I'm trying to configure frequency scaling on my IBM T43. I did everything like in the wiki but it's not working as it should !
When I'm on battery, and whatever the gouvernor, the frequency is set to 800 Mhz, the lowest available.
I can't set it manually:
[root@Avalon cpufreq]# cat scaling_max_freq 800000 [root@Avalon cpufreq]# echo -n 1733000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq [root@Avalon cpufreq]# cat scaling_max_freq 800000
When I'm on AC, frequency scaling works well and I can set the highest freq...
How can I fix this ?
do you have cpufreqd running ?
Without evil there can be no good, so it must be good to be evil sometimes...
No, the only running daemon is "cpufreq".

stop cpufreqd if you want to configure it manually.
you can use "cpufreq-set -g <mode>"
also you can use acpi for automatic regulation:
$ cat /etc/acpi/actions/lm_ac_adapter.sh #!/bin/bash if grep -q on-line /proc/acpi/ac_adapter/AC/state then cpufreq-set performance else cpufreq-set ondemand fi
