Ide o to ze pri ovladaci fglrx som pouzival na podtaktovanie nastroj aticonfig.
aticonfig --list-powerstates
core/mem [flags]
-----------------
* 1: 128/135 MHz [low voltage]
2: 392/252 MHz
3: 479/378 MHz [default state]
aticonfig --set-powerstate=1
ovsem v novom ubuntu 9.04 to uz nebude mozne. Jediny nastroj co som nasiel je rovclock ovsem ten mi nespravne detekuje frekvenciu.
$ sudo rovclock -i

Otazka znie. Ake nebezpecne by bolo aj za takych podmienok pokusit sa podtaktovat kartu na tych 128/135 MHz. Cize
sudo rovclock -c 128 -m 135
Graficka karta ATI Mobility x2300/M64.
V sk/cz forach som o tom vela nenasiel a en mi nejde az tak aby som spravne rozpoznal rizika s tym spojene.

Rovnako aj v bete ubuntu 9.04 sa este neobjavil neslobodny ovladac. Aj ked bolo by pekne ak by som sa mylil. :-(
Este mozem dolnit ze to chcem podtaktovat kvoli teplote na najnizsej frekvencii mam teplotu nizsiu asi o 10 st. C.
sudo rovclock -itak ti to v tom poslednom riadku vypise skutocnu frekvenciu alebo tak ako mne uplne ine hodnoty.rovclock -i
