Yeah, I just went through this process myself on steam deck and the fact it can't access opengl or vulkan natively makes anything that isn't terminal based a massive pain in the ass.

There is nixgl which you can wrap around any executable to make it work and it's got support in home-manager (https://nix-community.github.io/home-manager/options.xhtml#o...) but it's a huge annoyance having to wrap `config.lib.nixGL.wrap <package>` around everything you want to install.
