Or, more clearly execute this as root: # echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor You can check which scaling-governors are available on your kernel/system with this: $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governor Cheers, Niels > chkconfig --level 2345 cpuspeed off > (also file not found) > > /usr/bin/cpufreq-selector -g performance > (from package gnome-applets, requires GNOME and I'm running in text mode only) > > I also found this unanswered related message > http://lists.fedoraproject.org/pipermail/arm/2010-December/000791.html > > So, how do I disable CPU frequency scaling in Fedora ARM from the console? > > Thanks > -- > -- > Danilo Câmara > _______________________________________________ > arm mailing list > arm@xxxxxxxxxxxxxxxxxxxxxxx > https://admin.fedoraproject.org/mailman/listinfo/arm _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
