I should give some explanation about this parameter. It enables an older power management mechanism in the kernel that gives better performance with my GPU than the newer one. With radeon.dpm=1 I can use a script in /etc/local.d/ that contains this line: echo "performance" > /sys/class/drm/card0/device/power_dpm_state Positive effect is, that desktop/window operations and also video playback are much smoother. Negative side effect is, that the power consumption of my GPU and also its temperature is a bit higher than with the default settings. If I don't use radeon.dpm=1 it is also possible to manually set a GPU scheduler: echo "profile" > /sys/class/drm/card0/device/power_method echo "high" > /sys/class/drm/card0/device/power_profile But as I already mentioned, performance isn't as good as with the older power management. However I checked this out many months ago. Maybe it isn't relevant anymore. -- Regards wabe
