From 120ee3a0712594fb0c4fdf99c04f0e9d8874335d Mon Sep 17 00:00:00 2001 From: sommerfeld Date: Wed, 13 May 2026 13:43:33 +0100 Subject: fix(logind): ignore KEY_POWER short-press to stop Shokz dongle shutdowns MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Shokz OpenMeet dongle (3511:2EF2) emits KEY_POWER on USB enumeration and on headset power transitions, which logind handles with HandlePowerKey=poweroff and immediately shuts the host down. The previous attempt — an hwdb scancode remap of c0030 to reserved — sets the udev property correctly but the kernel does not honor EVIOCSKEYCODE for this device's HID consumer-page mapping (verified: KEY_POWER 116 still appears in the evdev keymap after udevadm trigger and libinput still reports it). Drop the hwdb file and the systemd-hwdb hooks from the etc deploy script. Replace with a logind drop-in that sets HandlePowerKey=ignore and HandlePowerKeyLongPress=poweroff. Single-tap power events from any source become no-ops; a 5s hold still shuts the machine down, so the real hardware-power-button safety net is preserved. Add a HUP to systemd-logind in the deploy script so the change takes effect without restarting the daemon. --- run_onchange_after_deploy-etc.sh.tmpl | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'run_onchange_after_deploy-etc.sh.tmpl') diff --git a/run_onchange_after_deploy-etc.sh.tmpl b/run_onchange_after_deploy-etc.sh.tmpl index adf00eb..d08f989 100755 --- a/run_onchange_after_deploy-etc.sh.tmpl +++ b/run_onchange_after_deploy-etc.sh.tmpl @@ -27,10 +27,9 @@ done # sudo-rs: /etc/pam.d/sudo-i is a symlink to /etc/pam.d/sudo sudo ln -sfT sudo /etc/pam.d/sudo-i -# Recompile the udev hardware database so any etc/udev/hwdb.d/*.hwdb files -# we just deployed take effect on next device event. -sudo systemd-hwdb update -sudo udevadm trigger --subsystem-match=input --action=change +# Reload systemd-logind so changes under /etc/systemd/logind.conf.d/ +# (e.g. HandlePowerKey overrides) take effect without dropping sessions. +sudo systemctl kill -s HUP systemd-logind # Make sudo-rs the system-wide sudo via /usr/local/bin precedence. # Targets may not exist yet on first bootstrap (sudo-rs is installed by -- cgit v1.3.1
