**Note this tutorial assumes you are using PM-Utils as compared to laptop-mode-tools. If you haven't installed laptop-mode-tools manually then your fine.
1. Copy the power saving scripts from '/usr/lib/pm-utils/power.d/' to '/etc/pm/power.d/'
2. Run my script to change all of the 'false' values to 'disabled' and all of the 'true' values to 'true|false' thus disabling the system to go to performance mode and always staying in power save mode.
3. Enjoy a cooler laptop!
To copy the power saving scripts you type:
Code: Select all
sudo cp -r /usr/lib/pm-utils/power.d/* /etc/pm/power.d/
The reason we do this is because the directory /etc/pm/power.d is for us as users to add scripts or modify them to our liking. The original directory is used for a backup in case the system cannot use our modified scripts.
You could change these scripts manually but why not use a script to do it instead? All my script does is look for "false)" and change is to "disabled)" and then change the "true)" to "true|false)". The reason behind this is each script is run with the parameter 'script true' or 'script false' when the system goes from power saving mode or to performance mode. We don't want the system to go to performance mode so we can disable the 'script false' statement by replacing 'disabled' into the statement.
Code: Select all
#--- Purpose is to modify pm-utils scripts to never go into
#--- performance mode and always stay in powersave mode
# if [find 'false']
# change to 'disabled'
# if [find 'true']
# change to 'true|false'
for file in $(find $folder -name "*")
sed -i s/"[^|]false)"/" disabled)"/g $file
sed -i s/"true)"/"true|false)"/g $file
Enjoy a cooler laptop! Also if you use KDE I've noticed a significant difference in performance with KDE 4.8.
