From 9fe6d9e405d9b36ca47a8ad29a27e61df4cb9b5e Mon Sep 17 00:00:00 2001 From: Bernardo Magri Date: Sat, 6 Jun 2026 13:32:12 +0100 Subject: [PATCH] fix(walker): don't spawn a duplicate elephant alongside the service MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit nomarchy-launch-walker guarded its manual elephant start with `pgrep -x elephant`, which never matches the Home Manager service's actual process name `.elephant-wrapped` (Linux truncates comm to 15 chars). So every menu invocation spawned a second elephant that races elephant.service for the socket — a latent source of menus intermittently coming up empty. Gate on `systemctl --user is-active elephant.service` first, with a working `pgrep -f elephant-wrapped` fallback for non-service setups; do the same for walker.service. Verified in a headless system.build.vm: opening the theme menu now keeps the elephant process count at 1 (was 2) and the menu still renders.
