    dynpm doesn't work that well for me either with mobility 5830. I get screen blackouts when clocking and it doesn't go as low as on windows.

    On windows the driver lowers engine to 100 and mem to 200 when there's no activity.

    On linux it just lowers the engine clock to 400 from 500 and memory stays at 800. So i have to manually set it to low profile to get 100/200.

    Hmm there doesn't even seem to be a "mid" profile for my card. only default, low, auto, high. I am using xorg-edgers, r600g, and 2.6.37 kernel.

    echoing mid does nothing, echoing default, low, high all work.

    Any plans on when power can be controlled without having debug features in the kernel?

    I also have annoying flickering when dynpm is enabled on kubuntu maverick, xorg-edgers and a 2.6.37-rc5 kernel on my laptop with a HD 5650 Mobility. It only happens when I do something, when it's reclocking maybe?

    Profiles is the only viable option for me, since dynpm still causes my laptop (RS480) to freeze.

    I did try the profiles but they made stuff like scrolling in firefox laggy for me, but granted this was a while ago before a lot of the recent optimizations and scrolling has gotten a lot better so I should probably try it again. Dynamic would definitely be ideal though.

    Same here with my hd2600, and the power management doesn't even seem to bring temps down much yet, so right now I have to stick with fglrx so I don't burn my house down.

    This is a funny one. Actually, the screen flickering I mentioned when doing stuff on the terminal only happens when using Yakuake, which is the terminal I use for mundane things. When using urxvt or xterm everything is normal.

    ???

    Well, something odd I noticed is that now I don't get much flickering when doing regular GUI stuff, like browsing the web or so. I could live with that. But when stuff is displayed on a terminal it's a lot worse. So, for instance, doing "top -d 0.1" (just to get something going on) the screen flickers every 2-3 seconds or so. That means that sometimes I'll open a terminal and will get annoyed with those glitches when I start typing something.
