How to change laptop power management from powersave to performance
by gllisse from LinuxQuestions.org on (#6G7A0)
Hi,
I have a pcspecialist laptop with i7-1360P 32 Gb ram and 2Tb 990 pro nvm ssd and I have installed dual boot on this laptop, with Windows 11 pro and Ubuntu 22.04 LTS.
When I run passmark performance 11 test with ubuntu I get 13 000 score for CPU running it with Ubuntu where as I get 20800 running the same test with Windows 11.
The difference is so important that I guess the laptop performance is deliberately diminished by linux but don't know how to get the full performance of it.
In Settings menu, I have set Power mode to Performance, but if I type in a terminal cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor, I only get powersave as result.
I have tried to set /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor to performance but it doesn't work, sys/devices/system/cpu/cpu*/cpufreq/scaling_governor all stay equal to powersave
I've also tried slimbook software,and to modify /etc/default/grub without success ( adding
GRUB_CMDLINE_LINUX="cpufreq.default_governor=performance" , updating with update-grub and rebooting )
The passmark score stays the same between 13000 and 15000 and cmd :
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
still results only to powersave for each cpu core.
Any ideas ?
Thx a lot !
