I am running Arch Linux with the i3 window manager. Today I switched from lightdm to xorg-xinit. I have read the available documentation, and configured things so that startx will start and run the X server, and i3wm runs fine after that. However, I have one very important problem that I cannot find an answer to.

I have a Nvidia GPU with proprietary drivers installed, and I have created a file named 10-nvidia-drm-outputclass.conf in the /usr/share/X11/xorg.conf.d/ directory. The contents of that conf file are as follows:


Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    Option "Coolbits" "28"
    ModulePath "/usr/lib/nvidia/xorg"
    ModulePath "/usr/lib/xorg/modules"
EndSection



An important line in that file is the Option "Coolbits" "28" line, as it allows me to set a custom fan speed for my GPU, which I need for these warmer months.


When I use startx that conf file is not being read, it seems. It is completely ignored, and I am unable to set a custom fan speed.

Is there a conf file for xinit that I can use, create, or configure that will access the 10-nvidia-drm-outputclass.conf file, so that the GPU will run cooler via a custom fan speed?

When using lightdm, it works like a charm. But as I say, xinit seems to not see/read/access that file.

Any help would be greatly appreciated!!
