You could probably watch dmesg and lock instantly. Probably along those lines:
while IFS= read -r line; do
if printf '%s\n' "$line" | grep [something here]; then
# lock screen
elif printf '%s\n' "$line" | grep [something else here]; then
# unlock screen
fi
done <<< "$(dmesg -w)"Or better yet, let udev trigger do the hard work of watching for you. Just add one line to /etc/udev/rules.d/99-my.rules file:
ACTION=="remove", ENV{ID_SERIAL}=="Pixel_3_0a7...", RUN+="/usr/bin/screensaver-lock-script"
udevadm monitor -upThanks! I wanted to force connecting the smartphone back on the user by making the check every couple of seconds and locking. For that reason event driven approach wasn't the best fit.
A few things: 1) your home directory (/home/qertoip/) is hardcoded in the .service file, 2) this assume you're using cinnamon-screensaver, for portability you should probably have a configuration var for "lock command" or similar, and 3) you should avoid the symlink setup for /usr/lib/systemd/system/, user .service and .timer files should be put in (or symlinked into) /etc/systemd/system (see man 5 systemd.unit).
