Powersave CPU governor instead of performance

Feedback Documentation
1

When typing in terminal :

cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

I’ve noticed that Clear Linux uses the powersave CPU governor instead of performance which is supposed to be the default.

I didn’t change anything on my computer.

Is it a change made by the Clear Linux developpers ?

The CPU governor is back to performance in Clear Linux 35390

It’s back to powersave in Clear Linux 35860

Are you running Clear on a laptop ?

Yes I’m using a laptop. But I’ve been using Clear Linux for a year and it always has been on performance.

Except now.

There was a change in clr-power-tweaks that went in at the end of October to select the performance setting for servers, and powersave for everything else.
I don’t know why you saw it flip back to performance in December, although there was a brief period a couple of months ago when we had to fix a crashing bug in clr-power-tweaks.
If you want to permanently switch to performance despite the CPU identified, you can check out the man page

man 5 clr-power-tweaks

or just copy and paste the following line into /etc/clr-power-tweaks.conf

/sys/devices/system/cpu/cpu*/cpufreq/scaling_governor performance

and that should ensure it is set the way you want after any reboots or updates.

I’ve just created the /etc/clr-power-tweaks.conf file and added /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor performance inside and rebooted but the powersave CPU governor remains

This is what happens when I don’t test this out for myself :slight_smile: You may have found a bug.

Looks like this has been fixed in 36020 (or if not then, in 36030). @erik Could you update to the latest and retry?

Thanks,
Chris

I’ve upgraded to 36030, rebooted and the CPU governor is now performance like I wanted.

Thanks @pixelgeek .

Good to hear - thanks for the feedback

i created a systemd oneshot module to run at boot time which calls a bash script that runs…

for file in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do echo "performance" > $file; done

… to not have to think about what the default being set is.

I’m having trouble switching from performance to powersave on an AMD mini-pc.

by replacing performance to powersave it should use powersave instead

Hi!

Any way to have a UI toggle to switch governors? Like Fedora do with power-profile-daemon?

I tested the gnome-shell extension called Frequency Boost Switch, which can modify the governor when selecting or not the Intel Turbo Boost, but the toggle do not changes anything, unfortunately.

we don’t have a UI for this.

Our policy is to use powersave for laptops and similar, but performance for servers and workstations (things with a power cord)

Thanks.

Sometimes, a laptop also have a power cord :wink:!

With this shell script, I was able to have my Framework 13 laptop automatically change between performance and powersave modes when on battery. YMMV.

#!/bin/sh

# Switch CPU governor to performance when on AC power
mkdir /usr/local/bin
tee /usr/local/bin/set-perf-mode.sh << 'EOF'
#!/bin/sh

if [ "$1" = true ]; then
    echo "/sys/devices/system/cpu/cpu*/cpufreq/scaling_governor performance" | tee /etc/clr-power-tweaks.conf
elif [ "$1" = false ]; then
    echo "/sys/devices/system/cpu/cpu*/cpufreq/scaling_governor powersave" | tee /etc/clr-power-tweaks.conf
else
    rm -f /etc/clr-power-tweaks.conf
fi

Thanks for sharing your script!

Another option : i use the gnome shell extension named “Custom Command Toggle” to create two new toggles in the Gnome menu : one to launch Powertop and to deactivate Turbo Boost in order to gain some watts when my battery is empty, and antoher one to seelct Powersave or Performance.

It works well with a native look. Of course, you have to type your password each time you toggle.

To enable Powertop and deactivate/activate Turbo Boost:

pkexec powertop --auto-tune &&
pkexec sh -c ‘echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo’
&& notify-send “Mode Powertop activé”

pkexec sh -c ‘echo 0 > /sys/devices/system/cpu/intel_pstate/no_turbo’ && notify-send “Turbo Boost réactivé”

To choice powersave or performance governor:

echo performance | pkexec tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor && notify-send “Mode Performance activé”

echo powersave | pkexec tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor && notify-send “Mode Powersave activé”

It is sad that there is no active forum nor Reddit thread for Clear Linux, in order we can share our usages and tips about power usage : CL is very fast but it drain more power than Fedora, on the same laptop. I am pretty sure than some settings could be used for users like me who wants a bit more autonomy, but do not want to install tlp or so which reduce CL perf.

Thanks - cheers from France!

" there is no active forum " – in a message on the forum :wink:

we use powersave for laptops (or at least, it’s supposed to be that way, if it’s not the case on a specific laptop, that’s a bug we’d like to hear about)
