Linux: Switch to performance mode when AC adapter is plugged in

There is no setting in GNOME to switch to performance mode when the AC adapter is plugged into the laptop.

A slight continuation of Linux: Razer Blade 15 2022 - QHD 240Hz - GeForce RTX 3060.

Configuration

List available profile modes

$ powerprofilesctl list
* performance:
    Driver:     intel_pstate
    Degraded:   no

  balanced:
    Driver:     intel_pstate

  power-saver:
    Driver:     intel_pstate

Create rules to set performance mode

As root run:

cat <<EOF > /etc/udev/rules.d/99-power-profile.rules

SUBSYSTEM=="power_supply",ENV{POWER_SUPPLY_ONLINE}=="0",RUN+="$(which powerprofilesctl) set power-saver"
SUBSYSTEM=="power_supply",ENV{POWER_SUPPLY_ONLINE}=="1",RUN+="$(which powerprofilesctl) set performance"
EOF

Test

1. Either reboot (sudo systemctl reboot) or sudo udevadm control --reload-rules && sudo udevadm trigger.
2. Plug in AC adapter and then run powerprofilesctl get.
3. Unplug AC adapter and then run powerprofilesctl get.

The values should change from performance to power-saver between steps 2 and 3.
