systemd xscreensaver lock and suspend on lid close

21 Jul 2014

i editted one file, /etc/systemd/logind.conf, by uncommenting the line under [Login]

HandleLidSwitch=suspend

then i created the file /etc/systemd/system/xscreensaver.service with the contents

[Unit]
Description=Lock X screen using xscreensaver
Before=sleep.target

[Service]
User=rbruns
Type=oneshot
Environment=DISPLAY=:0
ExecStart=/usr/bin/xscreensaver-command -lock

[Install]
WantedBy=sleep.target

then finally enabled it with

# systemctl enable xscreensaver

tada. lid closes and when i reopen, xscreensaver asks for my password.

as an extra, i added this rule to udev to sleep when the battery gets to 2% (or less) giving me time to run and plug in before it powers off.

inside /etc/udev/rules.d/99-lowbat.rules

# Suspend the system when battery level drops to 2% or lower
SUBSYSTEM=="power_supply", ATTR{status}=="Discharging", ATTR{capacity}=="2", RUN+="/usr/bin/systemctl suspend"
SUBSYSTEM=="power_supply", ATTR{status}=="Discharging", ATTR{capacity}=="1", RUN+="/usr/bin/systemctl suspend"
SUBSYSTEM=="power_supply", ATTR{status}=="Discharging", ATTR{capacity}=="0", RUN+="/usr/bin/systemctl suspend"

now done.
