PANEL POWER SAVINGS(9)

🌸 PANEL POWER SAVINGS 🌸

okay bestie, so this one lives in the Kernel API Manual and honestly it's a short little icon but it's important 💅

💖 the whole vibe

The display manager lets you set your desired panel power savings level — it's a number between 0-4, and 0 means off (so like, no savings, nap time over 🙈). You can set it, for example, like this:

# echo 3 > /sys/class/drm/card0-eDP-1/amdgpu/panel_power_savings

⚠️ okay listen — modifying this value can have implications on color accuracy, so tread carefully, fr fr. like, your colors might not be giving what they're supposed to give 😭
