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

Hi,

I think, if we follow the on-demand nvidia prime profile, we should access nvidia xorg modules over env variable like that and nor outputcalsss modulepath option.

one line,

ModulePath="/usr/lib/x86_64-linux-gnu/nvidia/xorg" __GL_SYNC_TO_VBLANK=0 vblank_mode=0 LIBGL_ALWAYS_INDIRECT=true mesa_glthread=false LIBGL_DRI2_DISABLE=true LIBGL_DRI3_DISABLE=true __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxgears

my 10-nvidia.conf

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"
EndSection

Section "OutputClass"
    Identifier "intel"
    MatchDriver "i915"
    Driver "modesetting"
    Option "PrimaryGPU" "Yes"    
EndSection

and my 11-nvidia-offload

Section "ServerLayout"
    Identifier "layout"
    Option         "Xinerama" "0"    
    Option "AllowNVIDIAGPUScreens"
EndSection

please look at my prints attached
