Set Optimus environment variables on Wayland

[es20490446e]

Since on Wayland most window managers and apps run on EGL, it is easy to support automatic Optimus switch on it for all games, by just having the file below.

/etc/profile.d/optimus.sh

#! /bin/bash

if [[ "${XDG_SESSION_TYPE}" == "wayland" ]]; then
	export __GLX_VENDOR_LIBRARY_NAME="nvidia"
fi

Hi @es20490446e,

This makes sense and feels like a clean, pragmatic approach 👍
On Wayland, relying on EGL already removes a lot of the legacy GLX complexity, so setting __GLX_VENDOR_LIBRARY_NAME=nvidia globally for Wayland sessions seems reasonable, especially for games.

One thing to consider is scoping: exporting this system-wide might affect non-game apps or hybrid setups unexpectedly. Maybe limiting it to a launcher script or documenting when this is safe vs risky would help adoption.

Overall though, this is a nice example of how Wayland simplifies Optimus handling compared to X11.

Thanks for your reply.

This isn't a question, but rather a suggestion for making the feature standard. Either by putting the code within this repository, or mentioning it in the documentation.

The proposed solution has been the default on Optimus Manager for a while, and nobody mentioned that they were experiencing issues with it.
