Black screen after display disconnection (wayland + nvidia)

Hi !

Here is what I believe is happening: When my screen is turned off for a long enough time, my display goes in stand by mode, and it can't recover an active screen afterward. In case the computer goes fully to sleep, this issue doesn't come up.

System:

• CPU: AMD Ryzen 9 7950X3D

• GPU rtx 4080 SUPER

• DE: Plasma 6 (wayland)

• DM: sdd (also tried ly)

• Bootloader: systemd-boot

• HDMI 2.1

What I have tried:

• sudo systemctl enable nvidia-suspend.service

• sudo systemctl enable nvidia-hibernate.service

• sudo systemctl enable nvidia-resume.service

• Creating

  /etc/modprobe.d/nvidia.conf

  with:

   options nvidia NVreg_PreserveVideoMemoryAllocations=1

• Adding

  nvidia_drm.modset=1

  to the boatloader

  /boot/loader/entries/*.conf

This allowed me to resume from sleep without problem, but the display shutdown issue still persist.

Could you upload your journal from before this error? You can use the following command:

sudo journalctl -b -1

Also nvidia parameters:

cat /proc/driver/nvidia/params

Nvidia, your parameters look good, but it seems like the journal is missing. You can try uploading the 0x0.st journal to its site.
