From 01df321e907b6c8568bb8622eb44a5c1486a0631 Mon Sep 17 00:00:00 2001 From: sommerfeld Date: Fri, 29 May 2026 11:18:13 +0100 Subject: feat(suspend): hold inhibit lock while any zellij session exists MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The SSH-shell inhibitor in dot_zprofile is bound to the lifetime of the login shell, so it disappears the moment the user detaches a zellij session and disconnects — defeating the whole point of using zellij for persistent remote work. Add a user-scope path+service+watcher trio that ties the inhibit lock to the existence of zellij sessions instead: - dot_local/bin/executable_zellij-inhibit-watcher Polls `zellij list-sessions --short` every 15s, exits when none remain. Override poll interval via $ZELLIJ_INHIBIT_POLL. - dot_config/systemd/user/zellij-inhibit-suspend.service Wraps the watcher in `systemd-inhibit --what=sleep:idle:handle-lid-switch --mode=block`. When the watcher exits, the service stops and the lock is released. - dot_config/systemd/user/zellij-inhibit-suspend.path Activates the service whenever $XDG_RUNTIME_DIR/zellij becomes non-empty (i.e. zellij creates its first session socket). Re-fires on every empty→non-empty transition. Enable via systemd-units/user.txt (the .path unit; the service is on-demand). The existing SSH-shell inhibitor is kept as a backstop for non-zellij remote sessions and is now documented as such. VM (nix/vm.nix) deliberately not updated: the Ubuntu remote-dev VM never suspends, so the inhibit machinery would be inert there. --- systemd-units/user.txt | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'systemd-units') diff --git a/systemd-units/user.txt b/systemd-units/user.txt index 009b2b3..77ba788 100644 --- a/systemd-units/user.txt +++ b/systemd-units/user.txt @@ -18,3 +18,9 @@ wob.service # --- mail (overridden via drop-ins in dot_config/systemd/user/) --- protonmail-bridge.service + +# --- suspend inhibitor: keep host awake while any zellij session exists --- +# Enable the .path unit; it activates the service on-demand when zellij's +# socket dir becomes non-empty.
