GLX in nix-shell

README.md

How to solve Could not initialize GLX and similar errors?

Workaround (not recommended)

export QT_XCB_GL_INTEGRATION=none

This a workaround that works most of the times, but what about a proper solution?

NixGL (recommended)

Setup

nix-channel --add https://github.com/nix-community/nixGL/archive/main.tar.gz nixgl && nix-channel --update
nix-env -iA nixgl.auto.nixGLDefault

-- https://github.com/nix-community/nixGL?tab=readme-ov-file#nix-channel-recommended

On some NVIDIA systems, it is necessary to force the loading of NVIDIA libraries by adding this line to .bashrc or similar:

export __GLX_VENDOR_LIBRARY_NAME=nvidia

Run the app

Run you apps as usual:

nixGL nix-shell -p rstudio -p R --run rstudio

To avoid running each command using the nixGL wrapper, it is possible to set some environmental variables which will do the same (you might put them in your shellHook):

library_path="$LD_LIBRARY_PATH"
export $(env -i $(which nixGL) $(which printenv))
export LD_LIBRARY_PATH="$library_path:$LD_LIBRARY_PATH"

Thanks, this let me run anki-bin (where export QT_XCB_GL_INTEGRATION=none did not help), but installing nixGL took like half a gig :-/
