Ahojte,

před pár dny jsem přeinstaloval svůj (neaktulizovaný) Arch linux. Samozřejmě, že s novou instalací se mi nahrály do systému aktuální verze aplikací a tudíž i kernelu. Bohužel se mi v novém archu nedaří "srazit" spotřebu i přesto, že jsem systém nakonfiguroval stejně, jako ten starý. Dřív jsem v idle stavu měl 11-13 W a notebook vydržel 4 a půl hodiny, teď se nemohu dostat pod 17 W a můj ntb vydrží tak 2 hoďky v idle stavu. Ve "starém" archu bylo jádro 2.6.37 a v novém je 2.6.37-ARCH #1 Také ovladače grafické karty byli starší a nyní jsou 8.82.8. Podezřívám ovladače na grafickou kartu, že nefunguje regulace výkonu (podtaktování zřejmě funguje, ale proud grafickou kartou teče pořád maximální, pokud se nepletu - viz. aticonfig --odgc)

Notebook: HP ProBook 4520s Procesor: Intel(R) Core(TM) i3 CPU M 37 Grafická karta: ATI Mobility Radeon HD 5000 Series Wifi: RaLink RT3090

Nenapadá někoho, kde by mohl být problém ?

Díky

[cheaf2@cheaf-ntb ~]$ aticonfig --odgc

	Default Adapter - ATI Mobility Radeon HD 5400 Series 
								Core (MHz)    Memory (MHz)
			Current Clocks :    157           200
				Current Peak :    750           800
	Configurable Peak Range : [400-750]     [500-800]
					GPU load :    0%

Obávám se, že ta vysoká spotřeba je způsobená ne-omezováním průtoku proudu graf. kartou - ale možná, že se pletu, ale nevím přoč tam nemůže být current peak max: 400
