This simple tutorial shows how to switch CPU power mode between ‘Performance’, ‘Balanced’, and ‘Power Saver’ using Linux command in Ubuntu 22.04, Ubuntu 23.10, and Ubuntu 24.04.<\/p>\n

GNOME has options in both ‘Settings’ and top-right system status menu to change CPU frequency by switching between ‘Performance’, ‘Balanced’, and ‘Power Saver’.<\/p>\n

It’s useful for saving battery life while being able to get better performance when gaming or doing heavy work.<\/p>\n

\"\"<\/a><\/p>\n

For users who want to bind the options to keyboard shortcuts, or make the function into script or even application, here’s the single command to switch the power mode.<\/p>\n

Single command to change Power Mode in Ubuntu<\/h3>\n

NOTE: This tutorial is only tested in Ubuntu (GNOME ONLY) with Intel CPU, though it should also work in Fedora workstation and Debian 12 with GNOME desktop.<\/p>\n

The power mode setting option is handled by the power-profiles-daemon<\/a>. It has a command line tool powerprofilesctl<\/code> to check current and switch power profile.<\/p>\n

To switch power mode to ‘power-saver’<\/b> for example, just press Ctrl+Alt+T<\/b> on keyboard to open terminal and run command:<\/p>\n

powerprofilesctl set power-saver<\/pre>\n
In command, replace power-saver<\/code> with balanced<\/code> or performance<\/code> as you want.<\/i><\/p>\n
After making change, verify by running command:<\/b><\/p>\n
powerprofilesctl<\/pre>\n
In the output, the one with an asterisk ‘*’ in the beginning is the power profile currently in use.<\/p>\n
\"\"<\/a><\/p>\n
For those who want to do the job through D-Bus interface<\/b>, run the single command below instead:<\/p>\n
gdbus call --system --dest net.hadess.PowerProfiles --object-path \/net\/hadess\/PowerProfiles --method org.freedesktop.DBus.Properties.Set 'net.hadess.PowerProfiles' 'ActiveProfile' \"<'power-saver'>\"<\/pre>\n
Also, change power-saver<\/code> in command with balanced<\/code> or performance<\/code> as need.<\/i><\/p>\n
\"\"<\/a><\/p>\n
View CPU Speed \/ frequency in Real Time<\/h3>\n
As mentioned, you can verify CPU power mode by simply running powerprofilesctl<\/code> command.<\/p>\n
For choice, you may also see CPU frequency (aka clock speed) in real-time by running command in terminal:<\/p>\n
watch -n 1 \"grep \\\"^[c]pu MHz\\\" \/proc\/cpuinfo\"<\/pre>\n
It will show you the speed for all CPU cores, and update every 1 second. As you want, you may replace number 1 in seconds (e.g., 2 for 2 s, or 0.5 for 500 ms).<\/p>\n
