What does: source /usr/bin/cpufreq-detect.sh echo $MODULE report on your system? Try to load the $MODULE via 'modprobe $MODULE' then, does cpufreq-info report anything then? > BTW, anybody know the 'conservative' governor? Yes. ;) But I usually prefer the ondemand governor. Check /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor for current settings as soon as cpufreq is working. regards, -mika- -- http://grml.org/ # Linux for texttool-users and sysadmins http://wiki.grml.org/ # share your knowledge http://grml.supersized.org/ # the grml development weblog #grml @ irc.freenode.org # meet us on irc
