When i use opensource driver for ATI card - notebook fan always spinning
and themperature of outgoing from fan air is very high, even when I set
/sys/class/drm/card0/device/power_profile to low and cpu mode to
powersave. With proprietary drivers (fglrx) I set video card performance
to "ondemand" (I forgot the exact name of this mode in ATI control
center) and cpu mode to ondemand, and notebook isn`t hot, fans not
spinning (if I not start flash, games or some similar app with high cpu
load). So with fglrx I can use notebook from battery 1,5-2 hours and
it`s not hot, but with opensource driver battery of notebook is down in
50 minutes, fan is olways on, it noise is loud, and notebook is very
hot.
