Nvidia Blank screen after wake

Bazzite
1

Hi there

So after sleeping the monitor will fail to wake most times.
The system is still responsive as I can ssh into it and i can here sound when pressing keyboard or controller.

System specs:
󱋩  bazzite-deck-nvidia:stable 
󰣛  Bazzite 42 (FROM Fedora Kinoite)
  Linux 6.14.6-109.bazzite.fc42.x86_64
󰾰  B650I AX
󰻠  AMD Ryzen 5 7600X (12) @ 5.46 GHz
󰍛  NVIDIA GeForce RTX 4060 [Discrete]

What i have tried:
sudo rpm-ostree kargs --append=“amd_iommu=off”
sudo rpm-ostree initramfs --enable
sudo rpm-ostree kargs --append=‘nvidia.NVreg_PreserveVideoMemoryAllocations=1’ --append=‘nvidia_drm.modeset=1’
sudo reboot

If you’re on NVIDIA with KDE and a monitor won’t wake from sleep or freezes (especially when toggling Night Light), try setting its “Color Profile” to anything other than “None”

Any other suggestion?

I have the exact same motherboard, CPU and GPU. Had the same issue and it seems setting a color profile helped. The issue was two fold: The PC wakes from sleep instantly (which this fixed it using `ostree kargs`) and the monitor is blank after sleep which the color profile fixed.

Update: 15 days later and this does not work anymore, no idea why

Changing the color profile fixed it for me. But then it broke after 2 hours

I have the same issue with AMD CPU and NVIDIA GPU. Changing profile colours worked only if i don’t have plug in external monitor. With external monitor i have black screen after wake up

same issue here with aurora nvidia, you ll note that wake up from sleep works with fedora 42 and 43, kde distro, here s my relevant hardware:

CPU: AMD Ryzen 7 7840HS w/ Radeon 780M Graphics
Memory: 32041 MB
Graphics Card: NVIDIA GeForce RTX 4050 Laptop GPU/PCIe/SSE2

issue solve with:

sudo rpm-ostree kargs --append=mem_sleep_default=deep

It worki for me to. What does this do? Could it be applied to Bazzite?
