humble.rviz2 not working, Unable to create glx visual

Do I need to install nixgl? qt5.base can't be installed manually

There seems to be at least two problems:

1. If you use non-NixOS Linux distro, you should use nixGL or something similar. This is the command that I use. It works on Wayland desktops:

   QT_QPA_PLATFORM=xcb nix run --impure github:guibou/nixGL -- rviz2

2. Your flake uses two different versions of nixpkgs. One version is a dependency of nix-ros-overlay, the second is your nixpkgs input. The best is, in most cases, to use the same version as nix-ros-overlay, i.e., instead of pkgs = nixpkgs.legacyPackages.${system}; use pkgs = rospkgs.inputs.nixpkgs.legacyPackages.${system};

Thanks for your reply!

I fixed 2 and tried nixGL, but

$ QT_XCB_GL_INTEGRATION=none nix run --impure --override-input nixpkgs nixpkgs/nixos-unstable github:guibou/nixGL -- rviz2

This might be related to Nvidia driver https://github.com/NixOS/nixpkgs/issues/85866#issuecomment-1003618138

I have the same error if I don't have QT_QPA_PLATFORM=xcb in my environment. Try adding it as in my example above.

[etherswangel]

I've exported QT_QPA_PLATFORM=xcb actually, glxinfo also fails so it's probably not about QT or ros-overlay.

$ nix run --impure --override-input nixpkgs nixpkgs/nixos-unstable github:guibou/nixGL -- gl

In this case I'd need more information to help. What's your Linux distribution, which GPU (and drivers) do you have and which desktop environment do you use? Also, does accelerated graphics (e.g. glxgears) work in the underlaying distro?

[etherswangel]

1. Void Linux
2. AMD Radeon Vega Mobile Series (Ryzen 5900hx) and Nvidia GeForce RTX 3070 Mobile / Max-Q (Driver Version: 535.98)
3. i3wm
4. works fine

Thank you very much for your help. Should I raise an issue on guibou/nixGL instead of this?
