It appears this is related to sudo permissions... on Ubuntu Server, I can not do this via sudo, but if I su to root, I am able to:
leo@ubuntu:~$ sudo echo "2601000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed; echo $? -bash: /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed: Permission denied 1 leo@ubuntu:/sys/devices/system/cpu/cpu0/cpufreq$ sudo su [sudo] password for leo: root@ubuntu:/sys/devices/system/cpu/cpu0/cpufreq# echo "userspace" >> scaling_governor root@ubuntu:/sys/devices/system/cpu/cpu0/cpufreq# cat scaling_governor userspace root@ubuntu:/sys/devices/system/cpu/cpu0/cpufreq# echo "2601000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed; echo $? 0 How would one go about adding the ability to echo things into this via sudo? :( this breaks some tests -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1035050 Title: Unable to set scaling frequency on cpu with Precise server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1035050/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
