Can't switch between gpu's after reboot.

I recently switched to ArchLinux as my primary os.
After first reboot optimus manager wasn't working but i was able to use prime-run to run programs on gpu.
In optimus manager's wiki it is saying not to use some display managers so i switched to gdm-prime and by the way I'm using Gnome as desktop manager.
It really annoyed me so i decided to remove nvidia drivers and reinstall them but after reinstallation I wasn't able to run X server.
After that, a friend of mine told me to downgrade my kernel to "5.10.5-arch1-1" so i switched my kernel from "5.10.6.arch1-1".
And after all it still is not working. Can you guys help me about that?

Here is some information about my system.
Output of "optimus-manager --switch nvidia"

If your login manager is GDM, make sure to follow those instructions:
https://github.com/Askannz/optimus-manager#important--gnome-and-gdm-users
If your display manager is neither GDM, SDDM nor LightDM, or if you don't use one, read the wiki:

I am kind of a new to GNU/Linux. Especially Arch. So if you need more information please let me know.

Re: Can't switch between gpu's after reboot.

For Optimus Manager to do anything together with prime-run you need to use the "hybrid" mode of optimus manager. Intel explicitly and intentionally disables the nvidia card for any use.

You don't even need Optimus Manager in the first place if you want to use prime-run.  FWIW there's no inherent incompatibility with the kernel and the current nvidia drivers there should be no issue in keeping it updated. In any case that doesn't appear to be the log file with the error Optimus manager complains about, can you double check you get the right one?

Your steam error shows that you at least also lack a few preconditions mentioned in https://wiki.archlinux.org/index.php/Steam#Installation

Switching to hybrid mode is not working too. And giving same error.

I checked "/var/log/optimus-manager/deamon/" and "/var/log/optimus-manager/switch/" both but no error logs.

It was working before prime-run got broken. I showed this as an example, neither any off the apps working with prime-run.
