@tr1xem Hi. Can you check out my comment here https://github.com/NVIDIA/open-gpu-kernel-modules/issues/905#issuecomment-3196986429 and see if your issue is related to mine (GPU oscillates between d0 and d3cold)?

@tr1xem Hi. Can you check out my comment here #905 (comment) and see if your issue is related to mine (GPU oscillates between d0 and d3cold)?

it got fixed in 575

other than that tlp was issue because of it gpu cant sleep i removed tlp

Now gpu sleeps it just turns on for a bit while opening a xwayland app (hyprland mis config from myside as my pervious config is broken due to update) but yep above 575 everything works good for me

options nvidia NVreg_UsePageAttributeTable=1 \
    NVreg_InitializeSystemMemoryAllocations=0 \
    NVreg_DynamicPowerManagement=0x02 \
    NVreg_RegistryDwords=RMIntrLockingMode=1 \
    NVreg_EnableS0ixPowerManagement=1
    

my config

@imaGuru Unfortunately this solution didn't work for me. However, I found out that for my issue, the GPU can go in and out of d3cold when nvidia_drm.modeset=0 is true. Unfortunately, when modeset is set to 0 my external monitor doesn't work because the HDMI port is directly connected to the NVIDIA GPU.
