I am having the same problem with hardy on amd64. When I am plugged in, I get 2333MHz (which is right). When I am not plugged in, my laptop always gets the lowest available frequency (1000MHz in my case).
cpufreq-selector -f 2333000 will occasionally work for me, but usually only lasts less than a second, even with the cpu freq. governor set to cpufreq_userspace. I tried the workaround in http://ubuntuforums.org/showthread.php?t=760282, but it doesn't work for me. This is a really annoying bug, makes it impossible to watch x264 videos unless I am plugged in (among other things). -- Low throttling always active : machine very slow https://bugs.launchpad.net/bugs/199391 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
