If this is not what you want, change the logged-in user's GNOME settings (via gnome-control-center or the /org/gnome/settings-daemon/plugins/power dconf tree). While a user is logged in, their per-user settings take effect, unless systemd-logind is configured to forbid that. The default in GNOME is to suspend after 20 minutes, to comply with European and American energy-saving legislation. smcv
