I have a laptop with 4670hd, I trid today last git radeon drivers with last xorg and last kernel. It works like a charm but it overheats a lot ! I also get 10 -15 degrees more even on idle ...
And all of this even if I have tweaked my xorg and put the "low" profile for power management. I think these radeon drivers are just not ready for laptops. My battery time is half with radeon drivers compared to catalyst..
- check to make sure the /sys paths mentioned below are present and tweak the commands if necessary
- echo "profile" to /sys/class/drm/card0/device/power_method
- echo "low" or "mid" to /sys/class/drm/card0/device/power_profile
same for me.. the clock rates is low according to "low profile" but it overheats still a lot..!
When you guys talk about "overheating", do you actually mean the machine shuts down because the temp exceeds a threshold, or is the laptop simply hotter but otherwise functional?
no shutdown. but not really functionnal for a laptop which has (with FOSS driver) half time battery and 10-15 degrees Celcius more on idle than Catalyst driver :/
