It's set to 'centrino' atm. > If your using the generic acpi, try the driver specific for your > cpu/chipset. If not, try using acpi-cpufreq. Is this more complicated than echoing the appropriate string into that file? I get the following: # echo "acpi-cpufreq" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver bash: /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver: Permission denied And nothing in 'dmesg' telling me what happened. I did make a little bit of progress on this yesterday. I found that if I use the 'conservative' frequency scaler, and renice my various courier processes (I use courier-imap for mail) to 19, it's substantially better. Still far from flawless, but only a stone's throw from tolerable. I might try configuring Evolution to talk directly to the Maildir and see what happens. Thanks for the pointers.
