I was trying out booting my pi4 into a chromium kiosk mode for a demo and ran the commands from the following post: Open chromium full screen on start up
@xset s off @xset -dpms @xset s noblank @chromium-browser --kiosk http://google.com/
Now when I went to that file again it seems to be empty and I'm not able to revert the change.
I tried looking for the reverse commands like
@xset s on @xset s blank
Here's the output of I got from the commands in the comments:
pi@raspberrypi:~ $ ls -l /home/pi/.config/lxsession/LXDE-pi/autostart -rw-r--r-- 1 root root 37 Jul 24 16:05 /home/pi/.config/lxsession/LXDE-pi/autostart pi@raspberrypi:~ $ cat /home/pi/.config/lxsession/LXDE-pi/autostart @xset s on @xset -dpms @xset s blank
