My HP Pavillion Dv5 1004nr worked great with Ubuntu up until 11.04. Now, ever since Unity desktop environment the display has been sporadic at best. I was told that the video driver bugs (known and largely ignored) were fixed for the ATI raedon card in my laptop with 13.04. So I installed it. 13.04 doesn't even detect the display. Boots to black screen every time now. Is there ever going to be a fix for the AMD architecture with ATI raedon chipsets? do the developers even care? this has been an issue for years, and no sign of a fix in sight....
