Xorg server not starting with nvidia-dkms on stock kernel [SOLVED]

Hello
I have installed the Liquorix kernel for gaming purposes.
As described in the arch wiki i then installed the nvidia-dkms package (https://wiki.archlinux.org/title/NVIDIA#Custom_kernel) and everything worked fine for a while, until i updated the lqx-kernel recently. (random freezing of programs like firefox)
I then reverted back to the stock linux kernel to see if the next update for the lqx-kernel fixes my issues (it does not), but had to find out the Xorg server will not start with nvidia-dkms on the stock kernel, so i installed the stock nvidia package again. Xorg starts fine.

However reading different forum post has lead me to believe that the stock linux kernel should work with nvidia-dkms as well so xorg should start (https://bbs.archlinux.org/viewtopic.php?id=179460). This post also mentions nvidia-hooks which i do not have installed because i dont plan to just throw stuff at a wall and see what sticks, after all i did not read anwyhere that i should install it when it comes to custom kernels or the stock one.

Reading the wiki page https://wiki.archlinux.org/title/NVIDIA#Custom_kernel about custom kernels tells me i need to make sure the following option is set as shown;

CONFIG_DRM_SIMPLEDRM=y

i thought the stock linux kernel may be missing this option which is why xorg starts on the lqx-kernel with nvidia-dkms but not on the stock kernel with nvidia-dkms. i tried to set this option by appending

nvidia-drm.modeset=1

to the grub.cfg like this

GRUB_CMD_LINE_LINUX_DEFAULT="loglevel=3 quiet nvidia-drm.modeset=1"

I still was not able to startx with the stock linux kernel and nvidia-dkms, but when i replaced nvidia-dkms with nvidia and started X, firefox also froze under stock nvidia and stock kernel so i deleted the line again.

At this point i am completely lost and dont know what i am missing, am i wrong that stock linux should work with dkms? Does anyone know what the issue could be? ideally i would like to use nvidia-dkms for both stock kernel and the lqx-kernel, installing different drivers every time i boot into one kernel or the other is just a workaround i found.

Thank you for your time

Did the module actually build when you installed it?

nvidia kernel module.

It's what dkms does.

See and this is why i am in the noob corner. i missed the headers for the stock linux kernel, but i had them for the lqx one, so it would build for the lqx-kernel, but obviously not for the stock one...

Thank you for pointing me in the right direction.
