Gnome /or/ KDE Plasma + NVIDIA not working as expected[SOLVED for now]

I have installed:

nvidia-dkms nvidia-utils nvidia-settings nvidia-prime opencl-nvidia switcheroo-control

and did:

sudo systemctl enable nvidia-persistenced switcheroo-control

I have also installed envycontrol because without it I was having some issues with older version of Minecraft(1.8.9), maybe it is adding some environment variables(I know I can add it manually) but still I would like to keep it installed because it allows me to switch to integrated CPU which can give me more 30-60 mins battery life when I am outdoors.

When I am on GDM neither gnome Wayland nor plasma Wayland shows up,
and when I login to Gnome(X11) from GDM everything works as intended and settings shows:

## Hardware Information:

and when I login Plasma(X11) from GDM everything works as intended but the info center shows(not showing NVIDIA Graphics):

Operating System: Arch Linux

But when I am on SDDM Wayland as well as X11 shows up,
and when I login to Gnome(Wayland) from SDDM everything works* as intended and settings shows:

- Kernel Version:                              Linux 6.7.8-zen1-1-zen

and when I login to Plasma(Wayland) from SDDM everything works* as intended but info center shows(not showing NVIDIA Graphics):

Note:

1. *Not everything works in Wayland with NVIDIA as Minecraft(1.8.9) crashes right after launching (this was happening in X11 also but installing envycontrol fixed the issue for X11).

2. I have systemd boot and adding nvidia_drm.modeset=1 to either kernel module parameter or kernel parameters doesn't do anything.

My Questions:

1. Is GUI option for switcheroo control not supposed to show in plasma just like it shows in gnome as "Launch using Discrete Graphics Card"? because it's quite bothersome to launch from CLI with prime-run or edit the .desktop.

2. Why plasma is not showing my GPU even though it is listed in LSPCI as 0000:01:00.0 3D controller?

3. Why GDM does not shows Wayland session? If it can then how?

4. Extra: Why pointer acceleration in plasma(X11) is slower than plasma(Wayland)? Changing the pointer acceleration in X11 from none to standard makes pointer faster in Wayland. (Not a big issue but it will better if i can solve it or at least know the reason)

THANKS TO EVERYONE WHO HELPS ME IN ADVANCE

1. Afaik not yet, but it's planned

2. A 3D controller means the card is generally speaking not attached to any display, so it won't be shown --or generally in  use -- if you're not using prime-run when starting applications you're expecting to give you GPU information, chances are the plasma info center just queries the currently actively rendering GPU, this is likely just cosmetic and ignorable.

3. because it's GDM, it expects you to do a specific configuration  before showing you a wayland session with a nvidia gpu present/or you telling it to ignore it's config rules: https://wiki.archlinux.org/title/GDM#Wa … DIA_driver

4. That should generally be possible in x11 as well. Will come down to how the plasma dialog configures the xf86-input-libinput X11 driver and how it configures libinput itself on wayland. You can potentially adjust that relevantly yourself on X11: https://wiki.archlinux.org/title/Libinput

I see. Thank you very much for answering my question.
Sorry to bother you again but do you have any idea for that "Minecraft(only older version) crash"?

Minecraft has a pseudo hard dependency on xorg-xrandr, is that installed? Maybe post terminal output from a minecraft attempt.

Yes the xorg-xrandr is indeed installed.

Maybe post terminal output from a minecraft attempt.

I am using GDLauncher and it throws not error while launching from terminal.

After a quick internet browsing the issue is something with older version of LWJGL(which was used in older version of Minecraft) not being compatible with NVIDIA drivers, so a workaround is to set "__GL_THREADED_OPTIMIZATIONS=0" as environment variable.

Is it okay? or do you suggest something else?

That's likely fine yeah. But don't set it globally, just set it for minecraft
