags: dpm kernel radeon ubuntu xorg xorg-server ** Description changed: 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.
