HI,

On nvidia on-demand profile there's noneed,
/usr/share/doc/xserver-xorg-video-intel/xorg.conf file; e

you can mv to /usr/share/doc/xserver-xorg-video-intel/xorg.conf.old

I recommend only vulkan and opengl-over-VK from steam lib games
cross-platform (top 5 xD)
Lutris|Proton can load dxvk as we know ...

With this "mastigating" we could only setup,

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

Only one provider modesetting/intel
In this way we can load opengl games using opengl-over-VK layer or via
PRELOAD as described last thread and with nvidia related outputclass
exclusive. We need more tests

aTT,

LF
