# # Configuration file for Laptop Mode Tools module cpufreq. # # For more information, consult the laptop-mode.conf(8) manual page. # ############################################################################### # CPU frequency scaling and throttling # ------------------------------------ # # Laptop mode tools can automatically adjust your kernel CPU frequency # settings. This includes upper and lower limits and scaling governors. # There is also support for CPU throttling, on systems that don't support # frequency scaling. # # This feature only works on 2.6 kernels. # # # IMPORTANT: In versions 1.36 and earlier, these settings were included in the # main laptop-mode.conf configuration file. If they are still present, they # overrule the settings in this file. To fix this, simply delete the settings # from the main config file. # ############################################################################### # Enable debug mode for this module # Set to 1 if you want to debug this module DEBUG=0 # # Should laptop mode tools control the CPU frequency settings? # # Set to 0 to disable CONTROL_CPU_FREQUENCY="0" # # Legal values are "slowest" for the slowest speed that your # CPU is able to operate at, "fastest" for the fastest speed, # "medium" for some value in the middle, or any value listed in # /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies. # The "governor" can be any governor installed on your system, this usually # includes "ondemand", "conservative", and "performance". The # "IGNORE_NICE_LOAD" setting specifies that background programs that have # a low priority ("nice level") should not cause the CPU frequency to # be increased.
