Thread: CPU speed set on Toshiba Tecra M9 (Intel Core 2 Duo)

hello everyone!

installed xubuntu 12.10 on laptop (toshiba tecra m9). works nice, battery life shorter on installed win xp. tried several ways reduce power consumption (by cpu in case), nothing worked me:

jupiter applett
software able change cpu speed (800 mhz, 1,2 ghz , 1,8 ghz) , more. problem was, jupiter applett caused fs mounted read-only when powered battery. fs correctly mounted while powered ac. strange thing. removed jupiter applett because of problem.
anyway, software has stopped active development, maybe not idea use in in new installations anymore.

cpufrequtils
daemon (cpufreqd) crashes while starting , causes xfce generate problem report. not able use commands included in cpufrequtils.

cpu frequency controll in xfce-starter
starter showing actual frequency, can not changed ("no cpu scaling driver available on system").

have no experiences on topic (i used several linuxes, never before on laptops) , maybe have done terribly wrong. happy if suggestions!

cpu model: intel(r) core(tm)2 duo cpu t7100 @ 1.80ghz

thank you!

cpu scaling worked fine begin with. wouldn't assume cpu blame higher power consumption (could gpu or combination of other things).
