Do not require password in cpufreqselector

From http://linux.aldeby.org/do-not-require-the-password-for-cpu-frequency-scaling-in-ubuntu-karmic-9-10.html

In Ubuntu Karmic 9.10 the frequency scaling GNOME applet always requires a password in order to allow you to change CPU frequency or governor. This is due to policykit profiles enforcing some more strict security.

Helas these profiles are not editable trough the applet in System -> Administration -> Authorisation.

Fortunately, as always in linux this can be achieved by simply editing a text file:

gksudo gedit /usr/share/polkit-1/actions/org.gnome.cpufreqselector.policy

locate the following lines

要調整 CPU 頻率需要權限。  no auth_admin_keep   

and replace the highlighted text

要調整 CPU 頻率需要權限。  no yes   

This change is unfortunately to be applied every time policykit gets updated.

The launchpad bug is #455694
