Turn off ubuntu gnome screenlock

I don't know what Ubuntu 20.04 is doing but none of the UI settings work for shit in i3.

FINALLY found this, it gets it killed. To make it persistent, put this line in ~/.xsessionrc:

xset -dpms s off s noblank s 0 0 s noexpose

Other stuff that probably matches the UI and probably doesn't work:

gsettings set org.gnome.desktop.screensaver lock-enabled false
gsettings set org.gnome.desktop.screensaver idle-activation-enabled false
gsettings set org.gnome.desktop.session idle-delay 0
gsettings set org.gnome.settings-daemon.plugins.power idle-dim false

emacs ~/.xscreensaver
  timeout:	12:00:00    # the max timeout is 12 hours
crontab -e
  # So... I have .xscreensaver set to max delay (12 hours)
  # and I call this every ten hours to restart the idle timer.
