Public bug reported:
I am using Jaunty 64 bit on my Notebook and have seen, that the default
gevoernor is now set to performance.
Because I wan't to run the ondemand governor i tryed to change the governor via
the gonme applet, but this seems to have no effect. So I tryed 'sudo
cpufreq-selector -g ondemand', but I haven't recognized any change again. Even
a process with a nice of 19 causes the processor to run in full speed.
In Intrepid I used the ondemand governor too and the cpu was not speeded up by
a process with a nice value of 19. So I think these two ways didn't change the
governor.
So I tryed (with the hint in bug 344252 ) to compile the kernel with the
ondemand governor set as default:
grep -i default_gov /boot/config-2.6.28.9
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
But this seems to havn't changed anything too. I noticed, that a nice 19
process causes full speed too.
So it seems that I can't change the governor on my notebook.
