Hi,
I was eager to try out the new linux kernel (2.6.36) and the latest oss ati driver for my onboard "Mobility Radeon HD 4650", but am actually disappointed. Yes, it works! That's one major thing, but the power management seems to utterly fail.
I've had to set the power profile to:
echo mid > /sys/class/drm/card0/device/power_profile
note: changing mid to "low" works but doesn't seem to affect the fan speed.
to get some fan speed down, but it still works like this:
fans off for ~30 seconds
fans fully or nearly fully on for ~5 minutes
then off again
then fully or nearly fully on again for ~5 minutes..
That is highly distracting!
I tried the "dynpm" power_method, but that gives me flickering and i'm not even on a dualscreen setup.
So, is there a better way to have fan auto fan control? I'm using ArchLinux and it's fully up to date
I was kinda expecting the fan control would "work" for pre 2.6.36 kernels and would certainly work with 2.6.36... Guess i was wrong since i notice no difference at all between 2.6.35 and 2.6.36
Regards,
Mark
