Worked on stabilizing multi-TTY input handling in the YaLTeR/niri repository, focusing on improving startup reliability for users switching between TTY sessions. Addressed a critical bug that caused input lock when the compositor was launched from an alternate TTY by implementing a session-active check at startup. This approach suspended libinput if the session was inactive, ensuring input devices were properly re-enumerated upon activation. The work required in-depth knowledge of Rust, system programming, and input handling, resulting in enhanced robustness for session management. The solution targeted a nuanced edge case, contributing to a smoother user experience during compositor startup and TTY transitions.
