How to set up laptop suspend in Regolith Desktop?

[zhandosweb]

Hello friends!

I have a newly installed Regolith Desktop under Ubuntu 25.10. Everything works properly except for laptop suspend.
At the end of the day yesterday, I left my laptop, and today when I tried to turn it back on, it wouldn't, because the battery was at 0%.

I'm using Ubuntu 25.10, and in a Gnome session, laptop suspend works as expected. Is Gnome power management not integrated with Regolith?

In the power settings tab, I have the following settings:

What is the correct way, recommended by Regolith, to set up laptop suspend? If you need additional info, please let me know.

Previously, using a custom Sway config, I used a simple setup like:

# sway idle
exec swayidle -w \
          timeout 180 'brightnessctl s 30%' resume 'brightnessctl s 70%' \
          timeout 600 'swaymsg "output * dpms off"; swaylock -f -c 000000' resume 'swaymsg "output * dpms on"' \
          timeout 1200 'systemctl suspend' before-sleep 'swaymsg "output * dpms on"'

Can I do something similar with Regolith? But under i3wm (x11) session, because I need I need to run specific Java/X11 apps which don't work properly under wayland.
