*Rubbing Google's prejudice out of eyes* I knew I had read something about cpufrequency somewhere, but couldn't find it anymore. The script and the bit about NOT setting the performance_governor as default, were the two things that solved it. I am using the conservative governor and it is working just as I hoped it would. Slow when possibe, fast when required.

Why do you think you need those (I'm curious) ?
Just trying to find my way :-) By the way, the cpufrequtils package is the one that gave the odd values, which do not fit my processor. Therefore I cannot recommend it. I have no idea what it can do anyway, besides showing info from /proc and /sys. A few tips for the hint: Advise people to load the various modules first, or bash will complain about the echo command when you run the script. If the readers are using modules of course. Without the cpufreq_ondemand module loaded: ./cpufreq ondemand Enabling ondemand cpu frequency ./cpufreq: line 9: echo: write error: Invalid argument ignoring niceness for ondemand ./cpufreq: line 13: /sys/boot/devices/system/cpu0/cpufreq/ondemand/ignore_nice: Onbekend bestand of map I changed the script a bit to include the conservative module and changed demand into ondemand. I also added a status line. There is also a typo in it, where 'speed' is written as 'spead'. I am not using powernowd and I don't think I will need it, so I cannot comment on the last part of the hint. Thanks a lot!
