hi. ich habe mein ubuntu 10.04 letztens neu aufgesetzt, da das alte 11.10 so vollgemüllt war, dass es kaum noch zu gebrauchen war. Neben den üblichen add-ins für mein thinkpad x60 (sowie hdaps & lüftersteuerung) habe ich mich endlich auch mal dem stromverbauch zugewandt. nun nutze ich den Ubuntu, mit Linux 2.6.32-36-generic-tp mit der pcie_aspm=force option, habe tlp installiert und habe den phc patch im kernel genutzt ( dieser bringt die cpu auf stabile 11:30 8:15 6:1 clocks runter). trotzdem zieht mein system noch über min. 12 watt (es sind ein paar usb sachen am rechner... klar ziehen die ihre 3 watt) aber mein hauptproblem ist, dass sobald ich powertop 1.97 öffne schnell der stromverbrauch in die höhe, innerhalb von 5 sec. ist er auf min. 20 watt und ich befürchte dass sich dieses auch anderweitig ereignen könnte ich nutze metacity als desktop manager, habe gelesen, der soll sparsam sein. habt ihr erfahrungen woran es liegen könnte ? ich würde mich sehr über stablie 10 watt freuen, dann bringt der 9-zeller akku auch endlich das was er unter windooofs könenn soll...
der x60 nutzt den intel gm945 chip. welcher von den x-updates treiber nutzt... kann das evlt damit zusammnhängen ?
kann es sich evtl um ein konflikt zwischen tlp und dem gnome-power-manager handeln ? habe schonmal versucht zu messen nachdem ich den gekillt hatte. kein unterschied !
falls ihr weitere daten braucht, meldet euch einfach. ich füge schonmal die conf des tlp bei und nen powertop auszug.
