Make a little script, bind it to a hotkey. For me, I use Windows+S $ cat ~/bin/monitor-off.sh #!/bin/bash sleep .5 xset dpms force off Same little trick for when I lock the screen, (Settings -> Notifications -> Screen Saver -> Configure Events): cat ~/bin/LOCKSCREEN-ACTIONS.sh #!/bin/bash ## Anything that is "slow" should be run in the background otherwise lock/unlock is slowed down #Mute audio on screen lock, only if not already muted: ( if [[ "$(amixer get Master | awk '/Front Left:/ {print $NF}')" = "[on]" ]]; then amixer -q set Master mute touch "${HOME}/.audiomutedbylockscreen" fi ) & #Pause foobar2000 only if playing, and make a note. ( "${HOME}/bin/foobar2000-pauseonly.sh" && touch "${HOME}/.foopausedbylockscreen" ) & #Disable all mouses (to prevent movement waking monitor.) "${HOME}/bin/set-mice-status" disable #Force monitor to sleep. "${HOME}/bin/monitor-off.sh" And finally, I have the inverse of that, which is called on screen unlock, called automatically on screen unlock (Settings -> Notifications -> Screen Saver -> Configure Events): cat ~/bin/UNLOCKSCREEN-ACTIONS.sh #!/bin/bash #Unmute audio only if muted by lockscreen: ( if [ -f "${HOME}/.audiomutedbylockscreen" ]; then amixer -q set Master unmute rm -f "${HOME}/.audiomutedbylockscreen" fi ) & #Enable all mouses. "${HOME}/bin/set-mice-status" enable & #Unpause foobar2000 only if paused by lockscreen. Remove note. ( if [ -f "${HOME}/.foopausedbylockscreen" ]; then "${HOME}/bin/foobar2000-playonly.sh" rm -f "${HOME}/.foopausedbylockscreen" fi ) &
