Worked on the nix-community/home-manager repository to address a compatibility issue affecting Proton and Lutris integration on NixOS. Focused on NixOS configuration and package management, the developer resolved a bug where Proton packages were not properly detected by Lutris v0.5.20 and newer. By aligning Proton package linkage with the Wine directory, the fix ensured that Proton packages became visible and usable within Lutris, improving software compatibility for end users. The solution was implemented in Nix, with updates to project documentation and release notes to clarify the changes and provide validation steps, supporting future troubleshooting and ongoing maintainability.
