I use laptop-mode-tools for power management on my laptop and for the life of my I cannot find where to configure the CPU frequency limits. When I'm on battery it sets the maximum limit, regardless of governor or my manual intervention, to 1Ghz. Normally this is good but there are some situations where I want the full 2.4Ghz out of my CPU. However, if I set this manually through the Unity applet or via cpufreq-selector
to higher than 1Ghz it is completely ignored while on battery.
This is extremely annoying. I've grep'ed everything in /etc looking for configuration options. The only thing I've found is in /etc/laptop-mode/laptop-mode.conf where the limits are simply fastest
, slowest
etc. I've found references to several other files, none of which exist, I guess because cpufreqd
is not installed. I tried installing that package but the daemon immediately crashed so I guess there's a conflict between that and the laptopmode tools manager. Any ideas?
