Originally posted by kraftman View PostI've found I have to echo [something] to /sys/class/drm/card0/device/power_profile. The problem is there's no power_profile. It seems it works for other people.
Now, look if drm and radeon modules are loaded:
$ lsmod | grep radeon
if not:
# modprobe radeon
Then:
$ dmesg | grep -i drm
Paste the output on the forum, for all to study.
I've been using the new power management for some time now, and always the files:
/sys/class/drm/card0/device/power_method
/sys/class/drm/card0/device/power_profile
have been created, and correctly worked.
Like this:
# echo profile > /sys/class/drm/card0/device/power_method
# echo low > /sys/class/drm/card0/device/power_profile
Finally, sorry if I've rehashed basic things; they could be useful to somebody, someday. ;-)

Now, look if drm and radeon modules are loaded:
$ lsmod | grep radeon
lsmod |grep radeon
radeon 916632 2
ttm 68317 1 radeon
drm_kms_helper 32776 1 radeon
drm 207342 4 radeon,ttm,drm_kms_helper
i2c_algo_bit 6222 1 radeon
