changing Frequency Scaling Monitor? in chrome os

Gnimmelf · 03-25-2011, 10:07 AM

hi there
i`ve been using this command

Code:
sudo gedit /etc/init.d/ondemand
(in linux mint and ubuntu)

to open the textfile where i could change the Frequency Scaling Monitor to "performance".

i`ve tried the same in chrome os but it wont allow me. (Chrome OS Linux 1.0.648 RC)

is it possible? could somebody help?

thanks in advance. kindly gnimmelf

Chrome OS is a very minimal and highly customized Linux system, commands that you would use on a normal Linux OS will do no good. In this case, you can't make changes to /etc, gedit is not available in Chrome OS, and I wouldn't even be so sure that frequency scaling is supported yet.

You could do a custom build of Chrome OS to address all of these issues, but that is probably a lot more work than you are willing to do for this.

Its a lot more work than im able to do!

im yust a rookie who found some usefull comands.
its a shame though frequency scaling isnt supported, my mint 9 is realy fast, the fastest i could find, using this option (changing the monitor to performance).
Ive benched it with hardinfo and nothing "comes close", and i would really like to see how fast Chrome OS could get.

thanks for the reply though! nice clean and informational.

i installed cpufreq and used this command.

Code:

sudo cpufreq-set --governor ondemand

changing ondemand to performance. and it worked on the first cpu but not the second, and not on restart.
then someone on another forum gave me these

Code:

cpufreq-set --cpu0 --governor ondemand

Code:

cpufreq-set --cpu1 --governor ondemand

they gave folowing error

PHP Code:

Hi there

i figured it out!

CODE: SELECT ALL
sudo cpufreq-set -c 0 -g performance
sudo cpufreq-set -c 1 -g performance

this did the trick.....
but not on restart? any ideas?
