KPowerSave can't set CPU frequency policy
Hi guys,
I have a problems with setting cpu frequency using kpowersave 0.7.3 (I'm using KDE 3.5.10 under openSUSE 11.4). kpowersave displays cpu frequencies properly, but is unable to detect the current frequency policy/governor (it says it's unknown) and can't set the cpu speed - the option is available but attempt to use it results in a warning that the given policy cannot be set. I can successfully set the cpu governor using commands like powersave or cpufreq-set, it's just that kpowersave can't do it. |
Problem solved. Here's the solution in case any of you encounters the same problem. Everything seems to have been caused by Polkit/Hal interaction. In /etc/Polkit/Polkit.conf I added:
<match action="org.freedesktop.hal.power-management.cpufreq"> <return result="yes"/> </match> You man add <match user="yourusername"></match> to restrict access to particular user. Previously I had problems with mounting removable devices - this also required extending Polkit policies. You may also use polkit-actions to list available Polkit entries. |
