My Experience With XLibre on Intel + Nvidia Legacy 470 Hybrid Setup

[AmerXz]

I actually don't have much things to say

The experience is stable , and I'm using xlibre on arch with daily usage besides few things

First of all , I've needed to use Dlegacy_nvidia_padding=true meson option when compiling otherwise xlibre xserver would crash / freeze when doing "Prime render offload"

secondly , I was using @ONykyf 's Xlibre #658 Pull request and modify 10-nvidia.conf

in that config I change ModulePath to /usr/lib64/xorg/modules from the default value /usr/local/lib/nvidia/xorg

After switching from that Pull request to mainline (Without @ONykyf 's changes) nvidia would appear as modeseting instead of NVIDIA-G0 when using xrandr --listproviders (so instead of having one modesetting and the other to appear as NVIDIA-G0 , NVIDIA-G0 entry would appear as modesetting makes both "nvidia and intel' to appear as modesetting) Also nvidia-settings would not work

Anyway I solved these two issues by simply making links for the nvidia libraries with these commands

sudo ln -s /usr/lib64/xorg/modules/drivers/nvidia_drv.so /usr/local/lib/xorg/modules/xlibre-25/drivers/
sudo ln -s /usr/lib64/xorg/modules/extensions/libglxserver_nvidia.so.470.256.02 /usr/local/lib/xorg/modules/xlibre-25/extensions/
sudo ln -s /usr/lib64/xorg/modules/extensions/libglxserver_nvidia.so /usr/local/lib/xorg/modules/xlibre-25/extensions/

and these commands fixed xrandr --listproviders and nvidia-settings issues

I also did

sudo ln -s /etc/vulkan/icd.d/nvidia_icd.json /usr/share/vulkan/icd.d/

becuase some vulkan appilcations where complaining about not finding nvidia icd loader in /usr/share/vulkan/icd.d/ (I don't know if this vulkan issue was related to the first two but doing that command fixed it)

For more context : I'm using Arch but I didn't install the drivers from the aur
I installed the drivers from this github repo which had a script to install nvidia + new patches (I used the script from this repo instead of aur becuase the aur package was late to add newer arch kernel's patches and then I didn't bother to remove the drivers and install them from the aur)

As I said Xlibre on my setup is good right now and I'm using it in my daily usage (that even works in proton games) besides few quirks (which I already described)

I hope this info was useful , and thanks for the support

Thank you very much for your test and feedback! The information about what works, how, and under what circumstances is very valuable!
