On the other hand the kernel has advanced enough now to offer power management |
33 |
for ATI cards. I've set this up for my Mobility Radeon HD 4670: |
34 |
|
35 |
cat /etc/local.d/set_radeon_power_profile.start |
36 |
echo auto > /sys/class/drm/card0/device/power_profile |
37 |
|
38 |
and it stopped the cooling fan from working all the time irrespective of the |
39 |
load. This also makes the battery last longer. |
