I have a laptop running Fedora 42 (Wayland) that has 2 graphics cards:
- Intel UHD Graphics @ 1.50 GHz [Integrated]
- NVIDIA GeForce RTX 4060 Max-Q / Mobile [Discrete]
I have installed a GNOME extensin called Freon that I use to monitor system average and Nvidia GPU temperature. Usually this indicator shows a temperature when GPU is used and N/A when not. Recently, I noticed that the GPU indicator started showing the 
sign, which appears when the extension cannot gather GPU information. Although the GPU seems to be unavailable for all applications. The issue is that I can’t identify which actions cause the error. It can just appear when I am just browsing the web (with only Zen Browser and Vesktop running) or after a gaming session.
What I tried:
The first thing that came to my mind was to reinstall the Nvidia drivers, maybe I just did a wrong installation in the past, or the update might have broken the previous settings.
I didn’t save the output, but it succeeded.
$ sudo dnf remove 'xorg-x11-drv-nvidia*' 'akmod-nvidia*' 'kmod-nvidia*' nvidia-settings nvidia-xconfig nvidia-modprobe nvidia-persistenced
$ sudo dnf autoremove
$ sudo rm -f /etc/X11/xorg.conf.d/nvidia.conf
$ sudo rm -f /etc/modprobe.d/nvidia.conf
$ sudo rm -f /etc/dracut.conf.d/nvidia.conf
$ sudo grubby --update-kernel=ALL --remove-args='rd.driver.blacklist=nouveau'
$ sudo grubby --update-kernel=ALL --remove-args='modprobe.blacklist=nouveau'
$ sudo grubby --update-kernel=ALL --remove-args='nvidia-drm.modeset=1'
$ sudo dracut --force
reboot
$ sudo dnf install kernel-devel kernel-headers gcc make dkms acpid libglvnd-glx libglvnd-opengl libglvnd-devel pkgconfig
$ sudo dnf install xorg-x11-drv-nvidia-libs.i686
$ sudo akmods --force
$ modinfo -F version nvidia
$ sudo dnf install nvidia-settings
$ sudo dnf install nvidia-vaapi-driver libva-utils vdpauinfo
$ sudo dnf install vulkan vulkan-tools
$ sudo grubby --update-kernel=ALL --args='rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1'
$ sudo mkdir -p /var/lib/dkms
$ sudo openssl req -new -x509 -newkey rsa:2048 -keyout /var/lib/dkms/mok.priv -outform DER -out /var/lib/dkms/mok.der -nodes -days 36500 -subj "/CN=DKMS module signing key"
$ sudo chmod 600 /var/lib/dkms/mok.priv
$ sudo mokutil --import /var/lib/dkms/mok.der
$ sudo tee /etc/dkms/framework.conf << EOF
sign_tool="/lib/modules/\$kernelver/build/scripts/sign-file"
mok_signing_key="/var/lib/dkms/mok.priv"
mok_certificate="/var/lib/dkms/mok.der"
EOF
reboot and enroll the key
sudo akmods --force --kernels $(uname -r)
After that, I thought the problem would go away, but it reappeared. I searched for a similar problem and found some tips that were supposed to help (but they didn’t). That time I saved the output:
eq@Lapwarmer:/$ sudo systemctl status nvidia-persistenced
[sudo] password for eq:
○ nvidia-persistenced.service - NVIDIA Persistence Daemon

eq@Lapwarmer:/$ sudo systemctl start nvidia-persistenced
eq@Lapwarmer:/$ nvidia-smi -q | grep -i persistence
Persistence Mode : Enabled
eq@Lapwarmer:/$
That didn’t solve it.
Then I thought, maybe the issue is with the suspension/hibernation of the system (once GPU errored right after I wake up the laptop), so I tried those:
$ sudo systemctl enable nvidia-suspend.service
$ sudo systemctl enable nvidia-hibernate.service
$ sudo systemctl enable nvidia-resume.service
$ sudo grubby --update-kernel=ALL --args='nvidia.NVreg_PreserveVideoMemoryAllocations=1'
That didn’t solve the issue either.
My guess
My guess is that it’s all related to system constantly switching between both GPUs and because of this dGPU for whatever reason got lost by the system.
Not sure, how frequent this issue is, would glad to get any help!
Some commands I can think of (currently the Nvidia GPU is ):
