<!-- SC_OFF --><div class="md"><p>I followed this <a href="https://wiki.archlinux.org/title/PRIME#PCI-Express_Runtime_D3_(RTD3">guide</a>_Power_Management) to set up RTD3 on my laptop, added udev rules, added module parameters, enabled nvidia-persistenced service then reboot the computer but the output of <code>cat /proc/driver/nvidia/gpus/0000:01:00.0/power</code> said that RTD3 is not supported:</p> <pre><code>Runtime D3 status: Not Supported Video Memory: Active GPU Hardware Support: Video Memory Self Refresh: Supported Video Memory Off: Supported Power Limits: Default: N/A milliwatts GPU Boost: N/A milliwatts </code></pre> <p>I booted to Window and used Asus armoury crate to check and after a few seconds of inactivity the GPU tab will stop reading core/memory clock, voltage, etc, and <a href="https://imgur.com/a/Ou904KB">show</a> &quot;Power saving&quot;. And if I open a game (Apex legend) the GPU will turn on again and work normally. Which mean that RTD3 does work on my laptop and on Window only.
