    New bug, since clockgating works now for my rs482, dynamicPM is able to lower my core to 71MHz when i'm on battery mode, BUT when i put the AC back, the clock stays at 71Mhz instead of going up to 400 and plus MHz.

    So, dynamic can lower but can't restore the default state.
    im using rovclock to restore the clock back to 4xxMhz, till a fix emerges.

    best regards.

      This one ?

      It looks like there are already new packages for Jaunty

        Thats the one thanks!!! acording to xorgontheedge, the combined ppas + compiled drm should give dri2 to radeon 2xx up to 5xx.

        anyone did this test already? does it work? i would like to know if it works before trashing my system

        UPDATE: after i compared the packages from the PPAs i come to the conclusion that jaunty already have more recent packages.
        so the only thing missing would be drm (which i can compile myself)? is the radeon 4xx dri2 support already in trunk?

          The DynamicPM option only changes the power state when the screens are blank (DPMS active). If you are getting changes in power states on AC/DC changes, then something else is messing with the chip, perhaps the bios.

            I believe you but if its so, the bios wasn't changing anything before i activated the clockgating. anyway, i can confirm the same behaviour when the dpms is activated (back to 71Mhz), doesn't restore the default when the screen comes back.

            best regards and keep up the good work

              Should be fixed now in git.

                Hum.. :P well.. now it stays at 4xxMhz even with dpms more on.

                also, now when i go into batery mode it doesnt go down to 71Mhz.

                Strange indeed. any more fixes?

                best regards

                PS. yes i know, my card is evil :P

                  Same issue like groo_pcd, now it's not going down, also for my rV280 it is now slightly overclocked (from 238.5 MHz to 240.75 MHz)

                    It only goes into a low power state when DPMS is active, nothing to do with the AC/DC state. to test:

                    sleep 5; xset dpms force off

                    the chip will drop into a low power state. When you move the mouse, or hit the keyboard, it will switch back up to the higher power state.

                      ok, i can confirm it does work, strange it doesnt change frequency when dpms is called with vbetool, like i was doing. sorry, my mistake.

                      [email protected]:~$ sleep 5; xset dpms force off; sudo sh -c 'rovclock -i'

                      The only thing strange is that, before the last fix, when i was on batery mode, the clock WAS INDEED changing. any explanation on that one? just curious? i know it must be the bios, but it wasnt changing anything before toay rs482 clockgating fix, and i have this laptop for 3 years
