#Xscreensaver command code
#Xscreensaver command password

If the screen is locked, then the password dialog will pop up first, as usual. This means that if the screensaver is active (the screen is blanked), then this command will cause the screen to un-blank as if there had been keyboard or mouse activity.

This tells xscreensaver to pretend that there has just been user activity. (Because if you jiggle the mouse, xscreensaver will notice, and deactivate.) To be sure that you have time to take your hand off the mouse before the screensaver comes on.

It is useful to run this from a menu you may wish to run it as Tell xscreensaver to turn on immediately (that is, blank the screen, as if the user had been idle for long enough.) The screensaver will deactivate as soon as there is any user activity, as usual. Like the no-argument form of −demo, but brings up that program’s Preferences panel by default. (The first hack in the list is numbered 1, not 0.) When the −demo option is followed by an integer, it instructs the xscreensaver daemon to run that hack, and wait for the user to click the mouse before deactivating (i.e., mouse motion does not deactivate.) This is the mechanism by which xscreensaver−demo(1) communicates with the xscreensaver(1) daemon. This just launches the xscreensaver−demo(1) program, in which one can experiment with the various graphics hacks available, and edit parameters. Prints a brief summary of command-line options. Xscreensaver-command accepts the following command-line options: This program, xscreensaver-command, is a command-line-oriented tool the xscreensaver−demo(1). Xscreensaver(1) has a client-server model: the xscreensaver process is a daemon that runs in the background it is controlled by other foreground programs such as xscreensaver-command and xscreensaver−demo(1). The xscreensaver−command program controls a running xscreensaver process by sending it client-messages. Os.Xscreensaver-command - control a running xscreensaver process SYNOPSIS If GPIO.input(11): # Waits for motion signal from PIR on GPIO pin 11, then complete rest and exit

#Xscreensaver command code

For some reason i can't seem to paste the code without removing the formatting, but there's a tab on the line (if gpio.input 11.) and two tabs on each of the bottom three lines. The screensaver now successfully starts and stops upon the PIR receiving motion, however the script doesn't then loop, and i receive the same error as before. tup(pir_pin, GPIO.IN)The code successfully starts the screensaver, however, quickly stops it and returns the error. Os.system('xscreensaver-command -deactivate') #OS command for Xscreensaver program = Activate, turns on screensaver instantly If GPIO.input(11): # Waits for motion signal from PIR on GPIO pin 25, then com[plete rest and exit While True: # endless loop, waiting for nothing. Os.system('xscreensaver-command -activate') #OS command for Xscreensaver program = Activate, turns on screensaver instantly Print('less than 30 seconds to leave the sensor area.') Print('Motion Activated (PIR) Screen Saver') Pir_pin = 11 # Sensor pin 11 for data out of the PIR sensor Import RPi.GPIO as GPIO #read the GPIO pins Once the 30 minutes is up, the screensaver comes back on again. When a user swipes the PIR sensor, the screensaver is turned off for 30 minutes. My hope is that by default the screensaver (which is just a black screen) is on. As part of this i'm trying to incorporate a PIR sensor with a raspberry pi. I'm fairly new to programming, and am currently trying to build a 'magic mirror' for my partners 21st birthday present.
