NVIDIA Optimus and KDE

[sbob]

All;


I just installed Fedora 38 KDE spin on a laptop with an NVIDIA card.


Per the rpmfusion HOWTO NVIDIA page I have an optimus card since this 
command finds my card:

# lspci | grep -e 3D
0000:01:00.0 3Dcontroller: NVIDIA Corporation GA107M [GeForce RTX 3050 
Mobile] (rev a1)


The docs say that GDM/Gnome detects it automatically but I am running 
KDE, can someone point me to the right guide to use for KDE?  Do I just 
install akmod-nvidia ?


Thanks in advance

Yes, do classic akmod nvidia install. It is all good enough and for Optimus
you can see some commands for run as nvidia will work too

glxinfo | grep -E "OpenGL vendor|OpenGL renderer"
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: NVIDIA GeForce GTX 1050/PCIe/SSE2


I just check /usr/share/sddm/scripts/Xsetup and no need changes
anymore 

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto


in grub default (/etc/default/grub)  I added 

intel_iommu=igfx_off

and I also added 

export LIBVA_DRIVER_NAME=nvidia

yesterday I added to  /etc/sddm.conf

sorry is not /usr/share/sddm/scripts where we should looking for, is in
/etc/sddm/Xsetup and I still need add:  

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto


note, I disable intel graphic on boot with intel_iommu=igfx_off , this
ensure me, that I'm using NVIDIA Optimus.

If I don't do what is described before in sddm/Xsetup ,  sddm give me a
black screen .

Anyway sddm on boot have something wrong , I need run systemctl restart
sddm , to appears correctly . 


Best regards,
