Thread: Disable automated cpu frequency scaling?

hi,

there lots of existing posts this. i've read many (all?) of them, , tried suggestions find. none of solutions in threads work.

ubuntu 9.04 jaunty jackalope doesn't scale cpu frequency correctly. set lowest setting--800 mhz (intel 2.27 ghz core2 duo in dell latitude e6400). trying change command-line or cpu frequency scaling monitor 2.26.1 has no effect. reason, want manually scale cpu frequency or disable remain @ max.

in case, 99.999% of time cpu freq. scaling isn't necessary since i'm running on ac power, , cpu core temps cool (40 degree c or under). yet unbuntu insists on running @ 800 mhz. happens cold boot resume suspend , hibernate.

disabling speedstep in bios forces cpu cores operate @ lowest frequency. none of config file mucking around i've done has helped.

governor settings (conservative, ondemand, performance, powersave) appear "stick" in cpu frequency scaling monitor, there no actual change in performance when selected. selecting of actual frequencies (800 mhz, 1.60 ghz, 2.27 ghz) has no effect--the monitor still shows 800 mhz.

can do? @ wits' end.

thank you,
