Hi! After installing fedora 36 on default drivers it worked well. But Fedora didn’t identify my nvidia gpu thath’s why installed nvidia drivers according to instruction. Howto/NVIDIA - RPM Fusion. But after reboot system works slow. I tried to switch to xorg session, but it still the same.

Please post the output of inxi -Fzx ane lsmod | grep -iE 'nouveau|nvidia' so we can see if the drivers are loading and the actual GPU in use.

The nvidia drivers are definitely loaded and functioning.

Please try copying the nvidia.conf file in so X11 can use it then reboot and log in using xorg to see if that makes a difference.
sudo cp /usr/share/X11/xorg.conf.d/nvidia.conf /etc/X11/xorg.conf.d/

I already did it.

cat /etc/X11/xorg.conf.d/nvidia.conf 
#This file is provided by xorg-x11-drv-nvidia
#Do not edit

Section "OutputClass"
	Identifier "nvidia"
	MatchDriver "nvidia-drm"
	Driver "nvidia"
	Option "AllowEmptyInitialConfiguration"
	Option "SLI" "Auto"
	Option "BaseMosaic" "on"
	Option "PrimaryGPU" "yes"	
EndSection

Section "ServerLayout"
	Identifier "layout"
	Option "AllowNVIDIAGPUScreens"
EndSection

P.S - I followed this instruction

There is one thing I have that is different in that file.
I added the ‘Option “PrimaryGPU” “yes”’ to both the ServerLayout and the OutputClass sections.

I do not however have your nvidia/amd combo but instead have an intel/nvidia combo.

The nvidia GPU will only be seen as primary when xorg is used as the DM (logged in using xorg). It also can only use hardware acceleration when running under xorg.

If not using hardware acceleration the graphics slows down because of software rendering.
