Description darkbasic 2011-07-15 10:53:11 UTC
I recently switched from an HD3870 to an HD5870, before dynpm did work flawlessly (expect of a bit o flickering), but now it doesn't work anymore (it keeps 'high' and does not switch to the lower power states). Instead 'low' power profile does work even better than the 3870, it goes from 70 to 45°C instead of 55°C.

linux-3.0.0-rc3, mesa git master, libdrm git master, fx86-video-ati git master, xorg-server 1.10.3

Let me know which kind of information do you need.

Does anything change if you use kernel >= 3.11? See http://www.botchco.com/agd5f/?p=57
