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. * */10 * * * /usr/bin/xscreensaver-command --deactivate >/dev/null
